Flexibility for Multiple Applications

Spectra Bolt-On Power Panel:• Circuit Breakers attached through bolted copper connections• TVSS Unit• Main Lugs• Metering Modules

Spectra Plug-In Power Panel:• Circuit Breaker Modules• Fusible Switch Modules• Intermix of Circuit Breaker and Fusible Switch Modules• TVSS Unit• PCU Modules• Main Lug Modules• Metering Modules

Each interior is fully rated; therefore large amperage devices can be installed at either the top or bottom of the interior. The vertical design of the bus maximizes convective heat transfer. The bus bar insulator system provides short-circuit protection, 600-volt spacing (without having to add baffles). There is no need for any additional insulation.

GE Tranquell TVSS (Transient Voltage Surge Suppressor)provides outstanding protection from internally and externallygenerated transients.

Spectra Bolt-On Power PanelThe Spectra Bolt-On Power Panel provides economical solu-tions for your application needs. The design features mainlugs or main and branch circuit breakers bolted to the busbars. The factory-installed main lugs are bolted directly to thebus bars; circuit breakers are bolted with mounting straps.The Spectra Bolt-On power panelboard is rated for 100,000AIC. Fusible switches are not available in the bolt-on design.

Main lug assembly

Aluminum mechanical lugs are standard, copper and compression lugs are optional. The lugs are rated from 250to 1200 amps, and offer front accessible set screws.

Circuit breaker assembly

Circuit breakers are bolted to the bus bars with coppermounting straps utilizing anti-turn clips that simplify align-ment when field-installing breakers. The mounting straps aresized according to the breaker frame, not the trip amperage,and are rated for 100,000 AIC.

Enclosure DepthAll circuit breaker panel enclosures are 11.5" deep. Whendoor over devices is required, a 14.25" deep box is providedfor the 27", 31", and 40" wide enclosures and a 16.25" deepfor the 36" and 44" wide enclosures.

Enclosure Locks

Available door locks include an optional Corbin lock (far left), standard GE lock, optional T-handle and optional Yale lock.

Neutral and Equipment GroundingAssembliesNeutral bar assemblies are available in ratings from 250 ampsto 1200 amps. These neutrals have provisions for bonding andgrounding when required. The number of circuits has beenpre-engineered, depending on the amp rating. They can bemounted in either corner of the enclosure in the same endwhere the main device is installed. Each neutral is fully rated.

Equipment ground assembly

Isolated ground assembly

Isolated ground kit when required is field installed on either side

Power panel neutralsMechanical lugs are copper/aluminum as standard.Compression and oversized lugs are optional. Equipment-grounding modules are available either as bonded or isolated(refer to the National Electrical Code Article 250-74, Exception4). In special applications where non-linear loads are a concern,a 200% rated neutral can be installed.

Series-Connected RatingsUL permits assigning a short circuit rating to a combination ofmolded case circuit breakers or fuses and molded case circuitbreakers connected in series that is higher than the lowestrated protective device of the combination. This is defined asseries connected ratings. The combination rating cannotexceed the rating of the protective device furthest upstream,although it will exceed the rating of the downstream protector.

The upstream protector can be a molded case breaker orfuse. Device combinations are not limited to those in the sameequipment. They can be in different equipments such as aswitchboard feeder or a panelboard main versus panelboard

branches. Any distance between devices in different equip-ment is permitted. Total fault current magnitude must flowthrough both protectors. Thus, fault current contributionfrom motors, as well as power source fault current, mustflow through upstream and downstream protectors.

It appears NEMA’s position will allow motor full load currentsnot exceeding 1% of the downstream device interrupting ratingto be ignored.

Molded case circuit breakers may be applied as fully rated orseries rated. In a fully rated system, the short circuit ratingsof all protective devices are equal to, or exceed, the availableshort circuit current. If mounted in equipment, the bus shortcircuit withstand rating and equipment short circuit ratingmust equal or exceed the available short circuit current.

In a series connected system, the short circuit rating of theupstream protector is fully rated but the downstream protectoris not fully rated.

Selectivity between overcurrent devices is always desirablebut, in some cases, it difficult to achieve without over-sizingdevices or using Low Voltage Power Circuit Breakers inswitchgear. However, the National Electrical Code requirescomplete selectivity in some types of circuits. As of the 2008NEC, these include Elevator Control Circuits (article 620.62),Emergency Systems (Article 700.27), Legally RequiredStandby Systems (Article 701.18) and Critical OperationsPower Systems (Article 708.54).

Complete selectivity is usually interpreted as meaning selec-tivity for ground faults and all magnitude of phase faults upto maximum theoretical bolted fault current level. Somejurisdictions enforce the pertinent articles of the code only asfar as short time and long time selectivity, usually using the0.1-second rule. Other jurisdictions enforce the requirementfor complete selectivity. It is advisable that the localJurisdiction Having Authority (JHA) be consulted to understandthe interpretation of the pertinent code articles for the application being considered.

Full selectivity may be achieved in various ways. Traditionally, itis achieved by ensuring that the instantaneous characteristicof circuit breakers in series does not overlap up to availablefault current at the load side device. However, it is now possible to achieve instantaneous selectivity of molded casecircuit breakers even when their instantaneous time curvesoverlap. The selectivity available varies significantly by circuitbreaker model and size. To see available selectivity with GEcircuit breakers, please use GE publication DET-537. Beforeselecting circuit breakers for a panel or switchboard in circuitsor applications that may be regulated by the aforementionedcode articles, it is advisable that the interpretation enforcedby the local JHA be understood and that circuit breakerselection be undertaken with a full understanding on how toachieve the selectivity required.

Refer to GE publication DET-008A (in the latest edition) for complete series rating listings.

Interrupting RatingsPanelboards have integrated short-circuit ratings. Whenfully rated, the rating is that of the lowest-rated device in thepanelboard. When series-connected rated, the rating is thatof the main and branch-tested/UL Listed combination.

Short-Circuit Ratings - Fusible Switch UnitsThe short-circuit or interrupting rating of the fusible switch isthe lower of the fuse or the switch rating. Spectra Seriesswitches have a 200,000 amp short-circuit rating.

Note: Only panelboards containing all UL Listed devices canbe UL labeled.

In addition to meeting or exceeding all applicable standardsshown above, Spectra Series Power Panels meet GE’s morestringent internal requirements, offering a greater margin ofperformance and protection.

The following classifications and limitations of panelboardshave been established by the Underwriters’ Laboratoriesand the National Electrical Code.

Note: An overcurrent protective device is a circuit breaker pole or single fuse.

Lighting Panelboards as per NEC 2005• More than 10 percent of panelboard circuits are rated 30amps or less, for which neutral connections are provided.

• Maximum 42 overcurrent protective devices per panel(including subfeeds but not main overcurrent protectivedevices). If more than 42 are required, two or more separatepanelboards must be used. Example: A two-pole device isconsidered as two overcurrent devices.

• When two or more separate panelboards are used, subfeedlugs or thru-feed lugs (of same capacity as incoming mains)must be included in all sections except the last one. Cablesor bus bars for interconnection are not included.

Power (or Distribution) Panelboards as per NEC 2005There is no limitation as to the number and rating of branchcircuits, except as determined by available enclosures.

Note: NEC 2008 no longer distinguishes lighting and appliance panelboards from distribution panelboards.

Service Entrance Equipment• Must be located near the point of entrance of building supply conductors.

• Lighting and appliance panels must have one, but notmore than two, main disconnections with a current ratingequal to or less than panelboard rating.

• Power panelboards may have up to six operating handlesto entirely disconnect panelboard from the source.

• Main disconnect must include ground fault protection if itprovides more than 150 volts to ground, and a maximumcurrent rating of 1,000 amps or more.

• Must include connector for bonding and grounding neutralconductor.

• A service entrance-type UL label must be factory-installedand will be provided on the equipment (when specified).

Service Conditions Equipment is rated for operation underthe following usual service conditions, unless limited by thedevices contained in the equipment. Unusual service conditions should be referred to the factory. These includedrequirements such as seismic, corrosive or explosive atmospheres, vibration, shock and unusual operating duties,and temperature.

Altitudes Equipment is rated for use up to a certain altitude.Above these altitude values, which vary dependent on thetype of equipment being considered, the continuous currentand voltage rating may require modification to account forincreased temperature and lower dielectric strength.Standard ratings may be applied up to the following altitudes:

Spectra Series® Power PanelboardsApplication Data

For derating correction factors to be applied when the alti-tude exceeds the above, refer to the equipment applicationbulletins or factory.

Ambient Temperature Equipment is rated for use in a givenambient, and if exceeded, the continuous current ratingrequires derating. Rating correction is required if applied inan ambient exceeding the following:

Table 27. Ambient Derating

For derating correction factors to be applied when the ambi-ent exceeds the above, refer to the equipment applicationbulletins or factory.

Current. The continuous current carried by a protectivedevice should not exceed 80% of the device rating unlessthe equipment or assembly, including the protective device,is listed for continuous operation at 100% of its rating. Acontinuous load current is one that continues for threehours or more. A noncontinuous load current may be 100%of the device rating.

Low-voltage fusible switches are standard-rated 80% excepthigh pressure contact and bolted pressure switches, whichare 100% rated. Molded case circuit breakers equipped withthermal magnetic trips are standard-rated (80%). Whenequipped with electronic trips, they can be standard (80%)or 100% rated.

When mounted in equipment, MCCB and fusible switches ingroup-mounted configuration are all standard (80%) rated. Inindividual mounted configuration, MCCB with electronic tripcan be standard (80%) or 100% rated. Insulated case circuitbreakers are standard (80%) or 100% rated. Low-voltagepower circuit breakers, type AKR, medium-voltage fuses, andmedium-voltage breaker PowerVac are all 100% rated. Low-voltage protective devices are fast operating and their short-circuit rating is based on the maximum current during thefirst half cycle of fault current flow. The total fault current atinitiation of fault consists of two components: the ac and dccomponents. The ac component is defined as the symmetricalrms current, and ac plus dc, the asymmetrical rms current.The magnitude and rate of decay of the dc component is afunction of the reactance to the resistance (X/R) ratio. Low-voltage protective devices are rated on the basis of

symmetrical rms amps, but tested at known X/R ratios toassure capability of interrupting the total fault currentasymmetrical fault. The X/R ratios at which they are testedare as follows:

Table 28

Thus, the low-voltage protective device interrupting ratingsymmetrical rms must be equal to, or greater than, the circuitsymmetrical rms fault current and test X/R equal to, orgreater than, circuit X/R at point of application. If the circuitasymmetrical current should be greater than the protectivedevice will withstand, then the protective devices interruptingrating must be derated. Derating factors are identified in theapplicable application bulletins and standards.

Medium-and high-voltage fuses are rated in terms of sym-metrical current, but can withstand the total asymmetricalcurrent provided the X/R ratio does not exceed 15. If the circuitwhere applied exceeds an X/R of 15, then it is necessary toderate the symmetrical current rating in accordance withthe applicable standard. Proper application of medium- andhigh-voltage breakers requires that the circuit-short-circuitduties during the first cycle (momentary), and at contactparting time (interrupting), be compared with the circuitbreaker’s short-circuit capability to close and latch duringthe first cycle, and to interrupt at some time later. Refer toGET 3550 to determine methods of calculating short-circuitcurrents for proper application.

TerminologyAmbient Temperature is the temperature of the surroundingmedium that comes in contact with a fuse or breaker.

Ampacity is the amount of current a fuse will carry continuouslywithout deterioration, or a circuit breaker without tripping andwithout exceeding temperature rise limits specified for a particularfuse or circuit breaker by NEC requirements and UL standards.

Amp Setting, Adjustable varies the continuous current-carryingability of a breaker through a predetermined range.

Arcing Fault is a high-impedance connection, such as an arcthrough air or across insulation, between two conductors.

Arcing Time, in a fuse, is the amount of time that elapsesbetween the melting of the current-responsive element, suchas a link, to the final circuit interruption. Arcing time isdependent upon such factors as circuit voltage and impedance.

Available Short-Circuit Current is the maximum rms (root-mean-square) symmetrical current at a given point in a power system.

Branch Circuit is the circuit conductor between the finalovercurrent device protection and the outlets or point of use.

Bus Bar is a solid aluminum or copper alloy bar that carriescurrent to the branch or feeder devices in a power panelboardor switchboard. There is a least one bus bar for each phase ofthe incoming electrical service.

Compression Lug, also called a crimp lug, is a lug that iscrimped to hold cable.

Continuous Load is when the maximum current is expectedto continue for three hours or more. (NEC Article 100)

Current Density is the amount of current traveling through amember (cable, bus bar, etc.). It is a cross-section measurementof the member in amps per square inch.

Current Sensors monitor and measure line-to-load andreturn line-to-line current. An imbalance causes a relay tosignal the breaker to trip at a preset time and current level ifground fault function is present.

Dead Front construction is where energized parts are notexposed to a person on the operating side of the equipment.

Electrical Service or System is the conductors and equipmentwhich delivers energy from the electrical supply system to thewiring system of the premises served. The service or systemconsists of the number of phases, number of wires, voltages

and amps. Type of service determines the number of poles onthe main device, the numbers of poles valid for feeder orbranch devices, and the minimum voltages for 1-, 2-, or 3-pole breakers and fusible switches.

Enclosure is a constructed case to protect personnel againstcontact with the enclosed equipment and to protect theenclosed equipment against environmental conditions.

Filler Mounts on side of fusible switch module, circuit breakermodule, or between side trims to cover the front of the enclosure.The fillers plus trim comprise the enclosure front around theinstalled devices.

Frame Size is a specific size of breaker with a specific rangeof amp ratings. For example, an F-frame breaker is availablein ratings of 70 amps to 225 amps in a 225 amp frame.

Front is the part of the panelboard that protects the interiorof the panelboard from environmental elements and preventsaccidental contact with the panel’s interior live conductors.

Fuseholder or Fuse Block is an assembly of fuse clips andinsulation for mounting and connecting a fuse into the circuit.

Fusible Switch is a device that can switch off current flowand to which a fuse(s) is added to protect conductors.

I2t is the measure of heat energy developed within a circuit, inwhich I2 stands for effective let-through current squared, andt is time in seconds.

Interior The side rails, bus bars and insulation system thatmounts in the enclosure. It is energized through the main device(lugs, fusible switch or circuit breaker) and in turn energizes theinstalled circuit protective devices (fusible switch or circuit breaker).

Interrupting Rating is the highest rms-rated current a fuseor breaker is intended to interrupt under specified conditions.

Jaw Metal parts that grip the interior bus bar and conductelectricity to the module bus bars. The jaws are spring-reinforced to provide a highly reliable electrical connection.

Line refers to the incoming (live) side of equipment or device.

Load is the outgoing (switched) side of equipment or device.

Lug is a device to terminate cables.

Magnetic Trip is synonymous with instantaneous trip anddescribes a tripping acting with no intentional time delay.Current exceeding the magnetic trip level will actuate thetrip mechanism and open the breaker contacts immediately.

Main Device is a fusible switch or circuit breaker that can isolate the panelboard from incoming power.

Main Lug is the connecting means between the incomingservice cable and the bus bar.

Mechanical Lug is a terminal with one or more wire bindingscrews that are tightened to hold the conductor or cable.

Overcurrent is any current in excess of the rated current ofequipment or the ampacity of a conductor that can resultfrom an overload, a short circuit or a ground fault.

Pole The number of output terminals on a fusible switch orbreaker that must be insulated and separated from each other.

Power Panelboard is any panelboard that is not a lighting orappliance panelboard as specified by UL and NEC and is notlimited as to the number and rating of branch circuits, exceptfor available spacing and physical size. The dead-front panel-board is accessible from the front only.

Quick-make, Quick-break The action of a mechanism wherethe speed of the contacts in opening and closing a breakeror fusible switch is not controlled by the operator.

Rejection Fuse and Clip is a combination of Class R fuses and clips that will not accept fuses with a lower short-circuitrating. This type of fuse and clip has a mechanism thatrejects standard NEMA Class H fuses.

Rotor Mechanism in fusible switch unit that mechanicallyensures all switch blades open/close simultaneously.

Selective Tripping is the application of circuit breakers orfuses in series, so that, of the breakers or fuses carrying faultcurrent, only the one nearest the fault opens and isolatesthe faulted circuit from the system.

Series-Connected Rated Panel means the UL Listed short-circuit rating of the panel is equal to the IC rating of themain protective device when properly applied with itsbranch circuit protective devices.

Service Disconnect is a device or group of devices that dis-connects all ungrounded conductors.

Service Entrance Equipment, such as power panelboard,consists of a fusible switch or breaker located near the pointof entrance of supply conductors to a building and serves asthe main control and disconnect of electrical power. Serviceentrance equipment must include a connector for bondingand grounding the neutral conductor at the entrance point ofthe supply conductors and bear a UL service entrance label.

Shunt Trip opens a fusible switch breaker by remote control.

Single-Branch A mounting module that is sized to acceptone fusible switch unit or circuit breaker. A single-branchfusible switch module may have one fusible switch unit factory-installed on one side, and the other side specifiedempty (blank) to facilitate installing future expansion kits.

Thermal Trip protects against sustained overloads. Abimetallic element reacts time-wise in inverse proportion tothe current. If a circuit is overloaded, heat from excessivecurrent flow causes the bimetal to bend, actuating the tripmechanism to open the breaker.

Time Delay is a term used by NEMA, ANSI and UL to denote aminimum opening time of 10 seconds on an overload currentfive times the amp rating of a circuit breaker or Class H, K, Jand R fuses. Time delay is useful to let through momentarycurrent inrushes, such as in motor startups, without inter-rupting the circuit.

Trim The four pieces of painted steel (top, bottom and eachside) that cover the front of the enclosure. The trim plusfillers comprise the enclosure front.

Trip Function is that portion of the breaker that senses faultconditions, controls the associated logic functions and initiatesand powers the breaker trip device.

Trip Mechanisms are independent of manual control handles.The breaker will trip when a fault occurs, even if the handleis held in the “ON” position.

Undervoltage release instantaneously trips the breaker whenvoltage (control or line) drops to 30%-70% of nominal rating.

Voltage is electrical pressure that moves electrons througha conductor and is measured in volts.

Voltage Rating is the rms alternating current voltage atwhich a fuse or circuit breaker is designed to operate.

X Value is a vertical measurement of the usable mountingspace on a panelboard for a fusible switch or breaker. X isequal to 1 3/8 inches (1.375”). Height of the interior is thesum of the horizontally mounted, panel-mounted components.

Section 7 STEPS TO BE TAKEN BEFORE ENERGIZING

7.1 ACCESSIBLE ELECTRICAL CONNECTIONS

Tighten all accessible electrical connections to the manufacturer's torque specifications. If such information is not provided with the equipment, consult the manufacturer. 7.2 BLOCKS AND PACKING MATERIALS

Make certain that all blocks and packing materials used for shipment have been removed from all component devices and the panelboard. 7.3 SWITCHES, CIRCUIT BREAKERS, AND OTHER OPERATING MECHANISMS

Manually exercise all switches, circuit breakers, and other operating mechanisms to make certain they operate freely. Check the integrity of all electrical and mechanical interlocks and padlocking mechanisms. For key interlocked systems, assure that only the required number of keys are accessible to the operator. 7.4 SHORT CIRCUITS AND GROUND FAULTS

To make sure that the system is free from short circuits and ground faults, conduct an insulation resistance test phase to ground and phase to phase with the switches or circuit breakers in both the open and closed positions. If the resistance reads less than 1 megohm while testing with the branch circuit devices in the open position, the system may be unsafe and should be investigated. If after investigation and possible correction, low readings are still observed, the manufacturer should be contacted. Some electronic equipment (metering, TVSS, etc.) may be damaged by this testing. Refer to the manufacturers equipment markings for guidelines. 7.5 GROUND FAULT PROTECTION SYSTEM

Test the ground fault protection system (if furnished) in accordance with the manufacturer's instructions. See Section 230.95 of the National Electrical Code and NEMA Standards Publication PB 2.2, Application Guide for Ground Fault Protective Devices for Equipment.

7.6 ADJUSTABLE TIME CURRENT TRIP DEVICE SETTINGS

Set any adjustable time current trip device settings to the proper values. NOTE—Experience has indicated that damage from overcurrent can be reduced if the devices used for overload and short-circuit protection are set to operate instantaneously (that is, without intentional time delay) at 115 percent of the highest value of phase current which is likely to occur as the result of any anticipated motor starting or welding currents. 7.7 GROUNDING CONNECTIONS

Check to determine that all grounding connections are properly made. If the panelboard is used as service equipment, make certain that the neutral, if present, is properly bonded to the cabinet.


PB 1.1-2007 Page 14

7.8 FOREIGN MATERIAL

Remove all foreign material from the panelboard and cabinet before installing the cabinet front. Make certain that all deadfront shields are properly aligned and tightened. Install the cabinet front in accordance with Section 8.

Section 9 ENERGIZING EQUIPMENT

WARNING—HAZARDOUS VOLTAGES IN ELECTRICAL EQUIPMENT CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ENERGIZING A PANELBOARD FOR THE FIRST TIME AFTER INITIAL INSTALLATION OR MAINTENANCE IS POTENTIALLY DANGEROUS. 9.1 QUALIFIED PERSONNEL

Only qualified personnel should energize equipment for the first time. If short circuit conditions caused by damage or poor installation practices have not been detected in the procedures specified in Section 7, serious personal injury and damage can occur when the power is turned on. 9.2 LOAD ON THE PANELBOARD

There should be no load on the panelboard when it is energized. Turn off all of the downstream loads. 9.3 ENERGIZED IN SEQUENCE

The equipment should be energized in sequence by starting at the source end of the system and working towards the load end. In other words, energize the main devices, then the feeder devices, and then the branch-circuit devices. Turn the devices on with a firm positive motion. 9.4 LOADS SUCH AS LIGHTING CIRCUITS, CONTACTORS, HEATERS, AND MOTORS

After all main, feeder, and branch circuit devices have been closed, loads such as lighting circuits, contactors, heaters, and motors may be turned on.


PB 1.1-2007 Page 17

Section 10 MAINTENANCE

10.1 MAINTENANCE PROGRAM

A maintenance program for panelboards should be conducted on a regularly scheduled basis in accordance with the following: 10.2 PANELBOARD WHICH HAS BEEN CARRYING ITS REGULAR LOAD FOR AT LEAST 3

HOURS

A panelboard which has been carrying its regular load for at least 3 hours just prior to inspection should be field tested by feeling the deadfront surfaces of circuit breakers, switches, interior trims, doors, and enclosure sides with the palm of the hand. If the temperature of these surfaces does not permit you to maintain contact for at least 3 seconds, this may be an indication of trouble and investigation is necessary. Thermographic (infrared) scanning has become a useful method of investigating thermal performance. WARNING—HAZARDOUS VOLTAGES IN ELECTRICAL EQUIPMENT CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. UNLESS OTHERWISE SPECIFIED, INSPECTION AND MAINTENANCE SHOULD ONLY BE PERFORMED ON PANELBOARDS TO WHICH POWER HAS BEEN TURNED OFF, DISCONNECTED AND ELECTRICALLY ISOLATED SO THAT NO ACCIDENTAL CONTACT CAN BE MADE WITH ENERGIZED PARTS. FOLLOW ALL MANUFACTURER’S WARNINGS AND INSTRUCTIONS. Safety related work practices, as described in NFPA 70E, should be followed at all times. CAUTION—Hydrocarbon spray propellants and hydrocarbon based sprays or compounds will cause degradation of certain plastics. Contact the panelboard manufacturer before using these products to clean, dry, or lubricate panelboard components during installation or maintenance.

10.3 INSPECT PANELBOARD ONCE EACH YEAR

Inspect the panelboard once each year or after any severe short circuit. 10.4 ACCUMULATION OF DUST AND DIRT

If there is an accumulation of dust and dirt, clean out the panelboard by using a brush, vacuum cleaner, or clean lint-free rags. Avoid blowing dust into circuit breakers or other components. Do not use a blower or compressed air. 10.4.1 Visible Electrical Joints and Terminals

Carefully inspect all visible electrical joints and terminals in the bus and wiring system. 10.4.2 Conductors and Connections

Visually check all conductors and connections to be certain that they are clean and secure. Loose and/or contaminated connections increase electrical resistance which can cause overheating. Such overheating is indicated by discoloration or flaking of insulation and/or metal parts. Pitting or melting of connecting surfaces is a sign of arcing due to a loose or otherwise poor connection. Parts which show evidence of overheating or looseness should be cleaned and re-torqued or replaced if damaged. Tighten bolts and nuts at bus joints to manufacturer’s torque specifications.


PB 1.1-2007 Page 18

CAUTION—Do not remove plating from aluminum parts in joints or terminations. Damage to plating can result in overheating. Replace damaged aluminum parts. 10.4.3 Fuse Clip Contact Pressure and Contact Means
