    Integrated Equipment Ratings

  • 5Introduction

    Low voltage distribution systems require the generalneed of continuity of supplyand safety to personnel andequipment. The reliable andsafe distribution of electricalpower is dependent upon theuse of protective devices formaking and breaking circuits,detecting the presence of faultcurrents, and for isolating afaulty circuit with least disturbance to the system. In addition, the assemblieswhich house and provide interconnection points for protective devices play animportant role in this reliabilityand safety perspective. All these matters must be considered when designing,developing, operating andmaintaining a modern electrical power system.

    Electrical standards of Canadaand the USA provide two different methods of applyingassemblies such as panelboards, switchboards,etc. into an electrical system:

    Fully RatedThe short circuit protectivedevices at all levels have a rating that matches or exceeds the system available fault level.

    Series Rated or IntegratedEquipment Rating (IER)The electrical standards permit the use of downstream equipment(such as moulded case circuit breaker panelboards)with protective devices having lower interruptingratings than the availablesystem fault level whenprotected by an upstreamfully rated device. This "series" application ofupstream and downstreamdevice must comply withCSA/UL standards whichrequire that any installationsupplied in this fashionmakes use of deviceswhich have been tested as a series combination.

    Description

    The upstream protectivedevice may be either a moulded case circuit breakeror a fuse (Class R, J, T or L). In the event of a major faultboth upstream and downstream devices willopen. The let-through currentis limited by the simultaneousopening of both devices to avalue which can be safelycleared. The upstream devicethus protects the lower-rateddownstream device. The resultant series ratingwhen applied to a productassembly is known as anIntegrated Equipment Rating.

    Circuit Breakers

    A downstream circuit breakertested in combination with an upstream circuit breakermay be assigned a series connected rating. These circuitbreakers can utilize either thermal-magnetic trip units or electronic trip units and can be 80% or 100% rated. When, the downstream circuit breaker is tested in a piece ofdistribution equipment, suchas a panelboard, the net resultis that the panelboard willhave an Integrated EquipmentRating. Design of the equipment and selection ofbreakers is based on short circuit interruption tests specified and witnessed byCSA/UL. Because the devicesand the equipment are testedas a system, the manufacturercan provide and warrant thisIntergrated Equipment Rating.

    Fuses

    Don't apply fuses using theup-over-down method. Thisgraphical/empirical method ofsizing an upstream current limiting fuse to protect downstream moulded case circuit breakers has been recommended by some fusemanufacturers. This selectionprocess is no longer permissible as the electricalstandards will now recognizeonly tested combinations.Moreover the Up-Over-Downmethod could lead to erroneous and unsafe conclusions because it treatsthe circuit breaker as a devicewith only a static interruptingcapacity characteristic. In fact, the circuit breaker hasa number of dynamic characteristics at play duringfault interruption ... one of themost dominant being thespeed of contact opening.These dynamic characteristicsvary greatly between circuitbreaker designs.

    For proper application of current limiting fuses, alwaysrefer to recommendations by the manufacturer of the circuit breaker and its assembly, which are based on actual test data.

    Circuit Protection andContinuity

    In applying IntegratedEquipment Ratings, the designengineer should understandthat this technique does notjeopardize circuit protectionand continuity when comparedto fully rated equipment performance.

    Integrated Equipment Ratingsgenerally apply to the 600Ampere and lower feederlevel. At the feeder level (i.e. upstream breaker), thedevice is fully rated. The userlevel device (i.e. downstreambreaker) is a standard interrupting capacity device.Whether the downstreambreaker is fully rated (see figure 1) or IER rated (see figure 2), co-ordinationand selectivity remain thesame. In BOTH Fully Ratedand Integrated EquipmentRating systems, a down-stream fault current higherthan the instantaneous tripsetting of the upstream breaker may result in both circuit breakers tripping. Thissituation is usually acceptablewhen one considers that thevast majority of faults are overloads or limited arcingfaults where time-currentselectivity still applies. Circuitcontinuity for IntegratedEquipment Rating systems isthe same as for fully rated systems when applied at 600Amperes and below.

  • 8CSA/UL Standards

    Moulded case circuit breakersare designed and tested toCSA Spec. C22.2 #5.1 and/orU/L #489. Both these standards include the testrequirements for verifying aseries combination rating. The short circuit tests are performed with the upstreamdevice and the downstreamcircuit breaker mounted in thesmallest enclosure in whicheach is to be used. Two shortcircuit shots are required; onewhere the fault is applied withboth devices closed, the otherby closing the downstreambreaker on the fault. After theshort circuit shots, the downstream device must passa calibration check carryingtwice rated current and adielectric withstand test.

    An intermediate interruptingtest may be required by thetesting agency if it is deemednecessary to verify the downstream breaker over theentire range of fault current.

    The short circuit test must be repeated if a manufacturerrequires a series rating withthe downstream circuit breaker mounted in a panelboard.

    The series requirements whichare now included in C22.2 #5.1are in the CSA CanadianElectrical Code Part I, Rule 14-014, "Series RatedCombinations".

    Fault Calculations/Protectionof Downstream Devices and Equipment

    When applying IntegratedEquipment Ratings it is onlynecessary to evaluate theavailable fault current level (in symmetrical kA) at the lineterminals of the main orupstream device. This is sufficient because:

    The upstream/main device(circuit breaker or fuse) isfully rated for the availablefault level.

    The upstream device anddownstream assembly havea test-proven IntegratedEquipment Rating to meetor exceed the available faultlevel.

    The let-through current and energy below the downstream breaker is at or below the level of let-through for the downstream device at itsrated fault capacity. In thismanner downstream cablesand loads are protected as normal.

    Selection

    To develop a series connectedprotective system, it is suggested that the designengineer, after completing preliminary steps:

    Define available fault currentat the line terminals of theupstream breaker.

    Select an upstream breakerwith an interrupting ratingequal to or greater than theavailable fault current.

    Verify the IntegratedEquipment Ratings of theselected equipment byreferring to the tables in thisbrochure. Tables show themaximum main or upstreamfuse or breaker frameampere rating. The IER combination applies fromthe minimum to the maximum fuse or breaker frame rating.

    Confirm, during commissioning, that the correct breakers have beeninstalled by checking thenameplates appearing onthe equipment.

    Motor Loads

    In most applications, panelboards feed non-motor or low inductance loads, andtherefore, there is no requirement to consider motorcontribution when selectingseries combinations using theIER charts. However, if thedownstream panelboard feedsmotors through its branch circuit breakers then due consideration should be givento the motor fault contribution.

    CEC Part 1, Appendix B, Noteson rules; 14-014 states that"Where motors are connectedin the system between theseries connected devices, anysignificant motor contributionto the fault current should beconsidered. It is generallyagreed that the contribution ofasynchronous motors to theshort circuit current may beneglected if the sum of therated currents on motors connected directly to the pointbetween-the series connecteddevices is 1% or less of theinterrupting rating of the downstream circuit breaker.(See IEC Publication 60781)."

    For those situations where the total motor load is abovethis level, fully rated circuit breakers should be considered.

  • 9Panelboard Marking

    Downstream panelboards containing branch circuit breakers which are beingapplied on the basis of a seriesrating must be clearly markedto indicate the following: (Figure #3)

    Short circuit rating Upstream breaker type Branch breaker type

    Apply and replace breakersprudently since the interruptingcapability of an IntegratedEquipment Rating panelboardis based on specific upstreamand downstream devices asmarked on the panelboardlabel. It is absolutely essentialthat any additional or replacement breakers be ofthe same type and rating asindicated on the label.

    Other Applications of SeriesRatings (IER)

    Series ratings can also beapplied under the following:

    Any fully rated breaker canbe applied upstream, downstream or in the middleof any of the series ratingsstated in tables.

    Any series rating stated in the tables may have additional series ratedbranch breakers of the exact same type further downstream in that rating.

    Combining series ratings areallowed under certain conditions. Main and branchratings may be combined if:

    Breakers A, B, and C are inseries respectively frommain to branch. Breakers Aand B series rate togetherBreakers A and C series rateat the same fault level (orhigher). Then it is allowableto use A, B and C togetherat the A-B series rating.

    It is improper to combineseries ratings under the following condition:

    Breakers A, B, and C are inseries respectively frommain to branch. Breakers Aand B series rate together.Breakers B and C series rateat the Breaker B interruptingrating leve1. It is not allowable to use A, B and Ctogether at the A-B seriesrating. However combiningmultiple overcurrent devicesas in this example, can beaccomplished if all devicesin the series combinationhave been tested together.

    Summary

    The utilization of this technique will result in a number of benefits withoutsacrificing either safety or reliability:

    Reduction of Panelboard initial cost and size, sincedownstream breakers arerated only for the prospective short circuitfault current at their point of application.

    Requirement of fault calculations for downstreamproduct selection is eliminated.

    Downstream circuit breakers are readily available, volume producedand standard interruptingtype.

    Application and WorkedExample

    Figure 3 shows a typicalschematic that demonstratesthe use of IntegratedEquipment Ratings. The mainService Switchboard includes a 1600 amp incoming mouldedcase circuit breaker whichfeeds a power panelboard in a distribution section of theboard. It is assumed that thefault current of 40 kA is available at the power panelboard bus since the main 1600 amp circuit breaker provides little or no current limitation. The diagram also indicates thata 400 amp branch breaker inthe distribution section feeds adownstream Lighting andDistribution Panel.

    Using the IER Charts

    The selection of this downstream lighting and distribution panelboard usingIntegrated Equipment Ratingsis achieved as follows:

    Step 1 Look at the given information. (Figure 4)

    System Operating Voltage:600Y/347V

    Fault Level Available: 40kA Upstream Breaker Amps:400A

    Downstream Breakers Amps: 2 and 3 pole 15-150A, 1 pole 15-30A

    Step 2 Determine the type of panelboard.

    System operating voltage is600Y/347. There are twotypes of panelboards thatoperate at this voltage:Pow-R-Line 2a and 3a. Since some branches aregreater than 100A, the Pow-R-Line 3a must be used.

    Step 3 Select and use the IER chartcorresponding to the panelboard chosen. (Figure 5)

    First, go to the left most column and select the Voltage Level- for this example: 600Y /347V (A).

    Next, select the Fault Levelassociated with that voltage from the Fault Level Availablecolumn. Use the next highestvalue if the exact level is notshown - for example: 40kA - go to 42kA (B).

    Now, select the Main or Upstream Breaker Type Amperage. Proceed horizontally to the columnwith the required ampere rating of upstream device -400A (C).

    Finally, proceed verticallydown from this amperage (C), and horizontally across from the fault level (B).Where these intersect, (D),read the required upstreamdevice, - KDC. Note: If no main or upstreambreaker or fuse is shown,then go to a higher fault levelthat shows a device protecting the particular branch breakers. If one is notshown, then a good combination does not exist.

    The upstream device selectedis a KDC3400 breaker withstandard rated FDB 14kAbranch breaker.

    That's INTEGRATED EQUIPMENT RATINGS!
