78Appendix A: Breaker Control Bus (BCB) installationPRC-E Series Instruction Manual MN014003EN August 2015 www.eaton.comAppendix A: Breaker Control Bus (BCB)installationThe BCB is designed to fit easily into the Eaton PRL1a andPRL2a panelboard models. The standard 1a/2a applicationcan be converted to a PRCEP panelboard by installingone or two BCB modules. A factory-produced PRCEPpanelboard should contain one or two pre-installed BCBmodules. A factory-installed SLAN cable will be includedto connected right and left BCBs. If this was not a factory-ordered option, it will be necessary to install the BCB intothe Pow-R-Line 1a/2a panelboard containing BABRSP orGHQRD circuit breakers. BCB kits were developed for theseretrofit applications. Pre-made BCB-to-BCB SLAN cables canbe selected from the table below.Description Catalog NumberController-to-BCB / 42-circuit panelboard PRCSLAN42Controller-to-BCB / 30-circuit panelboard PRCSLAN30Controller-to-BCB / 18-circuit panelboard PRCSLAN18Controller-to-BCB / 42-circuit w/right-side BCB only PRCSLAN42RController-to-BCB / 30-circuit w/right-side BCB only PRCSLAN30RController-to-BCB / 18-circuit w/right-side BCB only PRCSLAN18RBCB-to-BCB / 42-circuit panelboard PRCSLAN42BBCB-to-BCB / 30-circuit panelboard PRCSLAN30BBCB-to-BCB / 18-circuit panelboard PRCSLAN18BBCB retrofit kitsBCB retrofit kits include a BCB, mounting screws, andconnector covers. The BCB unit is interchangeable betweenthe left side and right side of the panelboard, therefore theretrofit kit is configured to cover one side of a 42-, 30-, or18-circuit panelboard. The BCB kits available are in 21-, 15-,and 9-circuit configurations. An example of use, a 30-circuitpanelboard with controllable circuit breakers on both sideswould require two 15-circuit retrofit kits.Figure 27 15-Circuit Breaker BCB Retrofit Kitm WARNINGDISCONNECT THE MAIN POWER FROM THE PANELBOARD. THEFOLLOWING PROCEDURES REQUIRE REMOVAL OF PROTECTIVECOVERS AND SHIELDS RESULTING IN POSSIBLE EXPOSURE TODANGEROUS AND/OR DEADLY VOLTAGES!Figure 28 BCB OrientationThe BCB is designed to fit either side of a Pow-R-Line 1aor 2a panelboard. The PRC-E Series Web browser interface,color LCD touch screen, or optional Lighting OptimizationSoftware (LOS) is used to configure the BCB for properassociation with circuits in the panelboard. Refer to the“LCD Programming” and Web page programming sectionsof this documentation for assistance with configuring andorienting the BCB.Step 1 Remove the trim piece.Different designs and options have different trim pieces.It is beyond the scope of this document to describe eachpossibility. Please refer to the Instruction Leaflet providedwith the panelboard.Step 2 Remove the deadfront cover.Remove the four screws holding the perforated frame to thepanelboard chassis. Figure 29 shows a typical detail of thetop-left screw to be removed. There should be an identicalscrew at, or near, each corner of the deadfront cover.Description Catalog NumberBreaker control bus (BCB)—21 circuits—retrofit kit PRC1000BCB-21RBreaker control bus (BCB)—15 circuits—retrofit kit PRC1000BCB-15RBreaker control bus (BCB)—9 circuits—retrofit kit PRC1000BCB-9R
