Within the RCS switchboard the branch and feeder devices are individually mounted. Because of this method of mounting, access to outgoing cable terminations must be from the rear of the switchboard. Bus bar extensions from the feeder devices are run back to the rear of the unit for easy access. The front and rear of all sections align, designed for mounting away from the wall. RCS switchboards will accommodate systems up to 6000 amperes, 600 volts maximum in any three-phase three-wire or three-phase four-wire configuration. The main bus can be specified for 600 to 6000 ampere rating. Main devices and bus ties are available up to 5000 amperes, branch devices up to 2000 amperes. The RCS switchboard can be of indoor or outdoor NEMA 3R construction.
