B3 Bypass breakers back feed the current without connection to the load center bus bar. Current passes through an internal bus bar back to the service line. B3 Bypass breakers are UL classified and are designed and tested to be both mechanically and electrically compatible with load centers from most service panels. Construction incorporates 2 duplex breakers assembled together to provide various combinations of 2-pole and single pole devices in a 2-inch package.
