NOTE: 1. Accommodates one to eight UPMs. Four UPM system shown.
NOTE: 2. A bypass neutral feeder must be installed when the output neutral is used. If no bypass neutral is installed, the output neutral is to be bonded to the chassis in the SSBM through the minimum size copper conductor listed in Table H. In either case, fully rated neutral conductors are to be run from the output of each UPM to the neutral bus bar inside the SSBM.
