I am planning to install a buck and boost transformer to buck 277 to 240 to operate two motors one @ 15 Amps and other @ 24 Amps single phase.
The NEC 99 does not state anything about the secondary protection do i need a load center/subpanel on the secondary side of the transformer to protect the two loads?
The NEC 99 450-4 does not say anything about that except not put a OCPD in series with the shunt winding.

Edward


Thanks
