I'm installing a 240V single phase service, feeding a 240x480 step up trans. The trans. feeds a phase converter 3 feet away. The calculated load on the trans. primary is low enough to easily meet NEC, 450.3B for primary protection only.
But with 240.21.c, I'm not sure, is over current before the phase converter required? The trans secondary will be 3 wire.
Thanks for your help.
