fuse and overload
fuse and overload
(OP)
sorry if this is posted, I'm sure it probly is, but didn't find anything...
I've inherited a bunch of drawings of which part are motor control cktry...typical input power-motor contactor-overload however, they all have fuses on all 3 phase wires before the contactor/overload. I knwo NEC says each phase wire must be fused, but is that in addition to the overload? Why?
