I have 200A to the house panel, and a double-pole 100A breaker in the house that feeds (through the proper-sized wire) a sub-panel in the shop.
Question: If I ever wanted to use the whole 100A in the shop (like say for a Sync 250 ) without having any lights on or any other loads, could I put a 100A double-pole breaker into the shop sub-panel, along with the proper-sized wire downstream to feed that circuit (AWG 4 I think) and be OK with the NEC?
Thanks in advance for any info.
