Our guys are completing a job that another contractor started. It is a 1200A/600V service. we ran conduit from anew transformer pad to an existing electrical shack that was fed from a Generator. The shack has a 1200A unfused disconnect feeding a splitter that feeds 2 600A fused disconnects. Everything up to and including splitter is good for 1200A. Metering is transformer mounted. Do we need to swap out the 1200A unfused disconnect for a fused one? I say yes, inspector says maybe so far. He's going to get back to us.
This service is for a "permanent" construction camp. It has been running on Generators for a year and we are doing the permanent hookup. The reason the disconnect was non fused was because the Gen has a main breaker so the original contractor thought they'd save a few bucks. Inspector Says disconnect must be fused as the consumer service starts at the meter(transformer). I would have included a picture but don't appear to have the mental faculties for that. (PS digging in frozen ground does suck....but hydrovac trucks make it easier.. although messier).
