I have a job coming up in the next few weeks and I could really use some advice on what needs to be done up to code.
What I have is a separate building being fed from a multi-family dwelling. Two ungrounded conductors, and one grounded conductor (no ground), feeding a butcher block type business. The service to the building is under a 70 amp, 2-pole federal breaker at the main panel and #4 cu is being used.
At the point of attachment, the conductors are fed into a 1 - 1/4" RMC and LB'ed from there into the building. The panel is NOT at the nearest point of entrance and is at least 50' from the entrance point.
The work I'll be doing is re-attaching those service conductors to a new piece of RMC because the conductors are now secured by a vent stack. I know, lol, now I've seen it all.
My question is, since I'll be doing work to the service entrance, will I need to install a disconnect switch at the nearest point of entry inside the building? I've read the Code requirements in article 250.32 for the grounding update that I'll need to do. I just need to know if I NEED a new disconnect inside the building.
