Help guys,
I'm bidding a project which requires us to pull a 100 amps off an existing sub-panel(square D) rated at 225 amps.Thats not the problem, the problem is that the 225 amp panel is set over an existing panel used as a "pull box" with a 6"x8" cutout in the back of can for branch circuits(can't see upper conduits) and a 10"x8" bottom cutout for the feed conductors and branch circuits to come out of and land on breakers.This is a school so I have to fight the AHJ put this violates the UL Im sure.Any other NEC violations would be great.
 
Re: Panel boards

I`ll jump in the WATER ;) Some panel boards come without a bottom but are meant to be set on a concrete bench and the conduit enters the panel board in this manner.Ul listed for this.
In this case from the description you gave this was a violation in the first place.Not UL listed ,unused openings.No code referrence required common sensce takes over.Why not use a new J box that doesn`t encroach the panel clearance`s and drill holes to match what is there.Ul listed to be drilled,code compliant and IMHO a better job.Hope you bid it with this in mind or you have to eat the additional cost ;)
