After a cursory glance around the Engineering forum, it looks like the only "Codelike" categories deal with IEEE standards.
I've got to agree with Sparky. Maintenance Electricians should do just that...maintain. Even if allowed to pull permits, they usually don't, because management doesn't want any type of inspector in their plant.
I go into plants on a regular basis to fix goof-ups caused by the "in house" people. I've found disconnects wired backwards (change a fuse in that baby!), "permanently/temporary" installations of 100 amps 480..sans conduit, with the machine operator stepping on the wire now and then.
The list goes on and on.
