My original post was edited. My frustration is the fact that there is very little training material specific to the ICC E2 exam, Unlike the B2, P2., and M2.
As a Building Inspector all I need is an approved set of prints. If it matches the prints I sign the card. I am not a plan checker or Electrical Engineer. I do not need to know theory or how to do calculations. I have passed every ICC exam the first time , (residential and commercial), with the exception of the commercial electrical. And yes I know NEC is under NFPA.
I don't care how a watch is built. I just want to know what time it is.
