John,

Where do I start?

TR receptacles, AFCI, Poor wording in the NEC. For example, "As soon as possible", "On or near", "And similar areas".

I get this question all the time.
How come you can use #2 AL to feed a whole house at 100amp, but you have to fuse it at 90 amp if it is a feeder.

Sump pumps on GFI's?

The copper bus bar is not UL listed for AL but the gen panel says that all connections are listed for CU/AL?

These are some of the questions I get all day long from different contractors.
