Master66,

As John said, when I do my final res. inspection, I check about80-90% of the receptacles in the house to make sure of proper polarity. You look for either a light or switched on recp. in all rooms. I check ALL GFCI's, Not every light has to be there. ( i.e. sconce lights or fancy chandilers on back order.) as long as there is a temp. light. Check for HVAC in attic (with lights and recpt.) Check the service for proper markings, HVAC outside for correct OC protection. As for a good reference guide check out Joe Tedesco's "BASIC CHECK LIST FOR BUILDING ELECTRICAL INSPECTORS." It is a very good book. I was also making out a list of the top ten violations for roughs and finals.
