Having just adopted 2 code cycles there's a lot of stuff to absorb, and easily forgotten as well. Are the TR receps required everywhere? We are trimming a reptile enclosure in a residential back yard tomorrow, it has a work station with receps and some receps for heaters and fridge (for the reptile food). We are of course GFCI protecting everything but I am unclear on the TR requirements. This is basically a 10 x 20 shed built on a slab with a sub panel and insulated walls covered with siding on both sides. The reptiles (Iguanas) are going to be in cages with doggie doors to the outside, and as far as I know they won't be trying to stick things into the receps.
