this is a new dentists office with a 50ft long wall of salt water aquariums in front of all the chairs, with 125v and 250v pumps, transformers, etc for about 100amps of "plug in" equipment.... and no electrical installations by us, just supply the outlets.
there are cords hanging over the tanks tied up with tie wraps and screw in hooks, and 250v twist lock outlets just above some tanks below the fish tanks. i cant believe they dont have to have gfci protection, but i dont know how to tell them it is required because its not a bathroom, kitchen, rooftop, or pool/tub. any ideas? 250.114 is the only NEC reference i could find but that doesnt say gfci's are needed. tanks
