I am wiring a home theater and the equipment will be installed in the basement on a rack. The specs call for two 20 amp isolated ground receptacles. The basement is not finished and the rack will be in front of the receptacles. I am not sure if these are required to be gfi protected under the exceptions to 210.8 A (5). I don't think so but I'd like other opinions. Thanks Scott

I would think both exception No. 1 and No. 2 would apply.

210.8 Ground-Fault Circuit-Interrupter Protection for Personnel.

(A) Dwelling Units.

(5) Unfinished basements

Exception No. 1: Receptacles that are not readily accessible.

Exception No. 2: A single receptacle or a duplex receptacle for two appliances located within dedicated space for each appliance that, in normal use, is not easily moved from one place to another and that is cord-and-plug connected in accordance with 400.7(A)(6), (A)(7), or (A)(8)

Isolated ground, isolated from what in a typical residence?

If you run it in NM from a main panel it will be isolated, as long as you don't mount the box to a water pipe.

But if the customer thinks it is better what can you do.
