I certainly understand that the customer wants to have high-quality components in his electrical system, and in particular wants to avoid the cheapo "contractor specials" often found is residential work. But I don't see the sense in automatically disqualifying something because it's used in residential work. For example, THHN wire is used in residential work in some cases; are you going to not use THHN wire because of that?
It seems to me that he is looking for a particular quality level. Is there perhaps a better way of specifying that that he will be happy with?
