Bpbbo, If you hare some elcheapo HF volt ohm meters laying around already, won't they suffice for the testing?

The no contact tester will tell him immediately which wire is the hot wire. Using an el cheapo VM he will have to test each wire pair to determine which wire is hot. Just faster and easier. And safer since it is no contact and he can't shock himself. But, to answer your question, yes the el cheapo VM will give him that information, if he knows how to use it.
