    That is not entirely a true statement. While Hendrix cable is technically "covered" and not "insulated", it is available up to 46 kV. And, in general, it will prevent shocks and arcs when hit with incidental object contact. In fact, I have great pictures of a piece of Hendrix cable laying on a grounded metal "C" bracket for years with no arcing. After about 6 calls, the PoCo finally lifted it back up onto the chili bowl and tied it back in place.

    Absolutely! Otherwise, YOU become the employer and have to cover anything their policy doesn't. AND, it proves that they have liability insurance to begin with.
