It is measure of how much counter emf is generated in a circuit. ________
In order to wire a post light, a homeowner purchased some single-conductor cable that was marked as suitable for direct burial in the ground. A separate equipment grounding conductor to the post light was not carried. Instead, the bottom of the metal post, buried 2 ft (0.6 m) into the ground, was used as a ground for the post light. The inspector “red tagged” (turned down) the installation. Who is right—the homeowner or the electrical inspector?
Explain.
