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.
An electrician is installing switches and receptacles in a house where the wall and ceiling coverings are installed. She knows that one end of a two-wire Type NM cable is in Box A but does not know whether the other end is in Box B or Box C. Using the procedure for using a continuity tester outlined at the end of Chapter 4 in the textbook as a guide, explain how she could use the continuity tester to determine which box contains the other end of the cable
For residential wiring, not less than one 15-ampere lighting branch circuit should be provided for every ____________ ft2 of floor area. If 20-ampere lighting branch circuits are used, provide one 20-ampere lighting branch circuit for every ____________ ft2 of floor area
