Chapter 3, Problem 37R
In the past, it was common practice to connect the lighting and receptacle(s) in a bathroom to the same circuit. Because of overloads caused by high-wattage grooming appliances, the Code now requires that these receptacle(s) be supplied by a separate 20-ampere branch circuit. Where in the Code is this requirement found? NEC __________

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

Assume you are an electrical apprentice. The electrical foreman on the job tells youto connect some equipment grounding conductors to the ground bus that runs alongthe front bottom of a dead-front switchboard. The system is 480Y/277-volt solidlygrounded wye. The building is still under construction, and a number of other tradesare working in the building. The switchboard has already been energized, and it istotally enclosed except for two access covers near the front bottom where the groundbus runs. The ground bus already has the proper number of and size of lugs for theequipment grounding conductors. You ask permission to turn off the main power sothat you can work on connecting the equipment grounding conductors to the groundbus without having to worry about accidentally touching the phase buses…arrow_forward4.a.
