5.a. The labor performed when you extend an existing electrical system is called A. old work. B. repair work. C. troubleshooting D. faultfinding. 5.b. The basement in an existing building has concrete walls, a concrete floor, and a concrete ceiling. From this information, you know that receptacles, lamp fixtures, and switches A. can't be installed in this basement as there is no way to ground the circuit. B. won't require ground-circuit protection because concrete insulates the occupants from ground. C. can be installed in the basement and circuit wiring enclosed in a surface raceway system. D. can only be installed if they're connected with armored cable.
