An electrician must install branch-circuit conductors in a metal raceway that will supply a 120/240-volt electric range. The grounding conductor. How many conductors raceway will not be used as the equipment- I must the electrician install? What would be the colors for the required conductors? (Objective 12-7) 11. Name the article in the NEC® that covers LFMC. (Objective 12-1) 12. When installing more than two conductors in a conduit or tubing, what is the maximum percentage of fill that is allowed by the NEC? (Objective 12-1) 13. An electrician must always install an equip- ment-grounding wire along with the regu- lar circuit conductors in RMC, IMC, and EMT. (Circle the correct response.) True or False (Objective 12-1) a 14. Expansion fittings are required for PVC con- duit to compensate for thermal expansion and contraction when there is expected to be inch or greater length change in a straight run of the conduit. (Objective 12-1) 15. A nonconductive fish tape should be used when pulling conductors though an installed conduit system and into an energized load- center. (Circle the correct response.)
