A plate type grounding electrode shall be installed below the surface of the earth NOT less than _____. a) 24 inches b) 30 inches c) 36 inches d) 48 inches ✔ Ans - B: 30 inches Ref: 250.53(H)

Determine the MAXIMUM allowable ampacity of a size 1/0 AWG THW copper current-carrying conductor installed in a common raceway with three other current-carrying conductors of the same size. Ambilent temperature is 86°F. a) 150 amperes b) 105 amperes c) 112 amperes d) 120 amperes ✔ Ans - D: 120 amperes Ref: Tbl. 310.16; Tbl. 310.15(B)(2)(a) Sol: Size 1/0 AWG THW ampacity (before derating) = 150 amperes 150 amperes x 80% (adjustment factor) = 120 amperes The NEC defines a continuous-load to be a load where the maximum current on the circuit is expected to continue for at least _____ hours or more. a) 3 b) 4 c) 6 d) 8 ✔ Ans - A: 3 REf: Art. 100 Determine the MINIMUM size THW copper branch-circuit conductors required by the NEC to supply a three-phase, continuous duty, AC motor that has a full-load current of 70 amperes. Assume all terminations to be rated at 75°C. a) 1 AWG b) 2 AWG c) 3 AWG d) 4 AWG ✔ Ans - C: 3 AWG Ref: 430.22(A); Tbl. 310. Sol: FLC of motor - 70 amperes x 125% = 87.5 amperes Size 3 AWG THW conductors with an ampacity of 100 amperes should be selected. Given: you have determined a conductor has a computed allowable ampacity of 75 amperes. What is the MAXIMUM standard ampere rating of the overcurrent protection device the NEC permits to protect this circuit? This is

When a feeder supplies a continuous-load of 240 amperes, in general, the overcurrent protection device protecting this circuit shall have a MINIMUM rating of _____. a) 240 amperes b) 300 amperes c) 250 amperes d) 275 amperes ✔ Ans - B: 300 amperes Sol: 240 amperes x 125% = 300 amperes In general, liquidtight flexible metal conduit (LFMC) shall be securely fastened within _____ of each box or other conduit termination. a) 41⁄2 feet b) 3 feet c) 12 inches d) 18 inches ✔ Ans - C: 12 inches Ref: 350.30(A) When a pull box contains conductors of size 4 AWG and larger and a straight pull of the conductors is to be made, the length of the box shall NOT be less than _____ times the trade diameter of the largest conduit entering the box. a) six b) four c) eight d) twelve ✔ Ans - C: eight Ref: 314.28(A)(1) In general, all of the following wiring methods listed are permitted to be used as a feeder for temporary wiring on a construction site EXCEPT _____. a) NM cable b) NMC cable c) type PD cord d) type SJO cord ✔ Ans - C: type PD cord Ref: 590.4(B); Tbl. 400.

Determine the MAXIMUM number of size 14 AWG THHN conductors permitted to be installed in a trade size 3⁄8 inch flexible metal conduit (FMC) that contains a bare size 14 AWG grounding conductor when the flex has external fittings. a) two b) three c) four d) five ✔ Ans - C: four Ref: Tbl. 348. Which of the following listed conduits does the NEC permit to enclose conductors feeding wet-niche underwater pool lights? a) electrical metallic tubing (EMT) b) electrical nonmetallic tubing (ENT) c) galvanized rigid metal conduit (RMC) d) schedule 40 rigid polyvinyl chloride conduit (PVC) ✔ Ans - D: schedule 40 rigid polyvinyl chloride conduit (PVC) Ref: 680.23(B)(2) Underground wiring is not permitted under a swimming pool or within _____ of the pool unless the wiring is supplying pool equipment. a) 10 feet b) 6 feet c) 5 feet d) 8 feet ✔ Ans - C: 5 feet Ref: 680.
