Sample 1 — Wiring Methods and Materials
Question: According to the NEC, noncombustible surfaces that are broken or incomplete around a cabinet shall be repaired so there will be no gaps or open spaces greater than ______ at the edge of the cabinet or cutout box employing a flush-type cover.
- A. 1/16 in.
- B. 1/8 in.
- C. 1/4 in.
- D. 3/8 in.
Correct Answer: B
According to the National Electrical Code or National Electrical Code Handbook (Page 285), Section 312.4, noncombustible surfaces that are broken or incomplete shall be repaired so there will be no gaps or open spaces greater than 3 mm (1/8 in.) at the edge of the cabinet or cutout box employing a flush-type cover.
Reference: NEC 2017 Section 312.4
Sample 2 — Branch Circuits and Conductors
Question: What is the minimum copper service-entrance conductor size for a 200 A, 120/240-volt, single-phase service to a one-family dwelling, using THHN conductors with 75°C terminals?
- A. 2/0 AWG
- B. 3/0 AWG
- C. 250 kcmil
- D. 300 kcmil
Correct Answer: A
For a 120/240-volt, single-phase service supplying the entire load of a one-family dwelling, 310.12(A) (310.15(B)(7) in NEC 2017) permits service conductors with an ampacity of not less than 83 percent of the service rating: 200 A x 0.83 = 166 A. In the 75°C column of Table 310.16, 2/0 AWG copper is rated 175 A, so 2/0 AWG is the minimum. Without that dwelling allowance, 3/0 AWG copper (rated 200 A) would be required.
Reference: NEC 2017 Section 310.15(B)(7) and Table 310.15(B)(16)
Sample 3 — Equipment and Devices
Question: A fixed storage-type water heater with a 50-gallon capacity is marked 4500 watts at 240 volts (18.75 amperes). The branch-circuit device and assembly are not listed for operation at 100 percent of rating. What is the minimum branch-circuit rating permitted for this appliance?
- A. 25 amperes
- B. 30 amperes
- C. 35 amperes
- D. 20 amperes
Correct Answer: A
NEC 2017, Section 422.13 requires a fixed storage-type water heater of 450 L (120 gal) or less to be considered a continuous load, and 422.10(A) requires the branch-circuit rating for a continuous-load appliance (other than motor-operated) to be not less than 125 percent of the marked rating. 18.75 A x 1.25 = 23.44 A, so the next standard rating of 25 A (NEC 240.6(A)) is the minimum permitted.
