Question 1

What is the maximum length of a flexible cord used as a fixed wiring method in a dwelling unit per the 2023 NEC?

Accepted Answer

Flexible cords are not permitted as fixed wiring

Answer

The NEC prohibits the use of flexible cords as a substitute for fixed wiring in buildings under Article 400.12.

Question 2

When sizing conductors for a continuous load, the conductor ampacity must be at least what percentage of the load?

Accepted Answer

125%

Answer

Per NEC 210.19(A)(1), branch-circuit conductors must have an ampacity not less than 125% of the continuous load.

Question 3

A 240V single-phase motor draws 18A at full load. What minimum size THWN copper conductor is required for its branch circuit (continuous load assumed)?

Accepted Answer

10 AWG

Answer

18A × 125% = 22.5A; 10 AWG THWN copper is rated 35A and satisfies the 22.5A minimum requirement.

Question 4

Which conduit type is NOT permitted for direct burial without concrete encasement?

Accepted Answer

Electrical Metallic Tubing (EMT)

Answer

EMT is not listed for direct burial; RMC, IMC, and Schedule 40 PVC are permitted for direct burial per NEC Table 300.5.

Question 5

In a 3-phase 4-wire wye system, what is the voltage between any two hot conductors if the phase-to-neutral voltage is 120V?

Accepted Answer

208V

Answer

Line-to-line voltage in a wye system equals phase voltage multiplied by √3, so 120V × 1.732 ≈ 208V.
