SECTION ONE: QUESTIONS 1–100
1. What is the maximum number of disconnects
permitted for a single service, provided they are
, grouped in one location?
A. Two
B. Four
C. Six
D. Eight
🟢 C. Six
🔴 Explanation: Per the NEC, a service is permitted to
have no more than six switches or circuit breakers
mounted in a single enclosure or a group of separate
enclosures.
2. A continuous load is one where the maximum
current is expected to continue for how many
hours or more?
A. One
B. Two
C. Three
D. Four
,🟢 C. Three
🔴 Explanation: The NEC defines a continuous load as
any load where the maximum current is expected to
continue for three hours or more.
3. Which of the following is the minimum size copper
grounding electrode conductor for a 200-ampere
service using 3/0 AWG copper conductors?
A. 8 AWG
B. 6 AWG
C. 4 AWG
B. 2 AWG
🟢 C. 4 AWG
🔴 Explanation: Based on Table 250.66, for 3/0 AWG
copper service-entrance conductors, the minimum size
copper grounding electrode conductor required is 4
AWG.
4. In a commercial kitchen, which of the following is
required for all 125-volt, single-phase, 15- and 20-
, ampere receptacles?
A. AFCI protection
B. GFCI protection
C. Tamper-resistant covers
D. Twist-lock configurations
🟢 B. GFCI protection
🔴 Explanation: The NEC requires GFCI protection for all
125-volt, single-phase, 15- and 20-ampere receptacles
installed in kitchens, whether or not they serve
countertop surfaces.
5. A 240-volt, single-phase heater has a nameplate
rating of 4800 watts. What is the current draw?
A. 10 amperes
