    Sample questions

    1. Per Article 100, a device whose purpose is to carry or control electric energy as its principal function (but not consume it) is best described as a:

    1. A. Utilization equipment
    2. B. Device
    3. C. Luminaire
    4. D. Appliance
    Show explanation

    Article 100 defines a Device as a component whose principal function is to carry or control electric energy. Utilization equipment converts electrical energy into another form (heat, light, motion); a luminaire is a complete lighting unit; an appliance is utilization equipment for a specific function.

    Ref: NEC Article 100

    2. 125 V, 15 A and 20 A receptacles installed in a dwelling-unit kitchen serving the countertop surface must have:

    1. A. AFCI protection only
    2. B. GFCI protection
    3. C. Both GFCI and AFCI protection
    4. D. No special protection if more than 6 ft from the sink
    Show explanation

    §210.8(A) requires GFCI protection for 125 V, 15/20 A receptacles in dwelling kitchens (and many other locations). §210.12(A) requires AFCI protection for branch circuits supplying 15/20 A, 120 V outlets in kitchens (and most other living areas). Dwelling-unit kitchen countertop receptacles thus require both.

    Ref: NEC §210.8(A) / §210.12(A)

    3. For a single-family dwelling, the minimum size service-disconnect rating is generally:

    1. A. 60 A
    2. B. 100 A, 3-wire
    3. C. 150 A
    4. D. 200 A
    Show explanation

    §230.79(C) requires a minimum 100 A, 3-wire service disconnect for a one-family dwelling. Smaller services (60 A, 2-wire) are permitted for limited installations (e.g., loads under 10 kVA serving very limited equipment per §230.79(A)/(B)).

    Ref: NEC §230.79

    4. The branch-circuit short-circuit and ground-fault overcurrent device for a single continuous-duty motor is sized using:

    1. A. The motor nameplate FLA
    2. B. Table 430.52 percentages applied to the motor full-load current (FLC) values from Table 430.247–250
    3. C. Always 125% of nameplate amps
    4. D. 300% of locked-rotor amps
    Show explanation

    §430.52: branch-circuit short-circuit/ground-fault device is sized by Table 430.52 percentages applied to the motor FLC value from Tables 430.247 (DC), 430.248 (1Φ), 430.249 (2Φ), or 430.250 (3Φ) — NOT the nameplate FLA. Nameplate FLA is used for overload sizing (§430.32).

    Ref: NEC §430.52 / Table 430.52
