Sample Practice Questions for Branch Circuit & Feeder Load Calculations

  1. Question 1Ref: NEC 220.55 — Load Calculations: Household Electric Ranges

    A dwelling unit has a 240-volt, 12-kW electric range. Using the standard calculation method, what is the demand load for the range?

    Show Answer & Explanation

    Correct Answer
    C. 8.0 kW

    Table 220.55, Column C: for one household range rated not over 12 kW, the standard-method demand load is 8 kW. The 12 kW nameplate is not used directly, and Note 1 (5% per kW over 12 kW) does not apply to a 12 kW range.

  2. Question 2Ref: NEC 220.82(B) — Optional Calculation: Dwelling Unit General Loads

    A dwelling has four 120V, 20-amp branch circuits for general lighting. Using the optional calculation method, what is the demand load for the general lighting in VA?

    Show Answer & Explanation

    Correct Answer
    D. 9,600 VA

    Four circuits × 120 V × 20 A = 9,600 VA. Under the optional method in 220.82(B), the general loads are taken at 100% for the first 10 kVA and 40% for the remainder. 9,600 VA is under 10 kVA, so the full 9,600 VA applies.
