What load shall be provided for each 20-amp circuit?

• A. 1,000 VA
• B. 1,500 VA
• C. 2,000 VA
• D. 1,800 VA

Answer: (B)

In residential load calculations, there is a standard credit used for general-purpose circuits that serve receptacles. For each such 20-amp circuit, the load you credit in the calculation is 1,500 VA. This reflects typical usage patterns and provides a practical target for sizing feeders and the service, without assuming every outlet is pulled to its maximum 2,400 VA. The other options don’t fit this common design rule: 1,800 VA would correspond to the full 15-amp circuit capacity, and 2,000 VA or 1,000 VA aren’t the standard dwelling-unit credits for a 20-amp circuit.
