Question: 1 / 400

In residential occupancies, the NEC requires how many VA per square foot for the general lighting load?

2 VA/sq ft

3 VA/sq ft

In residential occupancies, the National Electrical Code (NEC) specifies a general lighting load of 3 volt-amperes (VA) per square foot. This requirement is established to ensure that electrical installations can safely handle the expected lighting demand, providing adequate power without overloading circuits.

The basis for this standard comes from historical data on how much energy is typically required to light residential spaces adequately, considering various factors such as room size, the number of light fixtures, and the types of light sources used. By adhering to this 3 VA/sq ft guideline, electricians and builders can design systems that not only meet safety standards but also align with typical residential lighting needs.
