What is the general lighting load demand for a residential service?

The general lighting load demand for a residential service is defined by NEC (National Electrical Code) standards, which establish guidelines for calculating electrical loads. For a residential service, the standard demand is set at 3 volt-amperes (VA) per square foot. This figure is used to ensure that there is a reliable capacity for lighting in homes, factoring in the typical design of residential spaces and their usage patterns.

Utilizing this standard load allows for adequate provision of power for lighting fixtures in typical residential applications, ensuring safety and efficiency in the electrical system. It's essential to adhere to these guidelines to maintain compliance with code and to ensure that the electrical installation can handle the expected load.
