According to NEC, what is the required VA per square foot for general lighting load in residential occupancies?

The correct value for the required VA per square foot for general lighting load in residential occupancies is 3 VA/sq ft, as specified by the National Electrical Code (NEC). This standard is established to ensure that sufficient electrical capacity is allocated to lighting in residential buildings, taking into account factors such as the number of fixtures, the wattage of lights, and user behavior.

By setting the requirement at 3 VA per square foot, the NEC provides a guideline that helps electricians and designers calculate the appropriate load to design and install electrical systems safely and efficiently in residential spaces. This value is crucial for planning circuits to avoid overloading, ensuring user safety, and improving energy efficiency. Understanding and applying this standard is essential for compliance with regulatory electrical safety codes in residential projects.
