What is the minimum VA load for exterior signs or outline lighting, according to NEC?

The minimum VA load for exterior signs or outline lighting, as specified in the National Electrical Code (NEC), is set at 1,200 VA. This requirement is in place to ensure that the electrical systems providing power to these fixtures can handle the load reliably and safely. The necessity for a defined minimum helps mitigate issues such as under-sizing conduits or feeders, which could lead to overheating or voltage drops during peak usage.

The 1,200 VA standard is designed to accommodate the varied and often unpredictable electrical demands of such lighting systems, ensuring they function properly under different conditions. Users will find that maintaining this standard contributes to the longevity and safety of their lighting installations, which is particularly vital for exterior applications that may be exposed to environmental factors.

Understanding this NEC specification is crucial for anyone involved in designing or installing electrical systems for exterior signs, as it lays the groundwork for proper planning and execution.
