According to the NEC®, what is the minimum computed load for a branch circuit supplying an exterior electric sign?

800 volt amperes
1,000 volt amperes
1,200 volt amperes
1,500 volt amperes

The correct answer is: 1,200 volt amperes

The minimum computed load for a branch circuit supplying an exterior electric sign is set at 1,200 volt-amperes as per the National Electrical Code (NEC®). This specification is crucial because it establishes a baseline for the electrical capacity that must be provided to ensure safe and effective operation of exterior electric signs, which may have varying power requirements based on size and visibility needs. The NEC aims to promote safety and reliability in electrical installations, and by setting this minimum load, it ensures that branch circuits can handle the demands of electric signs without overloading or risking failure. This is especially important in outdoor settings where environmental factors can impact performance. Understanding this requirement is vital for electricians when designing and installing circuits for exterior signage, as it aids in preventing potential electrical hazards and ensures compliance with national safety standards.
