The general lighting load of a retail store per NEC Table 220.42(A) is _____.

Explanation:
The idea here is to size lighting for a service or feeder using a standard per-square-foot value from NEC. For a retail store, the general lighting load is 1.9 VA per square foot. So you multiply the floor area by 1.9 to get the total lighting load in volt-amperes. This simplified method reflects typical lighting demands and is based on how the NEC groups occupancies for service calculations. In practice, you’d use this generalLighting load alongside other loads (non-lighting equipment, motors, etc.) to size the service. For example, a 2,500 ft2 store would have a general lighting load of 2,500 × 1.9 = 4,750 VA.
