Is there a limit on how many lighting outlets can be on one branch circuit?

Choosing the option that indicates there is no limit on the number of lighting outlets that can be on one branch circuit aligns with the National Electrical Code (NEC) guidelines. According to the NEC, while there is no specified maximum number of lighting outlets allowed, there are important considerations that must be taken into account when designing a branch circuit.

Primarily, the size of the circuit, the total load that will be drawn from the outlets, and the capacity of the circuit breaker must all be considered to ensure safety and functionality. Most often, a standard 15-amp circuit can accommodate up to 1,440 watts if the circuit is wired with 14-gauge wire, while a 20-amp circuit allows for 1,920 watts with 12-gauge wire.

As a general practice, it is critical to determine the combined load of all the lighting fixtures connected to the circuit to avoid overloading and potential tripping of the circuit breaker. Therefore, in typical residential wiring, it can be practical to have multiple outlets served by the same branch circuit, as long as the cumulative wattage does not exceed the circuit's capacity.

Understanding these guidelines and requirements helps in safely managing the electrical supply in a home, ensuring both compliance with
