What is the limit on the number of lighting outlets permitted on one branch circuit?

The limit on the number of lighting outlets permitted on a single branch circuit is not specified, meaning there is no imposed limit. In residential wiring, the National Electrical Code (NEC) does provide guidelines regarding the safe and effective installation of electrical systems, including branch circuits. However, lighting outlets can be wired on a single circuit without a maximum count as long as the circuit is adequately rated to handle the total load.

It is important, however, to consider the overall load on the circuit, ensuring it does not exceed the circuit’s ampacity. When planning lighting circuits, it's crucial to balance the load and assess the demands based on the fixtures and bulbs used, but technically, as long as the load is managed appropriately, there is no limit to the number of lighting outlets on a branch circuit. This approach allows for flexibility in wiring design for residential spaces.
