Can lighting and receptacles share the same branch circuit?

The correct answer is that lighting and receptacles can indeed share the same branch circuit, but there are important considerations to keep in mind to avoid overloads. The National Electrical Code (NEC) allows for this type of configuration as it can be practical in residential settings where space and resource conservation is important. However, when combining lighting and receptacles on a single branch circuit, one must ensure that the total load does not exceed the capacity of the circuit. This involves calculating the total connected load, taking into account that receptacles can be used for a variety of devices that may draw significant current, especially if they are on the same circuit as lighting.

Although sharing a circuit can be beneficial, the caution advised in the choice highlights the need for awareness of potential issues, such as the risk of tripping circuit breakers or causing overheating. Additionally, it's essential to adhere to typical load calculations to ensure safe operation, which is why careful consideration in this configuration is emphasized in the NEC.
