What is the maximum number of receptacles allowed on a general-purpose branch circuit?

The maximum number of receptacles allowed on a general-purpose branch circuit, according to the National Electrical Code (NEC), is 12. This regulation is outlined to ensure that circuits are not overloaded, providing a balance between sufficient accessibility for power needs and preventing excessive current draw that could lead to overheating or potential fire hazards.

In residential applications, each general-purpose branch circuit is typically rated for 15 or 20 amps. The NEC allows up to 12 receptacles on a 15-amp circuit under the assumption that these outlets will be used for lightweight devices like lamps or chargers. This rule helps maintain a safe operational load while providing ample outlets for typical household needs.

By adhering to this guideline, homeowners and electricians can ensure that the electrical system is safe and efficient, while also minimizing the risk of overloading circuits, which could lead to tripped breakers or more serious electrical failures.
