How many receptacles are allowed on a dedicated circuit?

A dedicated circuit is intended for a specific appliance or device that requires a certain amount of power and is not to be shared with other receptacles or devices. This specification is crucial for ensuring that the device operates safely without overloading the circuit.

When a circuit is designated as dedicated, it is typically meant to supply power to one particular load, such as a refrigerator, air conditioner, or other major appliances. Therefore, the National Electrical Code (NEC) generally allows only one receptacle on a dedicated circuit. This ensures that the device connected to the circuit can draw the necessary current without risk of tripping a circuit breaker or overloading the system.

In contrast, multiple receptacles on a circuit can lead to potential electrical issues, including voltage drops and increased risk of overheating if the total load exceeds the circuit's capacity. Therefore, having just one receptacle on a dedicated circuit is both a safety measure and a requirement in many electrical codes.
