What should the ampere rating be for a single receptacle on an individual branch circuit?

The ampere rating for a single receptacle on an individual branch circuit should be at least equal to that of the branch circuit. This is based on the National Electrical Code (NEC) requirements, which are designed to ensure safety and prevent overcurrent situations.

When a receptacle is connected to a branch circuit, it must be capable of handling the full load that the circuit can provide. If the receptacle's rating is lower than that of the branch circuit, it could lead to overheating and potential fire hazards when the receptacle is used to draw current close to the circuit's maximum capacity. Therefore, having a receptacle with an ampere rating that matches or exceeds that of the branch circuit ensures that it can safely carry the electrical load without risk of failure or hazard.

Other considerations, such as load variation, do not negate the necessity for the receptacle's rating to be compatible with the branch circuit rating. Each receptacle must also comply with specific applications, and factors like circuit ratings are set for safety and functionality.
