What is the minimum rating required for a single receptacle on an individual branch circuit?

The minimum rating required for a single receptacle on an individual branch circuit is 100 percent of the receptacle's rating. According to the National Electrical Code (NEC), this specification ensures that the receptacle can handle its full load capacity safely without risk of overloading the circuit. For instance, if you have a 20-amp receptacle, the branch circuit must be capable of supplying that full 20 amps. This requirement is crucial for maintaining safety and reducing the risk of overheating or circuit failure, which could lead to a fire hazard.

The other options present percentages that do not meet the NEC standards, as they suggest that a receptacle can operate at less than its capacity, potentially leading to unsafe conditions if the receptacle is used to its full ability without the necessary circuit support. 100 percent ensures that the circuit can accommodate any load devices connected to it without exceeding capacity limits.
