A receptacle shall not supply a total cord-and-plug-connected load in excess of the maximum specified when connected to a branch circuit supplying what number of receptacles or outlets?

The correct answer indicates that a receptacle connected to a branch circuit should not exceed the specified maximum load when it is supplying two receptacles or outlets. According to the National Electrical Code (NEC), the load calculations for branch circuits take into consideration the cumulative capacity of the devices being powered. For a branch circuit supplying multiple receptacles, the NEC establishes guidelines to ensure safety and prevent overloading.

When a branch circuit is designed to supply two receptacles, it allows sufficient capacity to handle the expected load from both devices without exceeding the circuit's rating. This is important in residential applications where multiple devices may be plugged in. If a branch circuit were to supply more than two receptacles, the risk of overload increases significantly, especially if high-wattage appliances are connected simultaneously.

The maximum load specified by the NEC allows for a reasonable amount of flexibility and ensures that the circuit operates safely within its design limits. This threshold is intended to safeguard against overheating and potential circuit failure, making it critical for compliance with electrical safety standards.
