What do "tap conductors" refer to in electrical systems?

Tap conductors refer to the smaller conductors connected to a larger conductor or circuit that are used to supply power to a specific load. In the context of circuit protection, tap conductors are typically smaller in size compared to the main conductors they derive power from. This designation is significant because it indicates that these smaller conductors can still safely carry a portion of the current that the larger circuit can handle, provided they are adequately protected by the appropriate circuit breaker or fuse.

The sizing and protection of tap conductors are dictated by the National Electrical Code (NEC), which provides guidelines to ensure safety and compliance. This is crucial in preventing overheating and potential fire hazards that could arise from using conductors that are not appropriately sized for their circuit utilization.

Understanding tap conductors is important in electrical installations, particularly in branch circuits where distinct loads may require a split from a larger main line. Proper recognition and implementation ensure reliable operation of electrical systems while adhering to electrical safety standards.
