What is a key characteristic of tap conductors in relation to their protection?

The key characteristic of tap conductors is that they are defined as being smaller than the size required by the breaker. This means that tap conductors can be used to deliver power to specific devices or loads, but they are intentionally sized smaller than the conductors that are directly fed from the breaker. The National Electrical Code (NEC) outlines specific provisions for tap conductors to ensure proper protection and reduce the risk of overheating or failure.

The logic behind this characteristic is that tap conductors are intended to carry the load for a limited distance, and maintaining a smaller gauge allows for flexibility in design while ensuring that the circuit is adequately protected. However, it's important for electricians to adhere to code requirements regarding the maximum length and the specific installation methods to ensure safety and compliance with applicable standards.
