When using the push-in connection method, which characteristic about the conductor size is correct?

The correct characteristic about the conductor size when using the push-in connection method is that it cannot exceed 14 AWG for copper. This is because push-in connections, also known as push-fit or push-to-connect, are designed to accommodate specific wire sizes for secure and efficient connections. In the case of copper conductors, 14 AWG is typically the maximum permissible gauge, ensuring proper electrical contact and minimizing the risk of overheating or connection failure.

Using conductors larger than 14 AWG can lead to inadequate engagement within the push-in mechanism, potentially causing unreliable connections. Also, stranded wires may not fit tightly or securely in a push-in connection when larger than this size, which affects performance and safety.

Understanding the limitations and specific requirements for conductor sizes in push-in connections is crucial for ensuring electrical safety and functionality in any application involving this type of wiring method.
