What is the maximum size conductor permitted for devices that use the "push-in" connection method?

The correct answer is that the maximum size conductor permitted for devices that use the "push-in" connection method is 14 AWG copper. Push-in connections are designed for easy and quick installation; however, they have limitations on the size of the wire that can be safely and effectively used.

In general, the push-in method can accommodate smaller gauges of wire, typically up to 14 AWG for copper conductors. This approach helps ensure that the connection can be maintained securely without risking loose connections or overheating. Using larger gauge wires, such as 10 AWG or 12 AWG, can exceed the capacity of the push-in connectors, potentially leading to safety hazards.

140 AWG has the right balance of size and compatibility for the push-in method, ensuring adherence to safety standards while promoting efficiency in electrical installations. It's crucial for those working with electrical systems to be aware of these specifications to ensure compliance with electrical codes and to maintain the safety of the installations.
