Friction type connectors on pigtails may be used if the circuit is rated not more than how many amperes?

Friction type connectors, also known as push-on connectors, have a specific amperage rating for safe usage in electrical circuits. When it comes to pigtails, which are short wires with connectors used to facilitate connections, the maximum rating for using friction type connectors is 20 amperes. This rating is crucial because it helps prevent overheating and potential electrical failures that could arise from excessive current flow. Using connectors above this rating could lead to insufficient contact integrity, resulting in connection issues or electrical fires.

The 20-amp maximum allows for a balance between usability and safety, ensuring that the connectors can handle common electrical loads while maintaining the integrity of the electrical connection.
