The GFI breaker is designed with a test button incorporated into the breaker itself. Pushing the test button should trip the breaker. ... The test button actually shorts the neutral wireneutral wireDefinitions. Ground or earth in a mains (AC power) electrical wiring system is a conductor that provides a low-impedance path to the earth to prevent hazardous voltages from appearing on equipment (high voltage spikes). ... Neutral is a circuit conductor that normally completes the circuit back to the source.https://en.wikipedia.org › wiki › Ground_and_neutralGround and neutral - Wikipedia feeding the circuit to the neutral bus in the electrical panel creating a ground fault that should trip the breaker.
What does the test button do?
The test and reset buttons are there to make sure the GFCI outlet is in working condition. The last thing you want is for something to be wrong with the outlet, which in turn could remove the safety mechanism that can help prevent deadly shocks from occurring should you accidentally get an electronic device wet.May 29, 2017

How does a push button circuit breaker work?
A push button switch is a small, sealed mechanism that completes an electric circuit when you press on it. When it's on, a small metal spring inside makes contact with two wires, allowing electricity to flow. When it's off, the spring retracts, contact is interrupted, and current won't flow.Mar 13, 2018
