Circuit Breaker Test Button Not Working

When a power switch is turned off the electrical potential between the two separating contact points does not die simultaneously a temporary arc of electricity passes between the two contact points.

Circuit breaker test button not working. If the breaker will not trip when the test button is pressed with the load wires connected disconnect the load wires and try again. This test will confirm if the gfci is working correctly or not. Remove the screw that holds the dead front covering the breaker s connections. If it still will not trip with the load wires disconnected replace the breaker.

When a breaker has been tripped whether it s because of pushing the test button on a gfci or afci breaker or because of an overcurrent event the switch moves to the middle position between on and off on newer electric panels.

If the reset button trips again every time you press it there may be a dangerous current leak somewhere on the circuit. If it trips with load wires disconnected the breaker is good.
