If you suspect a malfunctioning breaker, here’s a simple test to check:
- Turn off all devices connected to the circuit.
- Switch the circuit breaker to the “off” position.
- Using a voltage tester or multimeter, check the breaker’s terminals for voltage. If voltage appears when the breaker is off, it might be defective.
- Turn the breaker back on and recheck the terminals. If no voltage is detected while the breaker is on, it’s likely faulty.
These steps can help identify potential issues with a circuit breaker. For more detailed guidance, visit the Faulty Circuit Breaker page.
