The most common way to reset a power circuit that has stopped working is by resetting the tripped circuit breaker in your electrical panel.
When a power circuit experiences an overload or a short circuit, a safety device called a circuit breaker "trips" to interrupt the flow of electricity and prevent damage or fire. Resetting the circuit involves resetting this tripped breaker.
Steps to Reset a Tripped Circuit Breaker
Follow these steps carefully to restore power to a tripped circuit:
-
Locate the Electrical Panel: Find the main electrical panel in your home or building. This is usually a metal box often located in a basement, garage, closet, or utility area.
-
Identify the Tripped Breaker: Open the panel cover. Look for a breaker switch that is in a different position than the others. While most "on" breakers point towards the center of the panel, a tripped breaker is often in an intermediate position, sometimes slightly towards the "off" side, or might be fully "off."
-
Reset the Breaker: As described in the reference, you cannot simply flip a tripped breaker back to the "on" position immediately. You must first ensure it is fully "off":
- Push the breaker switch all the way to the off position until it clicks.
- Once it has clicked into the full "off" position, you can then turn it back to the on position.
This process properly resets the internal tripping mechanism within the breaker.
-
Check the Circuit: After resetting the breaker, check the lights, outlets, or appliances that were affected to see if power has been restored.
What to Do if the Breaker Trips Again
If the breaker trips again immediately or shortly after being reset, this indicates that the underlying problem (overload, short circuit, or faulty appliance) still exists. Continuing to reset the breaker without addressing the cause can be dangerous. In this situation:
- Unplug appliances or devices from the affected circuit.
- Turn off lights on the circuit.
- Attempt to reset the breaker again.
- If it still trips, there is likely a more serious issue, and you should contact a qualified electrician to investigate.
Understanding how to safely reset a circuit breaker is a fundamental part of managing your home's electrical system when minor issues occur.
