Blowing a fuse or tripping a circuit breaker is a relatively common issue, especially if you run many items off the electric supply at one time. If you overload a circuit, your system will cut off the electrical flow to prevent circuit damage or a fire. Follow these steps to restore power and get those appliances going again.
- Turn off all lights and unplug a few appliances in the room or rooms that have lost power. – Check a new appliance, it may likely be the cause of the overload!
- Locate and open your electrical panel. – Can often be found in a basement, hallway or utility room.
- Always use caution. – If you are unsure what to do contact a qualified electrician.
- Look for a breaker that has moved from the “on” position. – This will restore power.
- Check each fuse to see if the piece of metal inside has melted. If your electrical panel has fuses, check each fuse to see if the piece of metal inside has melted, or if the glass window at the top of the fuse has become discolored.
- Test your new fuse. Plug in one or two electrical appliances and turn them on to test your new fuse or reset breaker. If the outlet loses power again, it’s possible that you are using too many amps for the fuse or breaker, and need to move some appliances around.
