How to Fix an Electrical Panel
Step-by-step guide on how to fix an Electrical Panel
Resetting a tripped electrical panel circuit breaker:
-
In the service panel, check the terminals of each circuit breaker to see if any of the switches are leaning in the direction of "off" rather than "on." When tripped, however, the red button on some circuit breakers will pop out.
-
If you discover a tripped breaker, you should turn off or unplug everything in the house that is connected to the circuit that the breaker controls by consulting the circuit index on the inside of the panel.
-
Turn off the power and then back on again at the breaker box. If it trips instantly, you may require an electrician because the problem is likely in the wiring of the circuit.
-
Try turning on lights and other appliances on the suspect circuit to see if the breaker will trip again. Then the gadget itself is broken. A negative response indicates that everything is fine.
Replacing an electrical panel screw-in fuse
-
Verify that the fuse hasn't sustained any noticeable damage. You can visually inspect metal strips within screw-in fuses through a glass; any damage to the strip indicates the fuse has blown and has to be replaced. A shattered metal strip suggests that the circuit was overloaded.
A short circuit, shown by a darkened fuse window, occurs when two or more electrical conductors (wires) come into contact (make a "short") with a third conductor (metal).
-
A blown fuse should be replaced with a new fuse of the same amperage (15- 20- or 30-amp).
Replacing an electrical panel cartridge fuse:
-
Disconnect the power. Pull the cartridge fuse out with a fuse puller.
-
Check the cartridge fuse is working correctly by touching the probes of a multimeter to both ends. The fuse is good if it has a high continuity rating and a low resistance reading. In that case, it has most likely exploded.
-
Use a similar replacement fuse in its place.
Testing an electrical panel circuit breaker:
-
Connect the multimeter's probes to the breaker's terminal screw and a ground. The breaker must be repaired or replaced if the power is out.
-
Get rid of the cover on the electrical service or circuit breaker panel and flip off the primary breaker or switch.
-
Remove the broken breaker from the panel by releasing the screws and keeping them in place. Locate the wires leading to the breaker and disconnect them.
-
Disconnect the old circuit breaker and reconnect the wires into a new one of the same amperage (15, 20, or 30 amps). Connect the new circuit breaker to the wall. (The panel's circuit breakers can either be snapped in or secured with screws.)
-
Turn the power back and inspect the circuit.
