A circuit breaker protects the electrical fixtures and connections from overloading and short circuiting. Hence, it is crucial to keep it up and running always. Here's how you can replace it in times of crisis.
For electrical safety in any household, a circuit breaker plays an important role by protecting the fixtures from damage caused due to overloading or short circuits. They are commonly referred to as fuses.
In case of high current levels in any of the electrical wiring, the fuse immediately cuts off the electric flow, so as to prevent further damage. The normal power supply can be restored after fixing the problem.

Instructions for Replacement

While discussing fuse replacement, the first step is to diagnose the problem. By doing so, you can determine whether the fuse really needs to be replaced or not. Many people opt for replacement prior to examining it carefully, stating that it trips off very often. In such a case, the fuse may not be the real problem, it can be the electricity supply.

Identifying the Defect

In order to diagnose malfunctioning, turn off the main power supply, unplug the home appliances, and switch off the lights. Check whether the circuit breaker works after disconnecting the devices. In case it resets, turn on the lights and connect the appliances one by one.
This way you can determine the actual malfunctioning. If that is not the case, press the rest button and switch it on and off, alternately. Always use high-quality fuse to avoid unnecessary tripping.


While replacing a circuit breaker, purchase a superior quality model from the local hardware store. Remove the panel cover by loosening the screws fastened to it. Note the wires and their colors before you start connecting them. Also, make sure that you remember the wires that are connected on the sides.
The next step is dealing with the wires, including the white and the colored ones. To prevent confusion or faulty connections, handle one wire at a time. You can start with the white wire first; unscrew the nut that holds the wire and fasten a wire nut at the tip.
Continue the same procedure for the other colored wires. Once done, exchange the old with a new one and fit it in the right place.
Position the new panel in place of the old one. Make the wire connections in the same way as that of the previous ones, with reference to the colors. Tighten the necessary nuts and screws to secure the wires properly. Remount the panel cover by securing the nuts.
Switch on the fuse to check whether it is functioning or not. You can turn on the lights to check. Nevertheless, if there is no power after switching them on, then you need to call a professional electrician.
