Do you want to know how to replace the circuit breaker? Are you looking for some simple steps to replace the circuit breaker? If so, then you have come to the right place. Replacing the circuit breaker requires several safe and simple steps. In addition, you must also use some tools.
The function of the circuit breaker is to interrupt the power supply of the circuit when the flow exceeds the safety limit. When the circuit breaker is not working, it prevents the power supply to the switch and others from reaching the socket. In this case, consider circuit breaker repair. When the damage cannot be repaired, the circuit breaker can also be replaced.
Below we will introduce the reasons for the circuit breaker tripping. In addition, we will know how to replace the circuit breaker. In addition, you will learn about the tools that can be used during the replacement of the circuit breaker.
1. Causes of circuit breaker tripping
The MCB in the MCB monitors the current level of the circuit. If the circuit breaker senses that the current is insufficient or greater, it will automatically shut down to prevent power interruption. Its purpose is to prevent the circuit from overloading. When it comes to circuit breaker tripping, it can happen due to many factors.
When you operate many electrical appliances at the same time, the circuit breaker may trip. However, if the circuit breaker trips, you can reset it. If the circuit breaker is damaged, you have no choice but to replace it.
In addition, if the circuit breaker continues to trip after reset, you may need to replace it. You can check with an electrician to know the exact reason. Professionals can consider replacement or maintenance according to the situation.
2. Tools required to replace the circuit breaker
If you want to replace the circuit breaker yourself, you need some tools. Without safety tools, this process will be dangerous. Therefore, before considering replacement, make sure you have all the safety tools ready. You will have to use insulated tools because you will work with electricity. Here are some tools you can repair or replace the circuit breaker.
- When replacing the circuit breaker, you need a rubber pad or plywood pad.
- Prepare an insulated flashlight to ensure the required lighting during the entire process.
- Wear goggles to protect your eyes in harsh environments.
- Prepare some other insulating tools, including wire strippers, hammers, and screwdrivers.
- Make sure you have a voltage tester to test whether the new circuit breaker is working properly. In addition, you will have to make sure that there are no live wires when working with electricity. Any error can be fatal.
- You will have to get a cable connector to connect the circuit breaker to the panel.
In addition to these, you also need a new circuit breaker. When buying a circuit breaker, you must check its size and brand to make sure it fits. If you want to buy electronic equipment from well-known companies, you can consider Chint. There are many products to choose from.
It will be easier to replace the circuit breaker once you have all the required tools. Here are step-by-step instructions.
3. How to replace the circuit breaker
If you want to replace a circuit breaker in your two-pole circuit breaker, first, you have to turn off all the branch circuit breakers, and then you can turn off the main circuit breaker. You will have to check again, and then you can plan the next step. You will have to check the adjacent circuit breaker to make sure the power supply has stopped. Any mistake can cause irreparable emotional damage.
Once you are sure that the panel is closed, you can remove its lid. After removing the panel cover, you can enter the shunt circuit breaker. There is no need to remove the main circuit breaker cover. This is risky and can only be handled by professionals. However, you can replace the circuit breaker by removing the panel cover.
Now you must remove the wires from the broken circuit breaker. Then you can pull out the circuit breaker. You have to be careful about this. When disassembling the old circuit breaker, you must observe its position and installation. Check the machinery and accessories so that the new circuit breaker can be installed in the damaged place smoothly. After removing the fault circuit breaker, install a new circuit breaker.
Check the installation and location of the new device. At the same time, observe other circuits and tighten any loose connections. Close the panel cover to turn on the main circuit breaker and other circuit breakers. Use a voltage checker to ensure all functions.
4. Safety requirements when replacing
When using electricity, safety should come first. It is worth mentioning that there are some electrical appliances in the circuit breaker box. Therefore, you must take the necessary safety measures and use the right tools to work in and around these boxes. First, take the safety tools, and then you can start working.
In addition, adequate lighting is required when replacing the circuit breaker. You can use an insulated flashlight. But when installing the circuit breaker, you must hold it with one hand. Therefore, you must find a better solution. You may consider using independent lighting equipment. In addition, you have to make sure that all circuit breakers are closed.
You can safely replace the circuit breaker in accordance with appropriate safety measures. In addition, you will have to choose the appropriate size for the new circuit breaker to ensure a proper fit. When replacing, make sure you have a safety device to protect it. The most important thing is to close all circuit breakers, including the main circuit breaker. If you are not confident, you can go to an electrician.
