In order to replace a common household circuit breaker that is housed in a regular 2-pole main breaker with branch circuit compartments, you would first turn off all of the branch circuit breakers and then the main circuit breaker. Never assume the breakers are off; you need to check for voltage on adjacent breakers to make sure the breaker panel is dead.
Next, take off the panel cover. This will give you access to branch circuit breakers but not the main breaker compartment. Do not attempt to remove the cover to the main breaker; this should only be accessed by a certified electrician. You can replace the circuit breaker by just removing the panel cover.
Once you have removed the cover then you can disconnect the wire from the faulty breaker and pull it out of the way. Now, carefully pry the defective circuit breaker out of its position. Take note of how the breaker fits in the panel and locks into position so that you can put the new circuit breaker in correctly. Upside down and sideways positions typically do not work. Next, insert the new circuit breaker.
While you have the circuit panel open, check the other branch circuits to make sure they are properly in place and tighten any loose parts. Put the panel cover back on and make sure all the branch circuit switches are in the “off” position. Proceed to turn on the main circuit breaker and then flip on each individual branch breaker separately. Test the circuits to make sure they are working properly and stay set.
If the replacement circuit is working right then you are finished. If you still have a circuit problem then you may want to check the electrical devices associated with the circuit or consult a professional for further assistance.

When you are working with electricity it is extremely important to see all of the wires and objects associated with the area that you are working in. One touch of a live wire is all it takes for a fatal accident. Make sure you have the right gear to do the job correctly.
In order to purchase the right kind of circuit breaker replacement, you'll need to get the model number and other information off of the old circuit breaker or check to see if the information is located inside the breaker panel box. Always remember to disconnect power when opening the breaker box or working inside it. The breaker box itself should not pose as a electrocution risk, but you can never be too cautious. The wires inside the circuit breaker are “live,” so you should not attempt to remove the breaker if you are not sure that the wires are dead. Electrocution can be fatal, so if you are not sure how to change the circuit breaker then you should consult a professional before proceeding.
Black and red wires are typically “hot” meaning they have electrical current. They carry the electricity from the circuit breaker to the appliance or electrical fixture.
White wires are electrical return wires. The electricity will flow through the appliance or fixture back to the circuit breaker.
Electrical current should not be running through the ground wire unless there is a short circuit and if this is the case then the breaker will flip killing the electrical current immediately. The ground wire is typically bare and attaches to the appliance frames.
The only place where white and ground wires connect is at the bus bar on the circuit panel.
Becoming familiar with the wiring basics and educating yourself about the inner workings of your electrical system will help you stay safe and prevent miswiring and other electrical related mistakes. Before you attempt circuit breaker replacement you need to know what each wire does and make sure you have them connected properly.

A new circuit breaker is a must. Make sure that you have the proper brand and size in order fit properly and work right.
Quality circuit breakers should last a long time. Every electrical problem or short circuit is not necessarily caused by the circuit breaker device. The trouble could be coming from somewhere else, so you should exhaust all other options before blaming the circuit breaker for every problem that occurs.
If you are not sure what is causing the circuit breaker to trip often and you are not able to pinpoint the problem then it is a good idea to consult a professional for assistance.
If the bus bar is damaged then the problem will not be solved by just a circuit breaker replacement because the bus bar will continue to cause arcing trouble with the new breaker. A permanent fix in this situation is to fix the bus bar.
A circuit breaker can still have hot wires or live current even when there is trouble with a certain wire. Circuit breakers provide protection against forceful currents. Shorts and other circuit problems are typically not linked to the circuit breaker unit so you will need to look elsewhere to solve that kind of problem.

Do not exceed the wattage limit on light bulbs or appliances if an appliance continues to blow a fuse or flip the circuit breaker then it should be repaired or replaced immediately. An electrical short in an appliance cord can be dangerous to everyone in the home.
Use safety precautions when repairing or replacing any type of electrical equipment such as fuses, circuit breakers, cords, wires, etc. If you are not knowledgeable about the process and procedure of electrical repair, you should consult a professional. Don’t try to fake it; you'll probably end up regretting it if you do.
The main advantage to circuit breakers is that they can be reset and circuit breaker replacement is almost never necessary. A fuse has to be replaced each time it blows because of the way fuses are designed. In a fuse, electrical current runs across a soft metal wire. The fuse wire is designed so that any load over the maximum will cause it to overheat and melt. When the wire melts, electricity can no longer run across it and the circuit is broken. Fuses will not fail you as long as they are sized correctly for the circuit.
Today fuses are becoming obsolete and being replaced with circuit breakers, but if you move into a house with a fuse box don’t be alarmed; you are still in good hands with the circuit protection of the fuse.
