Changing a circuit breaker is one of those tasks which you can do yourself without having to call an electrician – however, you should be very careful when you change a circuit breaker as it is potentially highly dangerous and you can hurt yourself badly if you receive an electrical shock. When you are going to change a circuit breaker, the first thing that you need to do is turn off the main power to the house. Make sure that the main power switch for the house is turned off and that nothing electrical in the house is running, or the high voltage, high amperage current for the house might kill you.

Next, you should be sure to have the right kind of circuit breaker with you – circuit breakers which are commonly used are Siemens circuit breakers, Cutler Hammer circuit breakers and Square D circuit breakers. What you should try to get are the exact same brand and style of circuit breaker that you see in the box. If necessary, take out the offending circuit breaker (make sure to turn the house power off first!) to the store so that you can match it up and get one which fits.

Get the right amperage of circuit breaker so that you do not experience frequent short-outs or overloads, one of which is annoying and the other one of which is highly dangerous. Always replace a circuit breaker with the exact same one and keep a mind towards safety and you will be able to protect yourself while fixing the electrical system of your home.
