How to replace a blown circuit breaker in a distribution box

The basic process is simple in theory: isolate power, remove the panel cover, disconnect the branch conductor from the faulty breaker, remove the breaker, install the correct replacement, reconnect the conductor, and verify normal operation. However, if you choose to replace a circuit breaker yourself, you'll need to know how to find the breaker box, take note of any issues, and replace a faulty breaker to get your power working again. Some homes will have multiple breaker boxes in different places. Replacing a faulty circuit breaker is a common home repair that can restore power to an area of your house without needing an. Replacing a circuit breaker is a task that should only be attempted when the replacement is straightforward, the breaker type is clearly identified, and the person doing the work understands electrical safety procedures. Resetting a breaker is a straightforward task that requires no special skills or advanced knowledge. Expect to pay $10 to $100 for DIY circuit breaker replacement.
