Remove and Install a Breaker

  • Before you can actually tear into the project, you’ll need to find out what brand, type, and size breaker you’ll be replacing. For instance, it may be a Square D®, Homeline, 20 amp breaker that you are replacing. Breakers come in many different shapes and sizes. You should never place a different brand breaker in place of the correct replacement. You may not be able to see a difference, but believe me, there are differences in tension, the way they connect in the holder, and how deeply they mount to the buss.
