How to Remove a Murray Circuit Breaker

Sebastian Malysa

Circuit breakers are designed to regulate the amount of electricity that passes through a circuit and will automatically shut off electrical supply if any irregularity occurs. Whether you are removing your Murray circuit breaker because it needs to be replaced or is not the right size for the amount of power required for the circuit, removing the circuit breaker is a relatively straightforward procedure. Working with electricity always brings with it a high degree of risk, so if you don't feel comfortable about replacing your Murray circuit breaker yourself, contact a professional electrician for assistance.

  1. Open the Murray circuit panel cover and unscrew it using a Phillips screwdriver. Carefully pull the panel cover away from the circuit board.

  2. Turn off all of the branching circuit breakers first, turning off the main breaker last. Check to make sure the circuit panel has been cut off from electricity and is safe to work on by testing the voltage with a multimeter by touching any two adjacent breakers with the multimeter prongs.

  3. Disconnect the wires from the breaker in need of removal by unscrewing the wire clamps with a flat-head screwdriver and pulling the wires away from the breaker. Move the wires away from the breaker to avoid any potential damage when removing the breaker from its mounting.

  4. Pry the breaker gently out of the mounting, using the flat-head screwdriver. The breaker should slide away from the circuit panel with relatively little force.
