1. Turn Off the Power: This is the most crucial step. Turn off the main breaker at your electrical panel. Then, use your voltage tester to verify that the power is completely off at the breaker panel. Test the bus bars to ensure no voltage is present.

2. Access the Main Breaker: Open your electrical panel carefully. Locate the 200-amp Murray main breaker.

3. Disconnect the Wires: Carefully disconnect the wires connected to the main breaker. Take photos or make detailed notes of each wire's location before disconnecting them to ensure correct reconnection. Label the wires if needed.

4. Remove the Old Breaker: Depending on your panel's design, you may need to use a breaker removal tool to carefully remove the old breaker.

5. Install the New Breaker: Carefully install the new 200-amp main breaker, ensuring it's securely fastened.

6. Reconnect the Wires: Connect the wires back to the new breaker in the exact same positions as they were on the old breaker. Double-check your connections and ensure they are secure.
