Replacing a main circuit breaker is a task that requires careful attention to safety and local regulations. Before you begin, it's crucial to notify your local power company, as they may need to disconnect your service to ensure safety while you work on the breaker. This is especially important if you need to remove the meter, as doing so can be dangerous if the power is still connected.
Once you’ve coordinated with the power company, follow these steps:
1. Turn off all power to your home.
2. Remove the panel cover to access the circuit breaker.
3. Carefully disconnect the wires from the old breaker, noting their placement.
4. Install the new breaker by connecting the wires in the same configuration.
5. Replace the panel cover and ensure everything is secure.
Costs for replacing a main circuit breaker typically range from $150 to $500, depending on the complexity and your location. It's advisable to hire a licensed electrician for this job to ensure it meets local codes and is done safely.
