Reasons to Replace an Old Electrical Panel

Steps for Safely Replacing an Electrical Panel

Once you've hired an experienced, licensed electrician, the key steps involved in safely replacing an outdated electrical panel include:

1. Turn Off Electrical Power

The electrician will locate the main breaker box and shut off power to the entire home. Locking shutoff tags should be placed to prevent accidental re-activation of power during the replacement process.

2. Remove Old Electrical Panel

Next, the existing panel is disconnected from all wiring and removed from the wall. This requires working inside the breaker box, so only trained electricians should perform this step.

3. Install New Panel

The new upgraded panel is secured in place on the wall. It must be installed to meet minimum code requirements for clearance space around it. Proper mounting is vital for safety.

4. Connect Wiring to New Panel

All the home's electrical wires are detached from the old panel and reconnected to the new one. The electrician confirms appropriate connections.

5. Connect Grounding and Bonding

Grounding and bonding connections are made to meet code requirements. This provides shock protection.

6. Attach Breakers and Labels

New circuit breakers are installed and everything is clearly labeled so circuits are identifiable. Breakers must match circuit capacity.

7. Verify Proper Functionality

With the new panel fully installed, the system is tested thoroughly. Breakers are tripped manually to confirm proper operation.

8. Restore Electrical Power

Once operation is confirmed, the main breaker can be turned back on to restore power. The electrician will check outlets and lights.
