Question: I have a friend whose mother-in-law's main breaker burned up, due to a loose connection. We had PG&E come pull the meter so I could replace the bad breaker. There was only minor damage to the buss bar, I pulled all the breakers out of the panel and cleaned the bars of any carbon deposits. I replaced the damaged breaker (GE, I believe) with a similar breaker (Homeline), which was the only suitable replacement I could find in our town without buying a full load center. PG&E came out to replace the meter, then pulled it back out. A customer service rep called my friend (who owns the house) to tell him that "according to the notes" she has, that I used the "wrong breaker." That was all the detail she could give us. Any idea what they're looking for here?

Possible Reasons for PG&E's Concerns



Incompatible Breaker Type

Homeline breakers may not be compatible with the GE panel. Different manufacturers have specific requirements for the type of breakers that can be used in their panels.


Breaker Not UL Listed

The Homeline breaker may not be UL Listed, meaning it has not undergone rigorous testing and met safety standards. PG&E requires breakers to be UL Listed for safety reasons.

Wrong Amperage Rating

The Homeline breaker may have a different amperage rating than the original GE breaker. Using a breaker with an incorrect amperage rating can create safety hazards.


Circuit Misconfiguration

The replaced breaker may not be protecting the intended circuit correctly. There may be a mismatch between the breaker rating and the circuit it is protecting.

Panel Incompatible

The Homeline breaker may not fit properly or make good contact with the buss bars in the GE panel. This can lead to overheating and electrical issues.


Local Code Violations

PG&E may be concerned about compliance with local electrical codes. Replacing the breaker without proper authorization or using non-approved components may violate local regulations.

Steps to Take:
Contact PG&E and ask for clarification on their concerns. Verify that the Homeline breaker is compatible with the GE panel. Check that the breaker is UL Listed. Ensure that the breaker amperage rating matches the circuit it is protecting.* If necessary, consult with a licensed electrician to inspect the panel and ensure proper installation and compliance with codes.
