Customer Questions & Answers

will this breaker interchage with GE

Asked by: JIMMY
Hi JIMMY, I can't confirm whether this main breaker conversion kit can be used in a GE panel. It has to be listed on the wiring diagram and would only be listed on Murray panels.

Could I use this breaker to turn a 100 amp breaker to a 200amp

Asked by: Mike
Hi Mike, You would need to check the wiring diagram on your panel which should be on the inside of the door and check if this 200 Amp main breaker is approved for use. The bus bar for the panel that you have would have to be rated for 200 Amps.

200 Amp Main Breaker Conversion Kit is rated 3.2 out of 5 by 5.
Rated 4 out of 5 by from 200 Amp Main Breaker Mine wasn't working. Bought this one. It fit and was an easy replacement.

Rated 1 out of 5 by from The saga of home repair I had to return this part due to the image shown related to what was in the box. even now the image above shows exactly what I needed but what I received was a later version with affixed tabs on the bottom. These would not attach (due to the shape) over the curved ends of the buss bars in the existing service panel. I would have bought a complete replacement service panel when this happened however the time required to wait again for a shipment would be too long due to the damage in the existing panel and my safety concerns. I then drove over to Lowes and bought a complete new service panel and breakers over the counter and made the repairs. Why does Home Depot not stock any service panels???
