ECN Forum Forums General Topics of the Trade General Discussion Area What breakers fit old ITE G2040MB1200 panel

I know Siemans bought out ITE but can I use any Siemans breakers in this panel or do I have to find old breakers online somewhere to buy. I need two single pole 20amp breakers to finish a job.
Thanks so much.

Siemens is the successor to ITE, so yes, but I have not seen anything allowing Murray/Siemens breakers to be used even though they are the same breaker, just to add a bit.

Thanks so much for the info. Appreciated!!
I heard back from Siemens and they verify to use the Q120 breaker. Last time I sent them an email they never replied but got lucky this time.

Last I heard the Siemens Q120 and the Murray MP120 came from the same assembly line. The only difference is the barcode label and the Q or MP

They are both the old Gould/ ITE design from the late 1970's, but have never have seen any paperwork saying it is OK to interchange them.
