Old Murray to New Murry breaker compatibility

[Ray_G]

Well, I guess the title explains it all... I recently had two older (30 year old) Murray panels replaced with one new 200A / 40 slot panel. I need to add a few circuits, but I wanted to make sure there are no compatibility issues "re-using" the old breakers. As stated, they are all Murray brand.

Thanks,
Ray

Ray shouldnt be any problems "re-using" those breakers.

Where problems arise is when people mix breakers that
are not listed for a specific panel..........gl Ed

From my experience new murray breakers will fit in old panels but old murray
breakers will not fit in new panels.
