What brand circuit breakers are listed to be installed in a stab in Murray panel?
What brand circuit breakers are listed to be installed in a stab in Murray panel?
Siemens or Murray are both listed for Murray as it's identical equipment.
Cal an OFFICIAL Siemens or Murray distributor, they can get you a letter from Siemens that will state this. But be aware, a lot of distributors SAY they are one but are buying through someone else and will not get a call back from a Siemens office. Don't take no for an answer, keep pushing until someone finds it to get you off their back. I used to be the guy at a local Siemens office who sent out those letters, I know for a fact that they exist.Do you have any documentation that shows they are both acceptable? I have never seen a Murray panel list Siemens type Q breakers or a Siemens panel list Murray type MP breakers. While you and I know they are the same breaker with different stickers an inspector could create a stink.
Westinghouse did the same thing when they purchased Challenger. Same breakers and load centers with different stickers but the breakers were not supposed to be used interchangeably. When Eaton purchased Westinghouse they merged the lines with one breaker listing both type BR and type C.

how about an industry standard architecture 1" plug on breaker!?
Also I had to buy both some Murray & Siemens breakers and they both had the same numbers.
I was sending that letter out up until 2006, so I know it's not just after 2104. IIRC the letter was actually dated 1996 or something like that. It was released after Siemens had bought Murray in an attempt to satisfy AHJ requests for proof that they were one and the same.Siemens circuit breakers are listed for use in Murray panelboards manufactured after October 2014. The panelboard label and installation instructions will list the type of Murray and Siemens breakers that are suitable for use in said panelbaord.
A letter confirming the same can be obtained from:

Sometimes I wish I had kept a copy of that letter, I could sell it...If / when someone gets a copy of this "Letter" from Siemens please share it here, I would like to keep a copy on file.
Thanks!
Not all 1 inch breakers fit all 1 inch type panels. Some panels have rejection stubs. I am not referring to CTL panels.
Right I never said they did. Homelike is an example. But that is my point that it would be great if the industry would get its head out of its @$# and have standardized 1" breakers.
Murray panels show to use "Murray Type MP Breakers. Siemens panels show to use "Siemens Type Q Breakers"
The Murray and Siemens breakers are the same except for the stickers but they are not the same part number.
