Worked good; wired up shed with 40amps, The breaker has little plastic tabs on the back where it connects to the hot bar that broke off when inserted; I have an older squared panel and the bar is alot thicker. These tabs restricted it from being press all the way in

Hello Kenneth,
I'm sorry the breaker did not work. It sounds like this breaker was possibly not compatible with your panel to begin with, the compatible breaker types should be listed on the inside cover of the panel. If 'QT' is not listed under branch breakers then your Q23040CT2 would not work. Our product selection team could assist with what breakers would work at 866-663-7324 or productselection.us@siemens.com, we would just need the catalog number of the panel you have in the field.

The first breaker I ordered didn't work. Brand new and the breaker would not stay in the on position. The second replacement breaker functioned properly. That was the first breaker in hundreds that didn't work. Quite unusual.

Steve,

I am sorry for the issues. Firstly, are you using a Murray or Siemens panel? They work on both.
If so, you may want to check your panel, and call a certified electrician to make sure everything is ok with it. SIEMENS
