Hello all. I installed 2 new outlets in garage, each on their own circuit (GFCI protected outlets, 12g THHN in conduit). I wanted to use a tandem breaker so that these two outlets were easy to identify in the box. Upon trying to install the breaker, I think that perhaps my box is not compatible with tandem breakers - or I got the wrong breaker. From what I've read, the bus stabs are not notched, so they are not compatible/allowed to be used with tandems.
Just double checking here. I can get the breaker in, but it doesn't seat all the way, so that's wrong. I've got room to put 2 single pole 20a breakers, so it's not the end of the world, just not what I wanted.
