@raratt to make it more fucked up.
Eaton/cutler hammer type panels that take BR breakers they have two different types now. A plug on type which is newer. The neutral is also brought down in between the buss bar and where the breakers clip in. Those BRP afci breakers click on to that extra neutral bar, simplifying the wiring in the panel. You don’t need to run the hot and the neutral to the breaker AND and the white curly wire off the breaker to the neutral bar like the “older” ones
those breakers are fucking impossible to source right now. You can still use the other ones on the newer eaton panels though. I’m still trying to score those older ones. Fucking covid.
