thanks! I’ll take your advice and put a bead at the top.Fine mount. Water does not go up and you probably used a knock out hole, so didn't have to disturb too much wiring. Still, do what you can to put a seal at the top so water does not find the mounting holes.
What did you end up with for the branch breaker?
I ended up just moving two of the AFCI circuits to the sub panel. That was easier than trying to unbundle all the wires to find the right neutral to move to the sub panel (to go with the hot I was relocating. Saved me $100 too, by not having to buy those two circuit breakers. Appreciate your help!
