... But what about the "device type" AFCI? It's in the code, it must be everywhere.
The SqD panel I had was the same can that they would put a 200a breaker panelboard in. There were places drilled and tapped for ground buses. I added one myself.
I always wonder just how much the builder could have possibly saved by using fuses by the time he added 20 "S" adapters and all those fuses. I did end up with a spare pullout since the only 240v thing installed was the A/C unit.
