That sounds nice. Albeit, 100a is kinda low for a whole house unless really tiny. *No 14kv inside your meter box. Two 120 hots and the ground supplied by the utility. Granted, it will supply a lot of amperage before deciding you are done. Do you trust that outside breaker more than the main breaker on the box or the same?oh, so i can really piss off the angry pixies, the full 14kv ones.
I actually have an outside shutoff next to the meter. Tis nice, flip a 100a breaker, house is deader than dead.
A double-pole breaker isn't merging anything. It's strictly a space saver doing the same job as two separate without the retardation of having to flip two breakers for one circuit. Which could lead to a deadly accident.
