Has anyone wired for a mini split? I have to rough in for a 1 ton. I was wondering if the indoor unit is powered by the connecting cable that runs from the condensing unit to the blower or does it require a circuit of it's own? It is a GE unit. thanks...
Electure, I've wired Carrier and various other brands. As far as I'm aware (out on a limb here) A/C units use a 5 core cable between the Evaporator and the Condensor unit, size of wire 1.5mm2 in my language. The load is usually only a fan motor and few control circuits at the Condensor end. Allow 8 wires, I will say this.

I have wired a couple recently that were fed with a 15 amp 120v circuit to the outdoor condensor unit. The indoor fan unit was powered by 36v dc supplied from the outdoor unit via a 4 wire 18awg cable.
