I'm a complete newbie to this so I have a few questions...
1) Gauge of wire from panel to exterior subpanel? I know it's two live from a 220V breaker and neutral, also do I need GFCI, or a standard breaker is fine, 30amps good?
2) Conduit, hard or flex, and composition of conduit? I would prefer hard, also any restrictions on height when running on exterior of house, obstacles of windows & Main line in the way, how to avoid? Can I push away from the wall with a treated two by four or do I have to route away?
3) Do I need a subpanel outside? Does it need to be fused? Any distance / placement requirements to ground level, windows, ac condenser unit, ac pressured lines?
Thank you for taking the time to respond to my questions.

Yes, the exterior subpanel is on the same physical building on a different side of the house feeding from behind the house.
