When it comes to planning an electrical distribution system, "bigger
is better" is a good approach.
I'd plan on at least one 2P-40A circuit using #8AWG for a future air
Use 2 gang (4x4) boxes for all receptacles, you will appreciate the
space when it is time to make connections.
I have standardized on 30A locking devices for all 240V equipment
connected with #10AWG wire.
Certainly not required for every machine, but it makes life simple.
