Wire Size of outdoor sub panel for multiple ac loads

[Dare]

What size of wire do i need to feed outdoor sub panel to feed 5 condencing units(3-3 ton units and 2-4 ton units). I never use outdoor sub panel for such applications but since distance is around 100' and i have 5 loads it will make a sense to pull one cable and have a sub panel.Thanks

Well before I'd make any conclusive decision on wire size, I'd want to know the true electrical requirements. Using cooling "ton" information is way too vague. Sure it can be done. But you'd have to consider worst case and likely oversize the wire.

For a quick calculation just add up the MCA's of the five units. This will result in a larger than needed feeder but a more involved calculation won't be needed.
