2 4ton cac units 125' from panel.

I'd pull # 2/3 SER AL., just to cover my ass and charge accordingly because the specs were not present. Plus this gives options later on when they need to add something. Win/Win in my book. I bet i come out cheaper than the copper you propose to run.

Sure, why not? Set a little sub panel and maybe not even need any disconnect other than the breakers. There is probaby a service receptacle needed if there isn't already one there.

And one day the may need to power a pole light or fountain or who knows what. I'm starting to like SER AL since the price of copper has gone up these last few years. It doesn't weigh much either and that's a consideration for a lazy person.

Exactly, I do this setup all the time... plus I can staple it to the bottom of the joists, no drilling required.

I bet they have a time getting the sheetrock on the ceiling.

Reason I brought this up is because of a TC. Same units, older house shorter run, but #6 was used and the units were tripping the 60 amp breaker. Now I am fixing to wire similar but longer run.

If these units where triping the breaker I would look at something other than the size of the wiring to be the issue. The #6 and #8 copper that I posted al came slightly less than 2% loss.

Over- charge, long line application not used, equipment not matching, etc.

I think stickboy is thinking of unfinished basement or crawl space type areas.

But even when you do have to drill holes it goes in pretty easy. It's light and easy to work with.
