Can my electrical system take the load?

You have plenty to tap at that panel. You should be good with whatever setup you're planning.

Awesome.
That main serves 2 townhouse units.
So is it still ok for me?

As long as their not pulling the same current as you I think you'll be fine.

Thanks man, you've been awesome ! !

Went to the grow store yesterday and forked over the money for an Ideal AC unit. 12,000 BTU, I believe it is. 1350 Amp. Seems like folks are using the split air.
I didn't think I could get away with that where I live. Woulda been a sweet deal tho. I had to get the portable unit that vents out the window.
When I get it set up, I'll post a pic for you. It could take a bit of time since I will have to clean out the space and get the new grow set up unpacked and set up.
Also planning to go out and trip the breakers to see what its uses are.
If you don't hear back from me....send in the drone to check for a crispy fried garden. <;]

This is 100 lb box. Gads!
Anywho, I'll get back to it when I get it unpacked.
The room isn't ready anyway.
