Well, here at my work, running on a 30amp circuit, we have 12 computers, 12 monitors, a mini-fridge, 2 fans 2 laptops and an ari compressor. We have never had a single problem. Now when we were on a 20 amp circuit, we blew the line once or twice and had to reset it.
Don't know if this helps, cause i don't know much abotu electricity. But i hope it does
