I built a little man cave outside of the house. The whole thing is being fed by a single 20m wire, not sure what gauge, its just the one I had.
With all the electrical stuff turned on at the same time (computer, projector, ac, fridge, ventilation, lights) the combined power draw should be ~2.5kW. While its all on, I can feel the main cable being somewhat warm-ish, almost body temperature. Is that Ok?
Doesn't have to last forever, I have plans for next summer for some upgrades and am probably going to switch it out then anyways.
