Ummm Do you mean how much power can you use untill the power company comes knocking? That really depends. Do you pay you bills on time in full everytime? Does your house reek of marijuana? Is there a 2 thousand watt differance for twelve hours randomly everyday at the same time? Are you pulling Thousand and thousand and thousands of watts when your neighbors are using next to nothing?
Well then you got it made in the shade buddy. Pull as many watts as you can. Just make sure it looks like you a have a reason why your pulling 10k watts, like welders, generators shit like that.
