Yeah, mainly they use gernerators. Ive run a 10k system off 2 sockets and it ran sweet all night. Dont forget to check your fuse rating. Dont forget that modern trip switches are more sensitive to quick surges than long bursts of power. Best advice i can give is split it over as many sockets as possible. Get down to the venue early as you can and test it for an hour on full wack to see if it will trip...Originally Posted by rs1800
