It goes by AMPS in the breakers .Look at the box if you have a 200 amp box see what breakers can handle the equiptment
.you may have two split up the breakers thats all. i hope this help . maybe do we have a electrical boy or girl in the house...
Some Switches can handle 30 amps so tha might be the way to go .Mine did and i had
over 900 watts going with mine and i had it on 1 30 amp with a GFI breaker NP PROBLEMS
