Wiring up an R.V. Garage for a customer. County wants a load calc. on the prints. I've done load calcs on custome homes but am unsure on garages. I checked the code book, 99 nec, and am assuming to use the farm load calc on 220-40 ?? My calculations will include a 20 amp 120v. circuit for window ac ; 60 amp 220v. for arc welder; a 3/4 hp for garage door opener and some general recepts and florescent lighting.. any help on which calculation method to use... Thanx much!!
