Also they are adding a 1300 square foot garage for diddling around in and collecting a few cars. It looks like all I have to include in the load calcs is the HVAC and the door openers? No lighting or do I just use the dwelling unit 3VA? Do I include a welder and compressor in the calcs if they are cord and plug connected? How can I know the loads for plug and cord connected equipment if I am only providing a 50 amp and a 30 amp receptacle?
I don't normally do load calcs but I am helping the architect out on this one.
