I just got a request from an architect for a design/build project. He calls for a 7.5 ton unit for the second floor.
This is for a residence. Around here you can not get 3 ph. in a residence no matter how rich and fameous you are.
So of course I am going to have to design a 4ton and a 3.5 ton systems for this house.
Is there any where in the country or the world were the power company allows 3phase in a residence?
