Getting power to the new shop

My electrician buddy is figuring it for running an a/c. I'm guessing about 3 ton. General Electric said it would still be a 200 amp service, and that it would not require a down guy, I'm not positive why they are saying that with 200 amp that it would only be 3kw. I understand that distance equals less end power, so that I'd probably where it comes from. As overall it's a minimum of 200 feet from the street then two feet more to the transformer.

You mean down guy to a customer owned pole with a panel on your new garage?

I meant down guy on the existing 2-3ft high weather head pipe on your main house IF you upgraded that main panel to 300+ amps because it would need a new thicker service wire to supply 300A plus.

The 3kW they are figuring is not what you might think of as just adding machinery, A/C, lighting, appliance, etc load schedule. That 3kW is what they are using for thier VD/FL calc. There are some different methods/tools the power company uses to get to that "3kW" number.

A/C ton size is the big ticket item effecting VD/FL.

Is the service wire to your existing house directly fed from the transformer pole?
