I am designing my own house and site plan, and intend to possibly be my own general contractor for my build. I own 63 acres of land that I have been working on for 10 years now, logging 10 acres, digging two ponds, and a bunch of other stuff. It is now time for me to finalize the site plan, and contact the utility companies.
The site plan so far has the house and a barn/shop about 700ft from the road, with possible future pole barn structures even further back.
I have contacted the power company, and so far the site planner has provided me with the specifications for installing a single phase padmounted transformer: https://www9.nationalgridus.com/niag..._esb754a-1.pdf
I fully understand what is required of me in terms of the high voltage trench and the transformer pad excavation. What I need better definition on is the low voltage cable from the transformer to the structures, in particular what kind of cable, and the max length.
I know that this particular power company requires home owners to sign waivers if their service line from a pole mounted transformer is longer than 300ft, the waiver is to absolve the power company from any customer claims of "degraded" service etc.
Here is an image of two possible transformer locations on my site plan: http://i.imgur.com/QRWbAcP.jpg
Option 1 would cost me about $6400 for installation of the transformer and meter. Option 2 would cost me about $9300.
My question is basically, do I NEED to keep the structures within a certain distance from the transformer? I have been told the "closer the better", and "try" not to exceed 300ft.
Is the extra cost of more high voltage cable worth keeping the structures closer to the transformer? Not being an electrical engineer, I don't know exactly what the consequences are if I'm "too far" away from the transformer for "good power".
I will have a fair amount of equipment in these structures, welders, plasma cutters, overhead cranes, basic farm equipment etc.
I should add that, the power company has ruled out the use of the west power pole, as it has a capacitor bank on it. So my only option is the east power pole.
