I have a friend who has acreage out in the country in the planning stages for a new home or barn-dominium. The transformer and POCO pole are in the NE corner of the property and currently supplies a little storage shed. He is planning on building in the middle of the lot some 800-900 feet from the power supply.
If we trench, we are looking at approximately 1250 feet of trenching, 3 parallel runs of 250mcm CU or 400/500mcm AL with 200A total load, household voltage.
We could go overhead and shave off 300 feet, give-or-take, and use open-air conductors which allows greater ampacity but doesn't change voltage drop. I have no experience running overhead lines on poles. The guy says he has a gentleman neighbor that has a stinger for setting poles. If we went that route, how far apart between poles, recommended pole height for the distance, and sag?
We've discussed setting xfrmrs to step up then back down but the costs seem to equal out.
Is there another method I'm not seeing.
I'd appreciate any thoughts or ideas.
WOW! Sounds like a no brainier to me.
You need to convince your friend to give the POCO the easement rights to service "their", line, pole/s and transformer.
You might want to see what the cost would be for an underground feed and a pad mount transformer. Then your friend doesn't have to worry about removal of any trees for an overhead power line. Not only that, it will look a whole lot better.
