How far is to far with underground
We are at the power stage of building. We can either set one pole, then the transformer and meter and then install 580 ft on underground wire to the house panel. Or, set 2 poles, transformer, meter and 430 ft of underground to house 200 amp service panel. After the meter it is the homeowners (MY) resposibility. I have been told we should use 250 size aluminum wire. One electrician said We could go 580 ft. no problem and another said he wouldn't do it due to power loss from the meter to the house. The dilemma is the first pole is free and the second will cost us around $3500 from the utility company. I have an excavator and pipe so digging the underground wouldn't cost me much at all. I found this website http://www.powerstream.com/Wire_Size.htm but don't know what i am looking at. Any other input would be really appreciated.
