"I have a 200 amp panel in my house with 7 avalible slots. I want to run from it to a 100 amp sub panel 275 ft away. What size wire and what size breakers should I run to the sub panel? Then from the panel I was going to run in the barn 3 shop lights and 4 plugs. Then go about 75 ft to a pavilion to run 3 lights and 6 plugs. What and how should I do this. The advice I have gotten at the home stores very as much as summer and winter. Help please

Are you going to bury the cable or run it overhead? A total of 300 ft+. Is a pretty expensive proposition. Will the local power company run another pole and wire to a separate meter? 2/0 is

I was going to run underground I talked to the power company. He said I would have to buy the pole and get a electrician to set the box and run everything. Then have it inspected. Then they would come out for 250.00 and run the line. 125.00 to set the meter. 17.00 a month plus kilowatt usage.
