need to run electric cable from pole drop to home, about 140 ft. what size cable do I need to use? I am told I can use aluminum vs copper, no city ordinance for copper only. also need to change meter and electrical box, cable will be underground via conduit. Have spoken to several electricians each has told me something different, can you help? Home is approx 1,568 square ft, all electric, three bedroom, two full bath, living room den, kitchen, one boiler, 4 ton ac.
