I am building a new home 500 ft. from the nearest transformer. The light company set a pedeastal 200 ft. into my property. At the time they did not tell me they were allowed a 3% voltage drop to the pedastal. If I have a max load of 278 amps and run 300 mcm cable I will have another voltage drop of 3%. Now the light company is saying every time a motor kicks on, the lights will dim. They suggest I should have put a transformer on my property and not a pedastal, even though they suggested it. Would I be better off to run double wire in parallel series, or just let the light company install the transformer?
