I am coming off a light company pole 150 ft away using underground cable to a 200 amp service panel. Will a 2.0 cable size be adequate? If line drop is too great, I have the option of having the light company install two additional poles with wiring at a cost of $600 and bring me within 50 feet of the service panel. Or I possibly could use a larger size underground wire at greater cost and not have the light company install two additional poles at my cost. Which choice do you think is better and more economical?
