Hello I'm working as a helper in electrical firm. We did electricity in the five buildings. However the electrical power to the building does Con Edison. Does Con Edison well provide AC and DC or just AC? Thanks in advance
I don't know about Con Edison Power Co. I live in Pennsylvania. The Power Company in Pittsburgh, (Duquesne Light Company) provides a code / specification book. It doesn't list DC power, only AC power available to customer. I would think most power companies operate the same.
