Hooking up power off my house to my new shed for our buisness, wanting to put it on a different meter for tax purposes. Have 200amp pannel 200amp meter socket and the 3/O wire to run.I have the wire coming up from the ground a few feet over from my existing socket and I was planning on mounting the new meter socket right next to my house socket, piping them together, and piggybacking them together feeding both meters. The oncore guy came by to check it out before I actually knew what my plans were and had said that their line from the pole to the house would hold up to the 20,000 watts I plan on adding to the back, he told me to buy a dual meter socket but Can I just do as planned and piggy back off original 200a house meter to new meter or do I need to take off original single meter and install a new dual socket meter?
