200 amp subpanel
I'm needing a little guidance on a project I'm working on. I've set a meter pole with a 200 amp meter base/disconnect combo. For service into the meter base, the utility company specified 4/4/2 aluminum wire. This pole is for power to my shop building which has a 200 amp subpanel. The distance the wire will need to run is about 10 feet. I'm not sure what wire I need to run from my disconnect over to my subpanel. The 4/4/2 seems really large to try and get into my subpanel.

The wire going from the main meter base disconnect (combo) to the sub panel must be a 4 wire not 3. It must have two hots, one neutral and a ground. The ground and neutral are to be separated at the sub panel. The ground bar to be bonded to the panel and the neutral isolated from the panel.

I really appreciate that information. Just a few more questions. At the base/disconnect combo, do I attach the ground wire of the 4-wire to the grounding lug that has my grounding rod wire? And what gauges do these wires need to be for the 200 amp subpanel with total wire length about 10 to 12 feet?

What is your plan to get the 200 amp feeder from the pole to the building? I would probably use a 2 1/2" PVC conduit from the meter/disconnect to run underground and on into the 200 amp subpanel. I'd pull 2 - 4/0s, 1 - 2/0 and 1 - #4 Equipment Grounding Conductor, all aluminum.
