I currently have a CH MBE4040B200BTS Meter main panel on my pump house drawing only power to run booster and well pumps, here is what I wish to do:
Add a CH BRS225 (feed thru) to a CH BR4040B200 Main Breaker sub panel for my shop. Both panels are only 200 amp service, I will not be running more than the compressor ans 1 other item at a time (aside from lighting). Does anyone forsee a problem with my thoughts?? I have a PDF file of my shop elec drawing and the hookup.

Thanks,
Bob

I see no problem with it, looks like a good use of the 200 amp service now just for the pump.

You may want to consider using #4/0 Aluminum instead of the #2/0 copper, one to save a ton of cash, but more importantly reduce voltage drop. If you have a 100 amp load in the shop, the #2/0 will produce a 10 volt drop, which is more than the recommended 3%. If you use #4/0 Al for the same load and distance, the volts dropped will be about 3.5 volts, well below the 3%.

The feeder to the subpanel should be 4 wire, and at least one ground rod will be needed to ground the equipment ground at the subpanel. Keep the neutral and equipment ground separated at the subpanel.

I hope this helps, do not hestitate to get back with any other comments or questions.

I have had them install a Eufer (ground bar attached to the rebar in the slab) in the workshop for grounding it separately.
