Can you feed a 200 amp sub panel from a 200 amp panel?

Answer 1

Judging by your question I'm going to take a guess and say you should probably not attempt to do this yourself. Nor do I recommend it.

That being said.

You can either have your service upgraded to 200amp, and install a 100amp double pole breaker and branch it off into a 100 amp sub panel. You could most likely re-use your old panel for the 100 amp sub panel.

Or...

You could have your new 200 amp panel installed in a different location and your current panel wired into it for 100 amps.

Answer 2

Yes this is possible. You are still limited to 200 A overall. You would need a permit and a load calculation to ensure you are not creating a situation where you would be creating excessive load.

Answer 3

You can as long as you don't assume that this gives you another 200 Amps to use. Your overall amperage will still be only 200 Amps. You can supply the sub-panel with a smaller breaker than 200 Amps.

Answer 4

Yes. The interconnecting conductors have to have the same rating as the main distribution conductors. If the sub panel is detached from the main home, the sub panel has to be treated as a new service. This means that the service has to have its own ground rods or plates and the neutral has to be bonded to the enclosure of the sub panel.

Answer 5

Yes, if you have the correct size #2 wire going to it.

Answer 6

No
