Main breaker requirements

[Jeffryp]

I have a 400 amp meter on a commercial building with 2 200 amp disconnects one feeds the building the other one feed an exteriour panel on the side of a metal building on the same property. Am i required to put a main breaker in there panel on the metal building as well as the exsisting 200 amp disconnect?

seems like 225.32 would be more appropriate.

That is slightly confusing it doesnt quite say i need a main breaker on seperate build my county inspector is insisting both a disconnect next to meter and a main breaker in the panel its feeding in a seperate building on same property ive never had to do that in my career

Each separate structure requires a disconnecting means it can be a main CB in the remote panel.

Seems to me it is just like a meter main so I would think the outdoor disconnect is all you need

The disco at the meter is debatable; the disco at the separate building is required.

The disco at the meter is debatable; the disco at the separate building is required.

Would the two service disconnects need to be grouped at the meter location?

You are required to have a Disconnect or Main breaker on or in the separate structure.

I don't see how no disco for the separate building feed would be acceptable for a commercial application.
