Never seen this before is this acceptable? this house has been built on to. The 125 amp main has its own breaker box in the utility room. And the 200 amp main has its own breaker box in the garage.


The 125 is left of the meter and the 200 is to the right.

You really have to look in the enclosures to be sure what is going on but you can legally have up to 6 “grouped” disconnects.


If this really is 350a service the immediate concern would be the size of the service entrance conductors in the mast and the ground electrode conductor.


Which one serves the addition?

I am betting you have a 2ga service drop and 2/0 cu (4/0al) service entrance conductors. If the load calc says that is enough you are OK but if they really added significant loads you could have a problem. I doubt the utility would replace the drop without a lot of coaxing tho.
