But, there is a 100 amp breaker servicing another 100 amp panel?

Are you asking if there is another panel?
Did you take the cover off this panel, is the breaker connected to a circuit?
Is there a downstream panel connected?

Dom.

Top photo is the auxiliary/pony panel connected to the main panel middle photo. You can see the larger conduit connecting the two with the 100 amp breaker see bottom left breaker in last photo. Question is... I have never seen an auxiliary box connected to a main through an additional 100 amp breaker within the main. Hope that is clearer...hope...lol

It really depends upon the loads if okay or not. I would recommend inquiry regarding electrical permit for the added distribution panel. An electrician would need to perform a load calculation on the service and main to determine if okay.

Yes, all good gentlemen. I did get a hold of my good friend an Electrician, who verified all good...Thanks to all for your quick input.
