200 amp breaker downstream from 60 amp

[Jerry Lozier]

We had other issues in other places that will need an electrician anyway but this was a little different to my experience:

Home has 2 meters this one on the barn, (w/ small apartment)

This Main panel has 4/0 Alum SEC coming in with 200 amp breaker(not shown),

60amp breaker (in main panel) protects inside sub panel,

feeders (#2 alum?) attaches to 4/0 attached to a 200amp breaker.

Sub panel had a permit sticker oking 60amp service. (from1990)

(neutrals and grounds were not bonded at sub)

I told client though this is weird I think subpanel is ok as it is still protected by 60 amp in main panel. ???Was that correct?

Is this common?? as I don't know what they were thinking...

BYW... the Bare 4/0 SEC runs underground to a future RV panel(?)

Yeah, assuming nothing else screwed up, no problem. The 200-amp breaker at the sub is now simply a big disconnect.

Presumably, the sub is a 200-amp rated panel. It might be slightly more correct to say the 60-amp breaker is protecting the #2 feeders rather than the panel...but no big deal.

Not common but probably what they had on hand? I'm guessing what feeds what has been moved around.

Hmmm??? How would they connect those feeders (not SECs) in the main panel? I mean, if that main panel is the service equipment with a 200-amp breaker as the service disconnect, you can't just use those bottom lugs to feed something else downstream.

yep, can't quite grasp how they would do that unless they ran something out of meter base which was just to the left of the main panel and those loose 4/0 feeders.
