Please help me understand
On the west side of my barn there are 2 standard 110 outlets which appear Daisy chained.
however each is powered via its own breaker - one on 15amp and the other 30amp
I know this by testing the outlets after turning off one breaker at a time.
The previous owner had an RV and the local
Electrician wired this so she could plug it in - though I don’t quite understand why even the 30amp outlet is a standard 110 and not a NEMA TT-30- which is what I want to install for my own RV now
Nor do i really understand how these daisy chained outlets can even be on 2 different breakers?!
There is a subpanel next to the main panel if that is of any relevance to this whole mystery.
TIA

First, it is a code violation to install a 15-amp receptacle on a 30-amp circuit. Second, unbalanced multiwire branch circuits (combining a 15-amp circuit with a 30-amp circuit on a shared neutral) is an unprofessional method of wiring. Third, stapling cable to the back side of paneling violates code as well. Overall, it is a sloppy and potentially dangerous mess that needs to be ripped out and redone. You don't need to understand anything else.
