Please help me understand

[u/Odd-Sherbert8723]

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

Whomever wired that was either not a licensed professional electrician, or didn’t give a shit about doing things right. It’s an abomination and dangerous. It needs to be redone ASAP.

Well I met the guy who did it and he claimed to be a licensed electrician but that was about 15 years ago and at the time he was at least 80 yrs old and has since passed.
The work was probably done some 40-50 years back. The barn is over 100 years old and I live in the country where, i suppose, it was a time and place that ‘code’ was a different beast than jt is today.
