If PA uses UCC code, do I need an air gap?
I just read a bunch of posts basically saying "few states other than CA require an air gap anymore." I also skimmed one that I think said that IRC codes don't require an air gap, but UCC codes do. Except that I closed that tab and can't find it again!
I live in PA, which uses UCC code, but I can't download the actual code itself to look it up. Does anyone know if PA requires an air gap, or if UCC code does?
