Sub-boarding shouldn’t matter. Power doesn’t know how close two breakers are to each other. I would have thought same phase is critical though, if 3-phase.
I had a situation a couple of years ago where my home DHCP started playing up. Turned out my Ethernet over power adaptor had connected itself to my neighbor (separate houses standard with underground power) and I was getting an ip address from his router instead of mine, so I could see his computers and printer, connect to his router from the inside of his network etc. I was tempted to print something on his printer to tell him, but he wasnt the kind of guy to enjoy it. Decided the encrpyption option on those devices is there for a reason.
Anyway, if it does that between separate houses, I dont think a subboard is going to trouble it.
