Re: How will a BPL system affect the NEC
The articles I have been reading indicate the typical wiring systems in homes would not need to be changed at all. Everything needed to operate a BPL system takes place at the utility and by end-user connection after the outlet.
It appears most systems will operate via a wireless system to an interface box at a local power line or directly through the incomming service with some fancy device that jumps the utility transformer.
I don't understand how it works and I don't have a strong enough background in communications or electronics, but it does appear to be a working system at this time.
