My home was built in 1996. Can I expect a neutral wire in my boxes? When I wired the WS467s I recall a white wire.
Decades ago... it was common for electricians to run three 16 gauge lines to the over head. One Kitchen ceiling, one bathroom ceiling, and one for the rest of the overhead lights. Then they'd split the "live"
wire at the light junction box and run one 16 gauge 2-wire (no ground) down to the switch. These three overhead runs would often take up nearly half of the 8 circuits in a 60 amp box. This is ancient history and shouldn't have anything to do with a home built in '96.
With that said/stated/posted..... never expect anything in a home to be done correctly (IMHO). I've actually found a recepticial wired with zipcord.
There really is no way to say - it has nothing to do with when it was built (since even the *current* code doesn't require a neutral - as far as I know).......... Your best bet would be to open the box and take a look.
You're correct. There is no actual "national code"... and practices (and codes) do vary... and sometimes are done incorrectly anyway. But... besides being a home owner and Home Automation enthusiast.... I was an old wire-twister, electrical wiring installer (many years ago). I would never recommend anyone... just jump in without a bit of forethought.
OK... sure... home wiring ain't rocket science. If it was too complex I'd never been able to do it. But there are a handful of safety protocols and procedures that are absolutely essential for safety's sake... IMHO. I'd suggest any interested person find a friend/family member/co-worker/neighbor who does know his/her way around home wiring... and ask them to give you a hand. And still... along with a helpful friend... maybe get a loan of a book from the library... and read up on home wiring... as well as doing some YouTube searching and viewing. It's nice to pick-up new skills.
Or even shop around for an electrician... and maybe have a list of desired improvements and or changes (you'd like done) for an estimate.
