I have been in the trade for 22 years and worked in several states but this amazed me.
Which way is up? When you mount a 120v duplex receptacle do you put the ground socket to the top or bottom?
I don't recall any code references to this. And I have seen a few installations with the ground socket to the top, but predominantly the ground is down. ('.') ('.') It's seems I remember way back when that I was told this was accepted as good workmanship, that if someone stepped on a cord it would be pulled downward, minimizing the chance that gnd would break first even though it's longer.
Here's the kicker, I did a job, but wasn't there when the inspector showed. Was written up and told receptacles all had to be flipped over(ground on top). Why? I was told it was a local ordinance and was implemented because with the ground on top a cord has more support and less tendency to fall out.
This is news to me and sounds ridiculous.
What do you think? Please include the state your in.
For the record. Sparky66WV and I had this discussion a bit ago. Using my full title (which impresses some.......never the ones you really want ) I sent inquiries to Arrow-Hart, Leviton, and Hubbell. I got NO replies back, so the manufacturers are not going to ring in on this one. Just thought I'd pass this one along.
