According to National Electrical Code, What is proper installation of grounded duplex receptacle, ground up or

There is no statement in the NEC, it's a matter of personal preference. Although I prefer ground up in commercial buildings because many times I have shorted a receptacle when my measuring tape dropped and crossed the partially exposed exposed prongs in the socket. (I did a lot of measuring and renovating office space.)

Duplex Outlets

I think the ground needs to be up, in case the plug gets partially unplugged and tilted down as they most often do the ground is exposed rather than the "hot ends" of the exposed plug. Also I have had things fall and come into contact with a partially pluged in cord and if it were a thin piece of metal it would short out if the ground was down.

I dont know the code for this, but I always thought that if a plug was not completley in, that is, sticking part way out, and some thin conductor fell between the plug and the outlet, the ground prong would eliminate the possibility of a short. This is so remote a possibility, that I try to spend my time on other safety issues rather than this moot item

There is no code on this. It doesn't matter as far as the code goes which way the ground faces. Some times plugs are installed on their side.

The National Electric Code does not specify this. You can put them in any way you wish. There was no change in the 2008 cycle of the code.

there is no code in the nec for outlets ground up or down.

the inspectors here prefer ground up, but it looks upside down to me. also, some leviton devices say "top" on the yoke of the outlet so the ground is down and manufacturers specs can negate the code.

Why is the retaining screw loose? A metal plate can swing and short out the hot and neutral prongs any way. Tighten the screw so this can not happen.

Haven't seen you lately...have you been hiding out? or just out having fun? Of course, I throw my trash in the proper receptacle at the movies...I don't litter!

i dont think there is a proper way but i go ground down which keeps the plug from wanting to be pulled from the outlet. who cares though honestly. this ? holds less value then "would you like fries with that, sir?"
