Is there a correct way to install 110 volt duplex receptacles. I have seen them with the ground at the top and i have seen them installed with the ground at the bottom

Yes what ever way the customer wants them, up, down, sideways.

Re: receptacles

The ordinary prewired quads tend to be a LOT more expensive than a pair of duplex's. You'd have to be in a real hurry to want to use'em.
 
Re: receptacles

Tony, it depends on the quantity verses the labor.

If you notice, Allen has a pallet full, we have bought hundreds at a time for large projects.

If you do have a job that may have say 300 quads (now don't go putting this many in your Moms house)and the engineer gives you the option of either way, you would be smart to go with the pre made type, especially after quantity price negotiations, (buy outs) and the type shown (Hubbell) does cover the topic of this thread. :)

Wayne, I just showed the HG type for no particular reason, here are a couple more versions.

Re: receptacles

Here in the Chicago area we install them with the ground on the right. But hey we still ruff a house with conduit.
 
Re: receptacles

I was recently reading "Electrical Wiring Residential" by Ray C Mulin. He recommends that the grounding plug be placed in the up position. This will prevent a piece of metal from falling down onto the exposed hot blade of a loosely connected plug. It is a recommendation only, not a code rule. When a receptacle is installed on its side the author recommends that the neutral be in the up position for the same reasoning.
 
Re: receptacles

Scott I think Chicago invented the word RUFF in ruffing in a house LOL :p

In a dwelling there would be very few appliances that have a ground prong on the cord so the installation of the ground up would be of little use.
 
Re: receptacles

All though I think it is a good idea to recognize that cords with right angle plugs can be damaged by having the receptacle in the wrong orientation. I can not find any thing in the NEC that address this. I remember a few refrigerators that had the ground prong away from the cord requiring the receptacle with the ground up but most new refrigerators now have the ground prong toward the cord. which this requires the ground down.

Was it in the NEC before or a UL requirement that on right angle plugs had to have the receptacle oriented as to not damage the plug or cord when in use?

The only thing in the NEC is on trailers:

550.10(C)
If a right-angle cap is used, the configuration shall be oriented so that the grounding member is farthest from the cord.

I think the NEC should address at least right angle plugs.
 
Re: receptacles

Wayne, I believe it did a long time ago. The problem with the rule was the ability to enforce it. How is an inspector going to know that the receptacle is installed correctly? The Code is written for engineers, installers, and inspectors. It is not written for the home owner. The Code has been changing to keep it confined to building wiring. It can not jump out of the walls and protect everything. The instruction that come with the appliance should instruct the home owner or appliance installer to change the orientation of the receptacle if the cord can not handle the stress of hanging over itself. :D
 
Re: receptacles

From Tonyi "The ordinary prewired quads tend to be a LOT more expensive than a pair of duplex's. You'd have to be in a real hurry to want to use'em."
I priced the type shown once, they were about 11.00, that seemed to be less than two duplexs and the labor. One good use is a retrofit for a single gang box, even on a 4S box it saves cutting the drywall out and replacing with a 2 gang mud ring.
