Makes perfect sense considering there is a likelihood the spring-loaded metal cover will rub up against the plug pins if someone were to pull the plug out without moving the cover out of the way first.

By the way, does the outlet really look like that? With the two t-slots?

I didn't know they still made those. You can stick a NEMA 1-15, 2-20, 5-15, 5-20, 6-15 or 6-20 in there. [Linked Image]

Sven,

I don't think the cover could ever contact the pins on the plug. I think the sticker is more likely an FYI on which way the Receptacle is installed so people would not have to bend down and look under the cover.

Yes, I agree, and that makes sense too! The cord cap is inserted and then twisted to make contact.

Ah shucks! I thought I had a winner!!

Joe, if you are implying 110.3(b), may I ask if this is listing or manufacturer's instructions?

Also, does the NEC address manufacturer's instructions like every other code in the world does, or just listing?

Ryan:

I believe that the answers to your questions would be Yes.

Here's a sample of the information and "instructions" I found when I searched for this type of equipment.

Quote
The plug must be fully inserted in the receptacle and rotated clockwise to manually operate the enclosed switch, closing the circuit to the receptacle.

Joe I apologize if I am hijacking the topic here, but if what you say is true, consider the following:

There are several manufacturers of panelboards who include in their instructions to only install their brand of breakers in their panels. There are also some breakers that are listed to be used in their panels. Now I ask: Does a listed breaker installed in a panelboard, against the instructions of the manufacturer, comply with the code? Please include a reference for my learning. Thanks

Ryan

The information that is printed on many panelboards is a complete set of instructions, and specifications, and includes a specific warning that makes it clear that the use of other devices, not manufactured by "the companies name" will void any warranty, etc., etc.....

Joe, I'm certainly not saying that its a neat thing to do, but is it an enforcable violation?

IMO,if the breaker(s) of another manufacturer are UL listed for use in different brand panel(s), I don't see a violation of the NEC. The only issue would be the warranty from the manufacturer of the panel. I think that in most cases where a different brand breaker is added in existing panel, the warranty has long expired anyway.
