Sorry Joe, but this is an approved piece of electrical equipment. The prongs are polarized (one is larger than the other). It probably goes to a unit that has double insulation, which of course does not require a ground connection.

The lack of an actual elecrtrical connection for the ground plug is the clue. the mold used for making this plug can be used for either a grounded or a non-grounded plug.

Of course it could be a bad plug, but I don't think so.

Mxslick,

Maybe it's a silly post. But my point is it seems rather stupid to me that people go around loosing control over this kind of thing while there are, in fact, things more worthy of our attention.

I know it's an electrical forum. But "Russian roulette"?

Rick are you sure the pins are polarized and its just not the fact that they apper to be bent that makes you think they are polarized?

For the record, I've also seen a lot of Chinese extension cords and cordsets sold with polarized AND grounded three-pin plugs. Maybe as a double-protection kind of thing? Keeps the plug polarized even if the ground pin breaks off...

I've never seen non-grounded 2-pin only plugs look like that. All the molded two-pin plugs I've always run across are flat things that look like:

You can be sure that this was an extension cord supplied for use during a seminar and was not what you think or assume it is!

I have many images that are similar.

The lost EGC could mean death to the uninformed, even if they are scholars in the electrical sciences, mslick you said it

Huh?

I apologize for the double post, my computer stopped responding, and it came up as two posts after I restarted it. The Wiremold receptacle was mounted horizontally, it was one of those strip receptacles.


Is there anyone on board who knows how to fly a plane?
