Attached are a couple of extension cords that I found in my old well house. These were made by the previous owner who was supposed to have been a master electrician on the building of Shasta Dam back in the 40's.

Oh, that looks like one of those Australian style craw foot outlets like the ones I have. Better check the wiring in that dam.

I hope you don't live below the dam.

I live above the dam and to the side of the lake. The more I look around this old place, the more I believe he was just a helper and told people that he was a master electrician.

This is a very informative board and I hope that I will learn alot from the good people here.

Remove the plug on the first "extension" and put it on E-bay.

You'll make a bunch of money, since those old screwplugs are prized by antique lamp, appliance and fan restorers.

Whoa!!,
Is that top connector something you screw into a lamp socket?. [Linked Image]
Where does the Ground come from?.
In the bottom pic, is that paint or corrosion on the outlet part of that extension cord?
Is it legal to have an extension cord without a ground wire/pin on it?.

BTW Tim, Welcome to ECN mate!. [Linked Image]

Thanks for the welcome Trumpy. [Linked Image]
Yes, the top connector screws into a lamp socket. Ground? We don't need no stinking grounds. Seriously, no ground is on it or most of this house.
That is paint on the bottom receptacle. He actually had the ground attached to the receptacle, but cut it off the male end. He also had the hot and neutral reversed.

Probably did that so he could jam the three-pin plug into the existing two-hole socket in the wall.

Home-made cheater plug, anyone? [Linked Image] [Linked Image]

The NEMA 5-15 receptacle has the polarity reversed.

Regarding the "ground" contact on the "junior" crowfoot: It's not electrically continuous with the mounting strap, is it? My old catalogs (GE '36, Wesco '60) do not refer to these as grounding receptacles, but rather as "2-pole, 3-wire receptacles". They were used (rarely) the way we use a NEMA 5-15 today, so the third prong was for equipment grounding, but it wasn't called a grounding receptacle.

The screw plug looks like one of those molded composition ones. The wires aren't removable, are they? My '60 Wesco catalog still lists these!
