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.
Whoa!!, Is that top connector something you screw into a lamp socket?. 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?.
Thanks for the welcome Trumpy. 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. Tim
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!
