wa2wise or anyone else that knows....will that tandem blade hubbell plug in the pic also fit into that NEMA 6-15 receptacle? I can't tell if the pins are wider than the slots on that 6-15 or.....????

Yes it does. I've since used that plug on a European domestic radio set that wants 230VAC. So it can be plugged into a NEMA 6-15 which I have a few of thruout the house.

Here's a female T slot cord cap for extension cords:



Made by Hubbell, 125V 15A, UL seal

Wa2ise: Kinda hard to tell from the pic., are the vertical slots different sizes on that cord cap?

Yes, the vertical slots are differing sizes. Just like a polarized regular 120V outlet.

Were there any T slot male plugs? With prongs with both tandem and parallel parts?

Can't say I've ever seen a male plug with t-shaped prongs....I think there was the standard parallel (NEMA 1-15) and the standard tandem (like what's shown in the first pic)....

I don't suppose there were any plugs in the old days where one prong was tandem and the other parallel? Sorta like what would fit a NEMA 5-20 receptacle or a 6-20?

Also does anyone know when they stopped making receptacles out of porcelain and when they started making them out of plastic?
