Which reminds me of something I was curious about - I've seen in older
houses (predating grounded wiring) some duplex receps that have two
vertical slots, like a modern NEMA 5-15R without the ground pin, but
also a horizontal slot for *both* the hot and neutral side. Not knowing
the proper name/designation of these I can't find a pic, but hopefully
someone knows what I'm talking about. What was the purpose of the two
horizontal slots?

thanks

I've seen those a lot in old houses, but have no idea what those are
for. Could this be the missing 2-15R on the NEMA charts? Possibly some
240V heating appliances would work on 120V (just not heat as much)?

2-15
It is not missing everywhere

I didn't say 2-15, I said 2-15R. That is missing from the table you
linked to. Only 2-15P is there.

If you have the plug, you get a pretty good idea what the receptacle
looks like.

Do you admit it (2-15R receptacle) is missing from that chart?

If it looks like anything, shouldn't it be in the chart? All the other
plugs have matching receptacles. What happened to this one?

Anyway, would you ever want to plug a 2-15R into the receptacle Nate
was talking about?
