I'm trying to find the other half of this connector. If you can't read the plate,it says 323-N 3P 4@ 100A 600V.

However, it sure looks like it only accepts 3 conductors plus ground. I don't know what this is and my electrical supplier has been "looking into it" for me for two days but no luck yet.

Any info appreciated.

It looks like a predecessor to arktite by crouse hinds which is a cooper company now.Looks redundant

... and is that a NEMA 1 box outside?

Arktite doesn't seem to have anything quite like it now. And the box is gasketed so I don't think it's a NEMA1...that is if the screw wasn't missing.

Start over wih the correct plug set and correct outdoor box

Isn't that arrow we see someone's trademark ...Arrow-Hart, perhaps?

Is it by any chance a Russellstoll?

I've a strange feeling that outlet isn't domestic... European maybe? Are there any listing agency markings on it?

I have seen a lot of Russell Stoll and they all had round pins.
Are the screws metric? If they are SAE it is probably US.

Not Continental I think, MAYBE British. No other country I know uses "AMP" rather than "A" for Ampere. Besides, 600V would be an odd rating, most stuff used for voltages up to 240/415V is only rated 500V and above the next atandard voltage is 400/690V.

What's the part the arrow is pointing towards? A screw? Or maybe the missing neutral pin?
