Hubbell is a good source of US standard industrial and residential electrical connectors:

I had no idea so many variations existed. Could you imagine the confusion aliens from space would have in plugging in a shaver or phazer or whatever? Finding the conductors will be easy because

I think Dave is correct and I was mistaken above. Hard to tell without a scale for size, but the proportions do look closer to the 15A version than the 30A version.

According to my reference, here in North America that's a NEMA 6-30 plug, rated up to 250 V and 30 amps. The round pin is of course earth ground. The arrangement I'd mostly likely expect would be to

The official name for your plug is "NEMA 6-15". I once had a 240V through-the-wall air conditioner with that connector. As Kuba said, 240V power in the US is usually center-tapped, so both blades are

There are also Boost/Buck 208/240 transformers for industrial use. I had to install one on a pipe bender for a local company. The machine had always been wimpy, running off 208, but it worked properly

Do note, though, that I’ve seen designs that have an input transformer with a 208V tap, and can be wire-strapped for either 208V or 240V operation. Now that I’ve mentioned it, yours won’t have

That is a “200V” plug, with two phases (lives, hots) on the flat blades, and earth on the pin. In the US, the green conductor color is protective earth, white is neutral, and then black, red, blue

You may, however, find in the cord either a white wire, black wire, and a green wire; or a blue wire a brown wire and a green wire. If the former, white is neutral, black is live, and green is ground.

Oh, and it’s wired as 240 center tapped, so the hot leads are interchangeable and there should be a green earth lead. No neutral in this case, with this 6-15 plug, here in the US power system. Peter

That is a 240 volt 15 amp grounding plug. The mains voltage has been increasing, it was 110-115 for a while (220-230) but now is nominal 120 (240). I don’t know what that supply can handle but those

Sorry, this is a bit off-topic for the HP/Agilent list, but I'm hoping someone, (probably from the USA), can help me. I bought a Gamma high-voltage regulated power supply (0-15 kV, 0-12 mA).

Hi all? I am looking for a?schematics diagram for the HP54522A oscilloscope I have look all the usual sites none there. If anyone has the clip for this oscilloscope I would be interested mostly for

It takes KO4BB a few days? sometimes to clear the upload ques. He will likely get to it this weekend Still the best free manual repository around IMO Dave manuals@...

It's not showing up in the search function in "Manuals". At least not yet ... is there a direct link that you can share? Is it perhaps "Agilent hp Basic for windows Operator Manual-E2060-90001hpbasic"

Part found! Thanks to all for your help. Wayne

Richard, I would be interested in one.? I'm in north west New Jersey. Thanks, Mike N2LYM

Hi, jumping in a bit late here but I had a 9122C arrive today which I was intending to add to my 8757C/8350B setup and I've seen pretty much the same issues you did - but I just fixed them (I think!)

Nope, 3466A, little DVM of the late '70s, very reliable and portable enough to go around in the lab, battery rechargeable option. I also have a 3456A but I use it only for the precision jobs :) > > >

Do you mean a 3456A DVM? I have two of those...very reliable and nostalgia for a first manufacturing job where one was used to do in circuit tests.
