I am looking for some vintage AC power cords for older HP test equipment.
I have a number of pieces of test equipment, and only one power cord. The
only marking on it is "Electricord". It is a three conductor cord that
uses three round female sockets on the end that terminates at the
equipment, and is similar to the old power cords that were found on coffee
pots and such (but with one more pin in the center offset from the other
two - a ground, I suppose). I believe it is typical of HP equipment made
in the 1960's to have these, such as the HP745A AC calibrator, among
others. Does anyone know where I might find some of these, or perhaps know
what the original HP part # is? (I know that I could hard-wire a standard
line cord to these units, but would much rather have the proper cords.)

Thanks!

If they are the same ones used on old electromechanical Victor and Burroughs
adding machines, I have those in stock. Send e-mail to
.

Be aware that there are two different pinouts on these cables.

Good morning.
On these, when looking at the hole end with the center hole towards the top,
left hole is hot (black wire), center hole is grounding (green wire), and
the right hole is grounded or neutral (white wire).

Thanks,

Hello Lee,

Jeez, I don't know. Do they look like this?:

Also, is the center conductor ground, or can it be re-wired if not? (Not
molded)

How many do you have and how much are you asking for them?

Thanks!

Hello Michael,

Thanks for the info. Perhaps they can be rewired, or if it comes to that,
I suppose the male ends can be cut off and rewired.

I should probably also mention that the width and length at the end of the
thing is 15/16" x 1/2".

Thanks again.

Good morning.
That looks like it, except these are gray. In your picture, the hole on the
left would be grounded or neutral (white wire), the lower hole in the center
would be grounding (green wire) and the hole on the right would be hot
(black wire).

These are factory molded on both ends, you cannot get to the wires without
cutting.

Thanks,
Lee Richardson

Good morning.
That is what these measure. If by chance they would not fit, or are wired
wrong for your application, I would gladly take them back, including the
original shipping or postage. The office machines using these cords were
made in the late '50s or early '60s, and used on up until the early to mid
'70s when the 3 slot IEC type became more popular.

Thanks,
Lee

They sound good! How many do you have for sale, and what would the cost
be?

The last time I looked for these they were available in office supply

What? I agree that power cords don't infulence sound, but nobody said
anything about sound or even performance. He has equipment with non IEC
connectors on it and doesn't want to have to solder a power cable on it.
Read the OP.

There was a discussion here (sci.electronics.equipment) several years ago
that included the Belden part numbers.

Looks like I saved it. Here's the highpoints (minus the flamewar).

These are still being made. They are listed in the current Newark
Electronics and Allied Electronics catalogs. If you look for a
Belden 17280 cord you will find them. They are about USD $5.00 new!
BTW, They may actually be under the Volex name, since Belden sold
the manufacturing to them a bit back.

I seem to recall going thru this 15-20 years ago. At that time I
checked the Belden catalog and discovered that there were TWO
DIFFERENT types of these. They differed in the way that the oval end
was wired.

The standard way has the ground on the center pin, but the old HP (and
Harrison Labs) equipment used a non-standard configuration that put
the ground on one side.

This left me with a quandry. Should I buy standard ones and rewire the
HP gear to be standard with the thought that it was less likely that
someone might come up with the correct, but uncommon, cord and make
the chassis live. Or should I buy the right cord and take a chance
that that cord might migrate to a more conventional piece of
equipement and make IT live?

In the end, I bought the conventional versions and rewired the 3
pieces of HP gear that we had.

That was easy, but in retrospect installing the newer style of power
entry module would have been better, as there would have been no
possible confusion thereafter.

So, does Belden still make both styles, or is someone here just
assuming that since the oval connector looks right it must BE right?

Jim, Belden/Volex still makes both versions. The 17280 is the
standard version and the 17952 is the one with the swapped line
and neutral. Oh yes, the 17280 is 7.5 feet long, and the 17952
is 8 feet long. I wonder if the length is different to allow you
to tell which cord you have without having to test it.

Thanks. At least it was the ground and neutral that were switched, but
even that could be lethal if swapped. A really bad situation.

Jim, it isn't the ground and neutral which were swapped, but line
(a.k.a., hot) and neutral. (I think this is what you meant. :-)

(You probably already know this Jim, but for those that don't...)

While this may not look like a real big problem because the line
and neutral simply go through a fuse and switch to the transformer,
there is a subtle issue which is potentially lethal.

In this case, the line and neutral are completely isolated from
the grounded case. Where the problem arises is the switch and
fuse are now in the neutral rather than hot line. This means
even after pulling the fuse, much more of the circuitry remains
"live." This is only slightly better if the power switch is used
to break both the hot and neutral.

From the Volex site (http://www.volexpowercords.com/) for the
17280 cord: 'Polarity as mandated by CSA electical (SIC) Bulletin
895B and UL817.' And for the 17952 cord: 'This cord is made with
non-standard polarization and has a cautin (SIC) label applied
to the cord stating this fact: "This cord is for replacement
only and is NOT intended for new original equipment."'

This probably isn't up to code, but for my function generator I cut the
end off another cord and crimped yellow (12ga?) but splices to it.
Slightly crimping the other end made a socket that nicely fits the pins.

Looks ugly, but works.

I've done something similar but filled in the space with hot glue to mold a
connector. If you wax or otherwise lubricate the socket, the hot glue won't
stick to it and you can use the socket itself to mold the shape of the plug.

A better option may be to retrofit the equipment with standard IEC power
sockets which can be salvaged from junk computer equipment.

Well, all it takes is an archive of the newsgroup* since it got
created and a vague memory of something. And then you "grep for it".
It takes a while though, (Google can be faster).
