Thanks for the info, "receptacles" got hundred of items, though few
seem to be on plates UK style and none in boxes like a UK 'metal clad'
socket, but I can cut suitable holes in a few project boxes so not
really a problem. There was a splash proof socket in a box but I don't
really want a flip up cover on a permanent installation.
Thank again.

Not too many folks out here refer to them as sockets anymore;
that term is typically reserved for light bulbs, though there is some
variation,
based on age, and geographical location.
Generally, people call them "outlets", but the NEMA terminology is
"receptacle".
Do an e-bay search on: +receptacle 20A 20 Amp (include the +

check-mark "include titles and descriptions" . . . and then sort by
price+shipping lowest first.
That should help you find what you're looking for. . .

If you are cutting your own faceplate(s), then the "new" style
"Decora"
receptacles will be easier to mount - they have a single rectangular hole,
instead of two "double-D" holes.

If the current draw isn't excessive, I might be tempted to purchase
an inexpensive US "power strip" with (usually) 6 positions, circuit
breaker (usually 15A), switch and heavy cord. Decapitate the cord
and attach whatever sort of connector tickles your fancy.

When I traveled to London in 2003, I needed to power four different
electrical devices I was bringing from home, often simultaneously. The
devices all had autoranging or wide-range mains inputs and would run
fine on 220-240V 50Hz, but all had NEMA plugs. I knew there would be
few mains receptacles in my room, and I didn't want to buy a UK outlet
strip and four plug adapters, so I brought a US outlet strip and a
single plug adapter with me.
For anyone that does that, there are two things to be aware of:
1) Check every device you plug into the outlet strip to be certain that
it is rated for 240V.
2) Make sure the outlet strip does NOT contain any surge protection.
I found out later that a friend did something similar on his trip to
Germany, but he took a surge-protected outlet strip. As soon as he
plugged it into the mains, it blew the fuse for the power to an entire
floor of the hotel.

A little OT, but I'm curious. I'm using an IEC strip in one of my
racks--it's the kind with an internal relay hooked to an external
switch. But it's rated for 240v and I'm using it on a 120v line. It
seems to work okay, but I've been wondering if I'm courting disaster.
Anyone have an opinion?

I don't see any reason to be especially concerned. IEC 320 receptacles
and plugs are specifically intended for both 120V and 240V
applications. Obviously you have to be sure that the equipment you plug
into it is rated for the voltage you're using, but you've already done that.

If there are any surge protection components, they'll be things like 275V
VDRs. They'll not clip off small spikes (say 150V ones), but they'll not
be damaged, and won't do any damage to anything else.

Indeed. Most 'surge protection' is simply a VDR rated at a little more
htan mains votlage connected across the mains. Connecting a 110V one
(probably a 130V VDR) to 240V mains is going to blow fuses at least.
I found out later that a friend did something similar on his trip to
Germany, but he took a surge-protected outlet strip. As soon as he
plugged it into the mains, it blew the fuse for the power to an entire
floor of the hotel.
Thati s much less likely to happen in the UK. UK mains plugs contain a
cartridge fuse which is designed to blow before the fuse in the main fuse
box. My experience is that even catastrophic failures (almost dead shorts
across the mains) will blow the plug fuse first.
110V AC supplies are not uncommon in the UK. The reason is that
industrial portable power tools (electric drills, etc) are 110V, and are
run from an isolating transformer with the centre-tap of the (110V)
secondary grounds. The point being that if there's an insulation failure,
the maximum voltage that can appear between some bit of metal and ground
is 55V and a shock from that is unlikely to be fatal.
The transformers are normally in bright yellow plastic boxes (yellow
being the colour associated with 110V on connectors, etc), and are rated
at about 3kVA (there are much larger ones, that's the smallest you'll
easily find). They're not cheap, but an awful lot of hacker-types will
have one.

It's 55V max to ground, well within the limits :-) and it's AC not DC.
An awful lot of tools are 18V/24V/36V DC cordless, of course.

It's not _quite_ the same as US mains. For one thing it's 50Hz, of

IEC 309, or more correctly (and up to date) IEC 60309 or EN 60309.
Often called "Commando" plugs though that's a trademark of a particular

For stuff that doesn't need the high-current connectors (60A or higher),
I'm much happer with NEMA twist-lock connectors (usually the L5-20,
L5-30, L6-20 or L6-30); they're a lot smaller (and lighter) and easier
to connect/disconnect. There's even a 50A 3-phase version in various
voltage (eg http://search.ebay.com/320375960704), though it's nearly
the size of the equivalent 60A IEC-60309 plug.

I actually have a few new marine grade (watertight) 480 VAC

them, put the hardware is just different enough that the set must use
the watertight boxes, and not regular boxes. I could use watertight

Anyway, when I mounded up a US socket for a test cable, I did what you're

Cable mounting ('free') US sockets certainly exist and may be more useful
to you for this application. I have no idea what they're gernally called,
