The end of the power cord is snipped off this 11/34a I have in front of
me...
It has a blue wire, a brown wire and a green striped wire.
I'm assuming the green striped is ground. Brown hot and blue neutral?
(I think this is a standard, but I shy away from voltages above 48vdc :-)

Yeah, that's right. Not sure about the 11/34, but especially on things
designed to be dual voltage, you can swap the blue/brown wires 'round
and it'll work ok. Just gotta be careful if the neutral wire is used a
s ground lead...

Argh, no no no no no! Blue is always Neutral, Brown is always Phase!
Horrible things can happen in switched mode PSUs if you don't follow
this, although for lamps and stuff it doesn't make much of a difference.
If you're not in the UK then you might want to check that you have the
appropriate voltage selected.

Care to expalin why? Every SMPSU I've worked on has had a totally
symmetrical input (with the possible exception of the mains filter
capacitors) and couldn't care less which wire is 'hot'.
IIRC, the regulations explicitly forbid making assumptions about one of
the wires being close to earth potential, with the exception that you can
have single pole switching (and of course the single-pole fuse) in the
live wire only.

Exactly.

It's certainly a standard used in England and the rest of Europe. All our
flexible mains cables (not the rigid ones used for house wiring inside
walls [1]) use this colour code.
[1] House wiring colours, at least for single phase, are : red = live,
black = neutral, bare (but sleved with green or green/yellow sleeving at
the termination points) = earth)

err, except those places don't exist , do they ?
We get this all the time from the Anglosaxons, only England exists - until
something goes wrong - then the Brits get the blame. Geoff.

Erm, it's standard in Scotland, Wales and Ireland too... Gordon.
