Yep, standardized as IEC-60320-C7
(http://en.wikipedia.org/wiki/IEC_connector#C7_and_C8_connectors), very
very common for all sorts of low-power devices.
Now I find a six foot power cord to be unnecessary. So I have cut
mine down
to a foot and a half. I now need to cut down the European one. I'll try to
get it down to a foot. Here is how I do it:

Don't tell me you soldered stranded wire? That is a major no-no.
Stranded wire must be crimped, never soldered. Soldering causes breaks
of the individual tiny wires where they enter the solder blob when the
wire is moved or bent, thus creating poor conductivity, which in turn
leads to heat buildup and in extreme cases even melting of the solder.

I'm glad you told me that, I guess myself and every other person I
worked with for 38 years in the electrical/electronics field was
screwing up.

Me too... I was taught to solder stranded wire for aircraft systems...
It seems that the aero industry got it wrong. No wonder aircraft are
continually falling out of the sky...

I would rather rely on a solder joint anytime over a crimped joint.

Crimp is used because it is a fast cold system.... no need for an iron.
No need for the same level of skill. No dry joints etc no burnt
insulation, fingers etc etc





Oh Great! I spent $3k on a crimping machine for the rigging on my boat when (silver)soldering the cables would not have created a weaker joint?

Now you tell me! After the 53 foot mast came crashing down in high seas because some idiot ran out of crimps and silver soldered the uppermost cable joints.

Boy... Have I got some news for you and it is all bad!

Forget the stainless rigging cable and focus for a moment on 240 volt, 3 core power leads. Are you seriously trying to say that a soldered joint does not produce a weak point at either end of the join in a flexible power lead? If you are I think you need a crash course in reality mate.

The only reason an Electrician has for soldering a joint is to ensure electrical conductivity. Nothing at all to do with strength and everything to do with single mindedness whilst neglecting the likelihood of broken joints and discarding the purpose for using multi stranded wire in the first place... Flexibility. That's why it is forbidden to use multi stranded wire in walls of houses... It can break! If you solder it, it is almost guaranteed to break in a situation of movement of the cable!

You're comparing apples to oranges, what does a cable for a mast have to do with electrical connections? As far as solid wire being stronger then stranded I'll argue that point also, solid wire in a house doesn't get moved. We had a couple of antique overhead cranes where I worked that were wired with solid wire and 99% of the time when one of them went down it was because the wire broke from vibration where it went into a connector. We also had to use crimp connectors on the pendant cables which were made up of stranded wire and we also had problems with breakage where the wire went into a crimp connector.
