    I have an IEC cp22s that only accepts 3*1 mm2 conductors. I want to solder a cable with 3*1,5 mm2 conductors. Is there any problema of mecanical stress due the larger diameter of the conductors?I´m doing a power cord or a mains lead!

    You can see the IEC at the end of the site!

    Miserable PDF on that page. Can't read the sizes.
    1MM dia is less than 18 gauge American. I certainly hope you can fit a larger wire on those terminals!

    Why do you think so?I have read that these terminals only accept 3*1,0 mm2, but was on an Internet site, so I´m not sure!

    mm squared? Maybe I interpreted that wrong.
    math math math...

    I'm getting cr@p out of my calculator.
    Maybe it's the drugs...:D
    (Recently out of hospital. Promised not to do math on the website this week.)

    Somebody, help me out here!
    I've lost my math brains for a while.

    "CLIFF CP22S 3 pole appliance plug. Rewirable. Rated 10A 250VAC.
    Cable connections can be made by soldering or by screws.
    Max cable 3 x 1.0mm2. Fits MS-1 and MS-3 inlets."

    From that description, I'm not sure if the size limit is due to the cable entry or the screw terminals. If you are able to terminate the cable ends and still close the connector housing, I think you should be fine.

    Why would they require 1 mm wire which can pass 2,3A max. and rate the switch for 10A?

    That's what I was barking at, but I can't prove it with math right now.

    1.5 times the area of the cross section should flow 1.5 times 2.3 amps. Right?

    1 mm wire can pass 2,3 A Max,? How did you do the calculus?

    More likely it was a look-up table. The current limit for wire is often about the quality of the insulation. Some wire is rated for 60C, some for 75C and some for 125C. Your casual power cord and hook-up wires are usually rated for fairly low temperatures.

    OK it seems that we didn't read the datasheet properly ;).
    Basically it says that it includes 3 x 1mm wires that are sticking out so you can solder them :D.

    And soldering the IEC doesn´t have the problema to break with time?It is a rigid connection...

    it is to solder the wire to the iec connector
