Where can I get tinned copper cable in the UK the same as used for fan cables (1.2mm) and for molex cables (2mm) in the obligatory red, blue, black, and yellow colors? Will this cable be suitable for fan cables? http://www.maplin.co.uk/products/module.asp?CartID=040804145824905&moduleno=6192&Products=17 Maplin don't appear to do the same cable in a 2mm thickness. I notice that my PSU's manual states 18AWG and 22AWG wire is used. This is the thickness correct? And lastly, what maximum current rating should I looking for in cabling and how is it important? What kind of specs should I be looking for in a switch if I want to replace my cathode light's rocker switch? Same goes for a push-to-make switch which I would like to turn on/off a series of LEDs from a 12V supply?
