Can somebody tell me how to connect a 3 pin plug( UK) to a cable from USA?
I need to know which is live and which is neutral.
Thank you

In the US cable, the white is neutral, black is hot, and bare or green, ground. I don't know the UK plug. Not sure any UK chaps hang out in this forum. Likely the ones in the computer or plumbing could give such basic information. Sometimes, say a SP3 cord, the wires aren't colored. If one is tinned, it is the neutral.

Assuming you are dealing with the UK voltage and connections, I do not want to assume you are aware that the nominal voltage of Britain is 230 volts, so two of the wires ( the word "core" is used in place of wire or conductor in UK) are hot at 230 volts, and the third is the "earth ground".

As it illustrates the various color codes used in the various countries.

Thank you very much.
You were very helpful, and I appreciate it.
