When a plug is wired with black, grey and brown wires what does each colour represent?

Left double quote

If the plug is for a mains-powered appliance, it should be wired in brown, blue and yellow/green but if it is extra low voltage the colours may differ

If the plug is for a mains-powered appliance, it should be wired in brown, blue and yellow/green but if it is extra low voltage the colours may differ.

If you have doubts as to whether your plug is safe to use, check with the manufacturer.
