تذکرات:

Parenthesized colours in italics are used on metallic terminals. "Green/yellow" means green with yellow stripe. See illustrations nearby.

The colours in this table represent the most common and preferred standard colours for wiring; however others may be in use, especially in older installations.

Australian and New Zealand wiring standards allow both European and Australian colour codes. Australian-standard phase colours conflict with IEC 60446 colours, where IEC-60446 supported neutral colour (blue) is an allowed phase colour in the Australia/New Zealand standard. Care must be taken when determining system used in existing wiring.

Canadian and American wiring practices are very similar, with ongoing harmonization efforts.
