Power cable color code

Most electrical sockets I’ve encountered on Apple products are IEC standard, other than the “duckhead” that’s been used in a few places, and that’s (mostly) a standard coupler.

From that “appliance coupler”, standard cables are available for each country.

Cord sets vary.

If you’re not sure which is which, look up the socket and use a test meter.

And if you're not very sure of your skills here, acquire a standard cord set. Or better, check with a licensed electrician, or electrical supply, as they probably have the cord set, or the cord can be ordered from Apple.

Mistakes made in wiring can mean fire, equipment damage, injury, and death, now or in the future.

It's possible that different countries might have different color codes, so you should check with an electrician in your own country to find which cord you should use.
