Depending on context. In an AC mains power application the earth wire directly ties to a stake that's in the earth outside. This provides a safe return path for faulty circuit conditions.

Ground is a broad term in DC applications where it is the main negative' plane or hookup. However you can have ground in an AC application where it usually is the neutral return.

Generally green in mains power (Australia/NZ and I believe EU) is always the earth.

> In the home electrical stuff I’ve done I’ve mostly heard ground. The earth ground is a specific wire run from the main circuit breaker panel that’s then attached to a grounding rod.

That's the angle I'm coming from. In Australia if it's green and it's in an AC application it's going to earth. It's a standard I believe in the EU as well as a couple of other areas.

Ground in AC can exist but will be floated within the device as a neutral return. It's more the wiring colour standard I was picking.

I know in Australia the term is often used interchangeably, even if it's wrong. Interesting that there's other areas of the world that the language dictates it being identical.

Technically 'earth' not 'ground'. But yea, I pretty much saw the same.
