Full size ground required?

[rightnitro]

I'm running a generator circuit to my shed with 3 6awg wires, do I need a 6awg ground or can I get away with 10awg, only asking cause I have a ton of green 10awg.

Similarly, what about for a 240v 30a outlet, can I use 10awg for the mains and 12awg for the ground? I already have the 10awg ground like I said, but I'm just curious.

Thanks a lot.

If I have misread the situation, if for example you have an electrical contractor on board to perform the installation work, then send me a PM to explain the circumstances.
