I'm looking for a wire sizing chart that also has the minimum size conductor for the ground. I've searched my electical contractors book and it has all the wire sizing charts for voltage drop, etc but they don't include the ground size.
For example, a 200 amp service needs a 4AWG ground wire. I think 100 Amp is 8AWG. I'd like a chart that goes from 350 Amp service down to whatever size it is where the ground and hot/neutral are the same (I think its maybe 20 or 30 Amp).
If anyone has an online reference, please post the link for me.
Thanks!
