Wiring for RV 30A & 20A duplex

[scout4bta]

I'm wiring a 30A RV elect panel, rain proof that also has a 20A duplex. Is it code to use the same gnd wire for both the 30A and the 20A?
Using 10 awg for the 30a and 12 awg for the 20a. Wire it in 1/2 EMT.
thanks,
Steve

Yes. Run a #10 ground and you can share it for the 20amp circuit. You only need a # 12 pigtail for the 20 amp

That box has a bus right? I'm confused when you said you're running two feeds to it. I'd expect a single feed, run to the bus, breakers etc.

Yes is has busbars. The 30a and the 20a are separate. The 20a has provisions for an additional breaker.

No need to run 2 sepeate circuits then.

Run 2- #8’s and a #10 for the grnd. The neutral will need to be white jacketed and ground will need to be green jacketed. Put it on a 50a breaker. If the EMT is complete all the way to the panel, then you dont even need a grnd wire.

Yes every thing is in EMT, metal workshop.
Got it.
Thanks.
