30 amp for RV trailer

We have an RV trailer on a construction site with a 100 amp temporary electrical service. The service is set up with two 20 amp circuits fedding two sets of GFI plugs. The RV calls for 110 V 30 amp and has a power cord with the prongs simlar to a dryer plug. I've been told I can use an adapter and plug into the 20 amp. If I use the A/C along with a couple other items I figure I will trip the circuit. Any damage caused by that. I have the RV power cord hooked into a 12 ga - 25 foot cord

Can I replace the 20 amp circuit breaker with a 30 amp? Is a 10 ga extension cord necessary? Is there a label on the back of the GFI that will indicate whether it can handle 30 amp?

Thanks for the help.

No, you cannot simply replace a 20 amp breaker with a 30.

Yes, you can use the adapter to use the 30a/125v travel trailer plug in a standard receptacle. The breaker tripping is saying it is doing it's job of protecting the wire. If you do go this route you just need to be disciplined with what you run at the same time.

Obviously your best bet is to run the proper 125v/30 amp travel trailer receptacle.


Sometimes I feel like if I answer any more questions it is like someone trying to climb over a fence to jump off a bridge and me giving them a boost.
