30-amp outlets 3 different connectors?

Is that a GP8000E? Comes with a four prong 30 amp 120/240v service and a few standard home outlets.

That 3 prong adapter will not work. Or generator is something else. Need 240v connector to get 8000 watts out of a generator on 30 amps.

RV 30A is designated for RV use only. the NEMA standard for 120V/30A is a twist lock. So........ RV parks have a 30A RV socket, but most generators and any non RV application has the 30A NEMA twist lock since that is the industry and NEC connection for 30A 120V for everything other than an RV.

Note the "Travel trailer use only" notation on the 30A RV plug.

Now a 30A twist lock to 30A RV adapter is readily available. Try finding a 30A RV to 30A twist lock, I've never seen one.

The big question is why didn't the RV industry standarize on the 30A twist lock?

twist lock is standard industrial, does not come loose with movement
very common on large portable generators

RV/TT 30 amp has flat blades at angles, designed for fixed location

Are you referring to the Marinco style twist-lock socket commonly used at the trailer end of the cord versus the TT-30 plug used at the shorepower end? You should only need an adapter for the TT-30 plug to the generator outlet, and that's not very costly.

Yes that’s the connection.

Just curious why the difference.

Thanks.

Not sure why you need 8000 watts for a 30 amp RV.

We also power some of our smaller mining equipment with it.

Why do many RV’s have a 30-amp 3-prong outlet that is one prong configuration but the 30-amp shore power may have 3 prongs with a different prong configuration?

Getting a portable 8000k Generac to connect to the RV requires yet another type of 30-amp connector.

Spending some $$$ on adapters just curious why no standardization?

are you possibly confusing a 30-amp RV connector



with a 15-20 amp household connector?



both are usually found in a campground/RV Park hookup box. we've been motor homing for 32-years and, other on some portable gennys, have never encountered anything other than the standard 30-amp RV hookup. do you have a photo of the different hookups?

30 amp RV is NEMA 30-TT and they are all the same.



Portable generator probably has a 30 amp twist lock. Could be 3 wire or 4 wire. Not sure why you need 8000 watts for a 30 amp RV.

You can get a generator with a NEMA 30-TT outlet.

Adapters are usually inexpensive. Buy the adapters.
