50A vs 30A RV Outlets on Generators

What 30A and 50A mean on a generator listing

The words "30 amp RV outlet" and "50 amp RV outlet" in a generator listing name one connection on the unit. They describe the plug the generator offers for an RV, and the amperage is part of that outlet's stated rating. The two outlets are different connections; a listing that names one of them tells you which plug form the unit carries.

The outlet words are separate from the generator's overall output. The first watts figure in a title describes the generator as a whole, while the RV outlet name describes a single receptacle. Read both, and read the maker's page for the full list of outlets on the unit. The outlet types guide explains how these connection words appear across listings.

Which RVs use a 30A inlet and which use a 50A inlet

In general listed categories, smaller rigs such as pop-up campers, small travel trailers and many mid-size travel trailers are built with a 30 amp inlet. Larger motorhomes and some fifth-wheels with more onboard systems commonly carry a 50 amp inlet. These are common pairings of rig type and inlet rating, and your rig's own documentation states which inlet it has.

The generator listing's outlet words should match the inlet your RV maker installed. Check the plug on the RV power cord and the spec sheet from the RV manufacturer before you compare generator listings. The RV maker, not the generator listing, is the source for your rig's inlet rating.

• 30A outlets on listings: paired in common use with small travel trailers, pop-ups and mid-size campers; verify the rig's inlet.
• 50A outlets on listings: paired in common use with large motorhomes and some fifth-wheels; verify the rig's inlet.
• Your RV's inlet rating is listed by the RV maker; use it as the reference when reading generator listings.

Reading the outlet words next to other features

A listing may name the RV outlet in the title, in a bullet list or in a feature line such as "RV ready" or "30A RV outlet". The place it appears does not change what the words mean; the outlet name always points to one connection on the unit. A "50A RV outlet" in a title and a "50A RV outlet" in a bullet describe the same connection.

Compare the outlet words to the rest of the listing. A generator showing a 50 amp RV outlet may carry a watts figure in a completely different range from another unit with the same outlet word, so the outlet name alone does not tell you about total output. Look at the RV generator guide and the 3000 to 5000 watt guide to compare generators by stated details, then confirm the outlet on the maker's page.

What the outlet name does not tell you

A 30 amp or 50 amp outlet name states a connection rating, not a promise about what the generator can run. This site's catalogue carries no measured output, runtime or fuel use data, and no article here sizes an RV's loads. Sizing your rig is a question for the RV manufacturer and, where wiring is involved, a licensed electrician.

If a listing says "RV ready", that is a seller's feature word, and the same rule applies: read the outlet names that follow it and confirm them on the maker's page. The portable generator guide compares units on their stated details, with the same limits.

Questions for the RV maker and the generator maker

Ask the RV maker which inlet rating your rig has and which power cord it takes. Ask the generator maker which outlets the unit provides and whether an outlet matches that inlet. The maker pages in the sources section publish product information for their own equipment, including outlet details.

Then compare generators the way this site does: on the stated details in each listing, with the watt groups, fuel type and feature words read side by side. The camping generator guide and the dual fuel guide show how those words group units for different trips.

Use and the maker's manual

Run the generator outdoors according to the maker's manual, and read the carbon monoxide guidance on the CPSC, CDC and EPA pages listed below in sources.

Keep the RV power cord and the generator outlet matched, store the unit as the manual describes, and treat the outlet words as part of the listing's stated details.

What to pick for your situation

Questions

Does a 50A RV outlet mean the generator has higher total output than one with a 30A outlet?

The outlet name states the rating of one connection, and the generator's total output is a separate stated figure in the listing. Read the watts figure in the title and the full outlet list on the maker's page; this site compares stated details only and gives no output promise.

Which RVs have a 30A inlet and which have a 50A inlet?

Smaller trailers, pop-up campers and many mid-size travel trailers are commonly paired with a 30A inlet, while large motorhomes and some fifth-wheels are commonly paired with a 50A inlet. Your rig's inlet rating is stated by the RV maker, so check the RV's documentation and its power cord plug.

Can I plug my RV into an outlet with a different amperage than my inlet?

Match the generator outlet to the RV inlet. The 30A and 50A outlets are different connections, and the listing names which one the generator provides. If you are unsure which connection your rig takes, ask the RV maker.

What does "RV ready" mean on a generator listing?

It is a seller's feature word that points to the RV outlet on the unit. Read the outlet name that follows it, and confirm the actual outlets on the maker's page.

Why doesn't this site tell me which outlet to choose for my rig?

The catalogue here contains only the stated details from each listing, with no measured output or runtime data. The RV maker states your rig's inlet, and the generator maker states the unit's outlets, so those two sources decide the match.
