50 amp vs 30 amp

Hello,

I heard that some camp sights have 30 and or 50 amp plugs and that they use the same exact prong arrangement.

It this accurate? I don't know much about how this works, but I'm sure if you use the wrong amperage it will
burn up the electronics in a camper.

Do the Jayco featherliites uses different amps?

Do I need to keep some kind of converter handy?

Thanks,
Jay

Standard 30amp/50amp female/male connectors are not the same.

No reason it would damage anything. The voltage remains the same only the available current changes. If you use the adapter plug to plug your trailer into your house you are now on a 15 amp service. Works the same but if you draw more then 15 amps you'll pop a breaker.

I believe the 50 amp service is used on large trailers with two AC units. It's the only thing you might have that would draw that much power.

Thank you - I started looking at converters and the plug configuration seemed different

I appreciate the help.

All 50 amp plugs have 4 prongs - 1 for ground, 1 for neutral, and 2 for the two 110V circuits. All 30 amp plugs have 3 prongs in a triangular arrangement - 1 ground, 1 neutral, and 1 110V circuit. Voltage is the same, but with 50 amps, you can run more things at the same time. For example, my trailer is wired for 50 amps, but only one A/C. But I can run the microwave and a small space heater and the A/C - all at the same time. Hope this helps.

30 amp plugs do NOT all have the same triangular arrangement. Only the 30 amp RV plug does.

My trailer has a 50 amp connection and have an adapter cord to hook up to a 30 amp connection.

AC and Space heater at the same time? Where are you camping :-)

I obviously do not run the A/C and heater at same time. But have tried it for a short period of time, just to see if any breakers would pop, and none did. The statement was just to make a point. Sorry if I confused you.

To be clear RV 30 amp power is single phase 120VAC circuit, 50 amp is two separate opposite phase 50 amp 120VAC circuits. If you wire across the two phases you get 240VAC however this arrangement is uncommon in RVs. Usually, the circuits are used separately to power 120VAC loads. If you use a 50 to 30 amp adapter you are using one leg of a 50 amp circuit. Interestingly enough this is why you cannot combine two 15 amp circuits to get to a 30 amp single RV circuit but you can use a 30 amp plus 20 amp adapter cord to power more of a 50 amp RV (obviously you can't draw the same as you could with 2 50 amp circuits) setup. The reason for this is in 50 amp RVs the AC panel is split into two poles one fore each phase. 30 amp RVs only have one pole.
