I installed 30amp service on my barn for the purpose of running my travel trailer electric system with A/C. It serves as a bunk house for boys and visitors. It works great.This weekend I will have a second RV, Class C with 30 amp connectivity actually, at our place and it will be a hot week. We would like to hook up both the Class C and my TT to the single 30amp receptacle. I assume the purpose of a 30amp Y splitter is to run two RV's out of one outlet 30am receptacle? Anyone use these before?Thanks for your insights and experiences.

My AC will trip a 15 amp breaker. If you have two RVs both running an AC, that will most likely trip the 30 amp breaker. And you sure couldn’t run anything else.

Ill agree, and never seen a 30 amp splitter. Its probably a 12 2 wire. If you need 2 acs maybe run a heavy duty cord to another outlet.

Have not used one. However for best results running two air conditioners set the water and fridge on propane for both RVs. No microwave, hair drier or coffee pot if the air is running.

You can add a Y adapter. But there's no way the two RV's will be able to run the AC at the same time.

I SOLDER all my screw connections in cords. I use quality spec grade receptacles with FORKED 12 gauge x number 6 screw terminals soldered to my conductors. My oh my it's a miracle that troubles have decreased 99 percent :)

Turn off the converter/battery chargers in both trailer as they can draw a lot of juice too.

In my case it's usually the screw connection at the plug itself. Over time those loosen and heat up, or heat up and then loosen. Not sure. I just know better than to push it and run A/c and electric hot water at the same time.

The breaker might be, but that doesn't mean the connections are. I've burned up many 30a plugs on my 5er.

That is typically from poor connections. Especially higher draw outlets that have loosened up from high usage.

I had friends visit a few years back. They stayed in the yard and plugged into a 15 amp outlet approx. 50 feet away. I told them to be careful with their electrical usage because of it. Well, it got hot out enough they needed to use the air conditioner. After they left I noticed my outdoor portch light had stopped working so I took things apart and using that outlet with such heavy current draw melted the connections to the light enough to stop it working.

Even with a 30 amp outlet there will be very high current draw using 2 air conditioners and will likey melt some wires if not cause a fire. I was lucky as my outlet did not cause a fire but it was too close for comfort. Be very careful.

Sounds like an improperly set up circuit. The circuit is protected by the breaker and everything downstream of that breaker should be rated for at least the tripped load.

It was. I fixed it. New switch rewired properly and new GFCI outlet. They had passed the current for the outlet off the hot side of the old switch instead of a pigtail directly to the hot wire. Have since put in a dedicated 30 amp hookup.

I have run 2 15K A/C's off 30 amps. Start one and set is as low as it goes, let it stabilize and start the 2nd. My 15K draws 13 amps running x2 26 amps, I would try and keep all other 110V stuff off. If they want coffee or something run a regular extension cord in from another circuit.

And this is why it's common to see burnt up 30amp plugs.

30amps is a NOMINAL RATING. Some of this is to accommodate short term surges. Under continuous usage it's only rated for 24amps (80%).

Now if voltage is high and nothing else goes wrong, you might get away with 26amps but if the voltage sags (as it often does on busy hot weekends), you will find you are drawing more amps. If you are lucky, it will pop the breaker. If not, it will cook the plug.

They MIGHT work, if they don't start at the same time !
