50amp splitter Y cable

[bluecamaro]

Hi there...I have two RVs with 50 amp service - none of which has any 240v appliances meaning I only really need 120v service. I want to share an RV site with single 50 amp (dual phase) shore power, but get a full 50 amps for each RV (obviously not 100). I see Y splitter cables on the market that seem to take 240 v shore power and provide 240v to each leg of the "Y" meaning both legs of the "Y" get L1 and L2 from shore power. This means you have to balance the loads across both campers to not exceed 50 amp on either L1 or L2.
Does nayone know of a "Y" cable that would send L1 of shore power to both L1&L2 of "Y" leg number one (simlar to a 30 amp shore power to 50 amp service adapter), then take L2 of shore power and route to both L1 and L2 of "Y" leg number 2? This would mean each respective camper can manage their 50 amps independently - each receiving 120V and 6kw (50amps). Thanks to all those who respond!

An ordinary 50 amp splitter is going to route 50 amp, 12k watts, 240 volts ( 2-120 volt legs) to each female. Camper 1 and camper 2 will both receive the full benefits of 50 amp service. I'm not aware of any splitter that would do what you want or why there would be, for that matter. The 50 amp breaker at the pedestal is going to let you know if you're pulling too much. Nothing should pull 240v unless you've got a dryer or something. You may not be able to run four rooftop ac's, microwaves, elect. water htrs, refers, simultaneously however. If you have the capability you could lessen the load some by running the water htr. on gas and the refer on gas or battery.

I think he's looking to limit how much he shares on one of the splitter sides.

The dist. panels in each RV will limit what’s shared.

Yes exactly, I know its the same amount of power, I am just trying to allow each camper to independently adjust it's load up to a max of 50 amps. With the current splitters you have to balance the L1 load on camper one with L1 load on camper 2 (sum total for both campers not to exceed 50).....the same for the L2 leg.
In short, it allows each camper to be independent of each other and not having to worry about how the breaker panels in each RV are wired with the only requirement to not exceed 50amps total for each.

the issue with this device is it breaks the nema codes, so you will have to make it yourself.

I don’t see anything wrong with it as long as you keep the neutral in tact. I would build this with independent breakers if I was building one. Make it a portable jobsite type setup.

Yes, I was thinking I may have to build it but was hoping to be able to just buy...(avoid rigging of heavy wire). Did you build one from scratch wire or modify an exisitng adapter setup? Thought about buying the Y adapters I see online and cutting into the "Y" join and re-splicing. But with splicing heavy current wire you always have to worry ( Did I make a good join (?)m- no impedance added from the work). Yes, agree, if I build it having independent breakers REALLY makes the two campers indpendent where if one exceeds 6KW it won't trip a typical dual pole shore power breaker and take the other camper down.

Back when we had our Dutch Star, the MAGNUM inverter panel had a Max Amp limit setting. I never trusted, nor tested it, aside from attempting to limit the incoming 110v shoreline to 5amps for storage.

Worth a look if it applies to you.

I believe this is what you are looking for

The difference between that device and what the OP wants is the separation of L1 and L2.

I did have another thought for OP.

The 50 to 30 splitters are doing just that.

The wire gauge needs to be the 6/8. You would then use the 30to 50 adapter and you get the same result, just no breaker.

The problem is most size it to 10awg

So my question now is why not plug on rig into the 50 amp and one into the 30 amp on the pedestal.

That’s only good if the 50 and 30 are out of phase. Measuring across l1 on 50 and positive of 30 will tell you. If you see 240 then your good to go, but only for 30


In that case I would just split the 50 with a 30 splitter

It hadn't occurred to me that he also might have a 30 amp on his pedestal. It's private so he may not, but if he does that would remedy his conundrum. The 50 amp trailer on the 30 amp plug would be severely limited however to appliance usage and unless there is a pms involved there's no chance of running two rooftop units on 30 amp, ordinarily (unless the rooftop has a soft start capacitor) a 30 amp won't support a running 15k btu unit and microwave simultaneously. I suspect running a 50 amp trailer through a 30 amp dogbone adapter would melt the dogbone and/or the 50 amp male from the RV. Maybe I'm wrong.

 

[bluecamaro]

RedBaron , had exact same thought already......problem is as you state the 10 gauge when the goal would be allow the hot wire in the 30 leg split (prior to the 30-50 adapter) to use the full 50 amps. I could do surgery there I suppose.......and try to add wire in parallel to the hot and neutral of each 30 amp leg. I appreaciate your thoughts....thinking I may just have to buid it all from scratch.

Wemust...thanks for the good thoughts. Problem is in that scenario one line (most likely L1) of sure power will still be shared by both campers. So, imagine if one 50amp rv only runs one AC unit, but the one he prefers to run is serviced by the L1 into his RV's breaker panel. Imageine the second camper does the same - only one AC but he prefers the one connected in his breaker panel to L1 also. Then imagine a few other items are running where each camper is using say 27 - 28 amps each, or say 3.4kw each. Both are actually below 30 amp service usage but because the items they want to run are serviced by the L1 line (L2 line not used much in each camper for what they would like to run), they would actually trip the 50 amp breaker because the L1 line across both campers is over 50 amps or 6.8kw in this example. It is certianly manageable to adjust what is turned on, i just would like a solution where each camper has independent usage of 50 amps, and doesn't have to worrry about what the other camper is using. So both 50 amp rvs would have better service than 30 amp (3.6kw) shore power .....they could use 50 amps (6kw) shore power, just not the full 100 amps (1200kw) supplied by dual phase 50 amp shore power.

 

[Holdmybeer]

So then were it possible to share equally a 50 amp 12 kw supply and provide each share 50 amp 6kw service what can they not use? In much of the country any RV big enough to be 50 amp, has two rooftop a/c's for a reason, which will become uncomfortably obvious with only one in operation come about July or August.
