split 50 amp into 2 - 30 amp

Yep, http://www.amazon.com/Conntek-Adatper-Female-Connector-3-Feet/dp/B003YDY89Y/ref=pd_sim_sbs_sg_4, and I am sure if you search around that you can find a better price.

Or for less than 75% of the cost of the Marinco setup you can make your own and have in use water proof covers on each of the 30A outlets which the Marinco adapter does not have. If you don't want the in use waterproof covers the cost drops to around 40% of the Marinco system and all parts should be available at HD and/or Lowes.

Hi,

Or you can create a breakout box that has 30 amp breakers for each leg.

The safety of the idea has not been address yet so let me be the first. You have the potential to overload the neutral of the adapter or the neutral of the recptical or the neutral anywhere up stream of that point. If both 30 amps are loaded to say 24 amps then there is 48 amps on the neutral which will be pushing it and the connections. JMHO.

Got mine on amazon 2 30 amp male to 50 amp female also has led lights to show power and got it less than $70. Worked great.

I may be wrong but I don't think this is right. I believe a 50 amp plug has 2 neutral's and 2 hot's and a ground both hots are 50 amp. If so than you will only pull 30 amps from each 50 amp lead if your plug just splits to 2 30 amp plugs.

An RV 30 amp circuit has a single 30 amp leg or app 3000+ watts capacity. An RV 50 amp circuit has 2 ea 50 amp leg of app 5000+ watts each for a total of 10, 000+ watts.

EDIT The 50 amp RV circuit has 2 hot, 1 neutral and 1 ground pins.

I might be wrong, but I think the neutral will only see the delta amps between the two 50A legs and in your example that should be 0. The only safety issue is if a short happens between the 30A on the dogbone and the 30A CB in the trailer that 30A rated line could be subject to 50A, but is no different than using a single 50A to 30A dogbone which is common practice.

I see no additional safety concerns in what is being recommended except for the fact that those 30A connections are not weatherproof or protected in the linked configurations whereas mine with the in use weatherproof covers solves that safety concern.

Here are pics of my 50A to dual 30A dogbone

With 24 amps on each leg you will have 0 on the neutral. Overloading it is not a concern. The most you could possibly put on the neutral would be 30 amps. This would occur with a 30 amp load on one leg and nothing on the other.



And no, a 50 A circuit does not have 2 neutrals.
