I bought a 30-Amp-to-50-Amp converter cord from camping world about a year ago, and i used it when we went to mrytle beach with our 2006 salem travel trailer. In my new Emerald bay travel trailer, The circuit breaker keeps popping and i have to reset it.

Can i use this 30-50 amp converter cord to solve this problem, what effects will it have on my trailer.

A few questions:

1. Is your Emerald Bay travel trailer set up internally for 30 amp or 50 amp service?

2. Which breaker is tripping - the main breaker in the trailer's power distribution box or the breaker in the shore power box?

internally it is setup for 30 amp service.

Its the breaker in the trailer not outside. usually it tripps when the air con is on, and the tv and the water heater are all running.

If that's the case, plugging into the 50 amp outlet in the shore power box won't do much to help you. It won't hurt, either, so go ahead and use your 50 amp to 30 amp adapter if you wish.

50 amp service provides true theoretical ampacity of 100 amps (2 hot legs x 50 amps each). Therefore, a 50 amp RV has more than 3 times the power capacity when compared to a 30 amp RV (1 hot leg x 30 amps). If the breaker in the trailer is tripping (assuming the breaker isn't weak), it's because you're trying to draw more than 30 amps. You will probably find that, when you're trying to run the A/C, coffee pot, microwave, hair dryer, etc., you'll need to put the fridge and hot water heater on propane to cut your electrical demand.

awesome that answers my question i just wanted to know if there would be any long term damage. I tried it on my other travel trailer that was 30 amp, and nothing would tripp when i bumped it up with the 50 amp converter. I was just scared using it on my new one.

A 50-to-30 dogbone (I'm assuming that's what you're talking about) lets you plug your 30 amp power cord into the 50 amp socket in the shore power box, but it only ties into one of the 50 amp hot legs. Therefore, the 50 amp shore power breaker shouldn't be the first to trip. Rather, the "weak link" in the system will be the 30 amp main breaker in the RV's power distribution (breaker) box. Even plugged into 50 amp service, any time you try to draw over 30 amps, the 30 amp breaker in the RV should trip.

Are you guys sure the 50 amp plug/socket are 50 amps for each leg, rather than 25 amps for each leg making for a total of 50 amps available?
I'm pretty sure when you use an adaptor 50 to 30 your going to get only 25 amps available from one leg.

Each leg is 50 amps.

Check the 50 amp breakers. You'll find 2 each 50 amp breakers (1 for each leg of the 50 amp service) mechanically linked together. Each leg is 50 amps for a total theoretical ampacity of 100 amps.

Denny, this website reinforces what Ken and Rusty say: RV, 50, 30 and 20A wiring

I am just wanting to know, that if i use the 50 amp adapter plug on my 30 amp service and connect into a 50 amp will it cause any damage, this is actually not a replacement plug it is an adapter that the 30 amp plugs into and then can be plugged into a 50 amp service.

Luke,

No, it will not cause any damage, assuming everything is wired correctly. Your RV's 30 amp system will be protected by the 30 amp main breaker in your RV's power distribution panel.
