50 to 30

Hey y’all
Camping with shore power. Could you solve some of problems of tripping breakers if you used your 50 to 30 dog bone on the 50amp breaker side?

To be clear, what breakers are tripping? The ones inside the trailer, or the ones on the pole?

If it is the ones on the pole, can I paraphrase correctly that you have your trailer connected to the 30A outlet and the breaker is tripping, and you are wondering if you attached your 30A plug to a 50A adapter and plugged it into the 50A side would you have a different result?

My understanding is that a 50A outlet actually contains two 30A circuits, so a typical adapter would just tap into one of those 30A circuits and you would have the exact same results.

good luck!

Thanks Belegedhel
The breakers on the pedestal are flipping,cords are clean and not more than 20’. Just thought maybe the 50amp side gets used less and the breakers may not be as spongy.

50 to 30

A 50 amp outlet has two 50 amp breakers tied together. The 50 to 30 dog bone just sends one of those to the 30 amp trailer plug. The pedestal breaker will hold even if the internal trailer 30 amp breaker trips. That’s why this should be more reliable power.

A 50 amp circuit is effectively two 50 amp 120 volt hot supplies, a common neutral and a safety earth (green ground). As long as you use the right dogbone, all will be fine.

The short answer is, yes.
Only because you will be plugging into a 50 amp breaker rather than a 30 amp breaker.
That doesn't allow you to run everything at once or you might trip the breaker on your converter, or worse, melt your plug.
It's possible the 30 amp breaker in the power post is old and weak. I think I'd call the office and ask for a new breaker.
(I agree with rmkrum)
