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.
