When you have a dog bone style adapter, 30 at the pedestal to the 50 amp motor home plug, are both hot legs on the 50 amp side wired with the one hot from the 30 amp plug?
Yes, that is exactly how they are supposed to work
Another related question; I have a voltage regulator rated for 50 amps. using a 30 amp plug at the pedestal to the regulator "in" side which has a ground, neutral and hot leg position.
I am not sure you are using the word "Regulator" properly but. If the device is designed for a 50 amp RV then the plug should be 4 wire 50 amp same as the RV's shore cord.. you use the dogbone adapter on that plug.. And plug the RV into the "Regulator"s outlet.
The Green (ground wire) is common to everything.
If the "Regulator" has only one hot (Black) one neutral (White) and ground (Green) it is not a 50 amp RV product.
Also what is it.. I'm guessing it's sometime else. But I hate assuming.
