Let me rephrase my OP. I fully understand AC split phase wiring of the 50 amp supply. I guess I don't understand how combing L1 and L2 in the dogbone adapter supplies 120 volts. Seems like it would produce 240 volts.
I'm asking this because instead of buying a 50 to 30 amp dogbone adapter, I want to take an old 30 amp extension cord and modify the trailer end with a 50 amp female plug, in essence build a 25' adapter.
No 240v through the 30 amp adapter. Pulls power from just one side. One hot to neutral is 120v every day.
You can make a 30/50 adapter any length you want.
