Plugging 30A 5th wheel into 50A service
Will I have any problems if I plug my 30A fiver into 50A service at a RV park. I will not be drawing any more than 30A, but the park says I should pay $50 deposit to rent a "box" from them.

However. Put one meter lead in the 3 o'clock hole and the other in 9 o'clock and you will read 240V, there are two hot legs and are opposite phases.

Actually they ARE the same phase, just opposite ends of a transformer that has a center tap neutral. AC power in the US is delivered in three phases that are 120 degrees offset from each other. That is because the generators are built with three windings.
