Excellent diagram, Dave. Did you create that yourself?

Thanks, Yes I drew it. It's just a simple MS Paint drawing. Does not show everything (breakers, connection of 30/50 Dogleg to a 30 amp connector, etc.) as my only intent was to show voltage at the plugs and how it is derived from the transformer on the power pole. Even though 120/240 circuits are in almost every stick house, people have a hard time grasping the root concept which is only carried forward into a 50 amp service motorhome. Works the same in a motorhome as in a stick house. Only difference is motorhomes do not have 240 motors installed [yes there is always an exception to the rule some place ].

Heh. We're the exception. We have a 240v dryer. And our next unit will have a 240v induction cooktop. It's possible the cooktop will work (degraded) on 120v, but I don't intend to find out.

FWIW, the site has both 30 and 50 amp service at the site I reserved.

LOL - see, in this day and age one has to cover all the bases! However, I sure hope the ones buying these newer MH's understand how all this stuff works.

Thanks Dave. Some of the posts almost indicated that L1 and L2 were tied together.

Dunner,
Many people have had the view that 50 amp service does use the same phase on each leg (ie. L1). Here is the warning that goes with that:

50 amp service provides 50 amps to each leg (L1 & L2) which provides a total of 100 amps overall. If, the same phase (ie. L1) was applied to both legs then while each 'Hot" leg would see a max of 50 amps, the Neutral leg would see a max of 100 amps which is twice what it is designed to handle. This causes overheating and melting of Neutral conductor wire and connectors. The bad problem that is not immediately apparent to the average user is that only the "hot" leads (L1/L2) are protected by the breakers, not the Neutral lead so there is no protection for that issue. Always make sure the 50 amp service you are connecting to is properly wired for 240VAC service before plugging in.

50 amp 240 Volt systems work differently in that part of the total work (current) flows back and forth between each side. The Neutral lead is only exposed to a maximum of 50 amps in a 240 setup which would only happen if everything connected on say the L2 side was OFF and the L1 side was pulling a max of 50 amps. Not going to get into the explanation of how the amps flow back and forth between each side but they do which is how we can flow up to 100 amps total (sum of both sides).

Nite (3AM comes early),
Dave
