That's a pretty good indication of how much load regular bulbs draw.

Seems like all the rigs built today are 100% LED bulbs. Slowly converting our house to all LED.

I disagree, 30a service is still 220v thus two hot 30a legs. but load still has to be distributed evenly.

All 30 amp service is not 220v. 30amp service in RV parks is 110v. When using 30amp service in your RV one 30amp hot lead is bridged via the dog bone adapter to both hot leads in your 50amp cord to energize both busses in your breaker box.

Powerhaulic, yes 30 amp Range and Dryer outlets are indeed 240 Volts with two hot leads, but a Jim says, RV outlets are a different breed, with 1 hot 120 Volt, 1 neutral, and 1 ground, where as a 50 amp RV outlet is 2 hot 120 volt legs, 1, neutral, and 1 ground.

I had thought 30A was two pole until I ordered a 30a RV box to wire into a friends house and saw the reciprocal diagram called for a hot, neutral an ground. Then confirmed it with 30-50a adapter as mentioned above.
Question I have, is the 50a - 25a per pole or 50a per pole/leg?

According to the Progressive Dynamics tech , each leg is 50 amp and hence 2 50 amp breakers , dog boned together in your breaker box, giving 100 amps total, and 50amps each side of the box.

Thus the reason you can run so many more things in a 50 amp unit vs a 30 amp unit.
