30 amp / 50 amp
We're considering a new FW and a couple of the options are upgrading the single AC to 15k with 2nd AC prep (I believe the prep is standard). There is also a 30 to 50 amp option. First question; if I...

Since very few RVs have 240V appliances the simple explanation is that you have 2 50A circuits for the RV which is a lot of power. Some loads on one circuit and the rest on the other circuit. And yes they are protected by a dual ganged 50A CB for safety. If you overload one 50A circuit both will trip disabling all power in the rig.
So why is it called 50A when it has 2 50A 120V capability or 100A total? The circuit description is 120/240V, 50A, 4 wire, 3 pole, 60Z. The 50A designation refers to the higher voltage (240V) and indeed 50A is the maximum a 240V appliance could draw. The plug is also a standard household plug and circuit. And some homes use this plug for their 50A ovens which use both 240V (heating element) and 120V (light, etc).
