Hi

The last class I attended disagrees with the 100 amp idea.

A 240 Volt 100 amps stove requires a 100 amp breaker.

The amperages doesn’t multiply the wattage does.

In simple math 50 amps at 120 v = 6,000 watts

50 amps at 240 V = 12,000 watts.

You can produce more “work” at the higher voltage than at the lower voltage without changing the amps.

Here is a picture of the transformer used in the U.S. for a 240V service.
As you see when you add load to the 120V legs as you increase the load on L2 the circuit become a 240V circuit and produces more “Work” for the same amps.

Remember we are working with Alternating Power or AC so when leg 1 is + Leg 2 is – and will only carry 50 amps without tripping the breaker. When leg 1 becomes – the leg 2 become + and can only carry 50 amps without tripping the breaker.

I f you load only one leg to 50 amps the neutral will carry 50 amps but as you add load to the other leg the neutral carries less.

What happens to your trailer when you lose the natural if you are carrying 50 amps on L1 and 20 Amps on L2 the current for the high load flows thru the appliance with the lower ability to carry the load and the little one like your TV becomes a toasted critter.

In my case when I lost the neutral I toasted the Converter and the TV lift the AC’s didn’t sustain any damage.
