Electrical question please.
Ok I will admit it. I have had my MH for 5 years and have gotten along great with it. My question is that it is a 1996 Damon Intruder and it is 50 amp. Now is it 50 amp 110 volt or 50 amp 240 volt? Th...

Then L-1 is providing 13.5 amps to the air conditioner (one of them) so is L-2 (to the other) but due to the phasing of the two legs.. The neutral is carrying a grand total of nothing at all, if it were to break, you'd never know. OF course that only applies in a perfectly balanced system (not practical)
)
It's important to note that the theoretical loss of a neutral never goes as well as one that breaks, or develops unusually high resistance, in the real world. Several times in my career I have gotten the service call where the customer is totally baffled as "the lights got real bright, and now I lost a lot of electronics and seem to be finding failed appliances everywhere I turn". When a panel, or service neutral is broken, or highly resistant, there are series connections made between various branch circuits, and the result is 120V circuits that end up with values higher than 120 but less than 240. It typically is quite damaging and expensive. If you want to understand it on paper, draw two 120 volt lighting circuits, one per "phase" with just a single incandescent lamp on each circuit. Now cut the neutral at the panel and track the series circuit you created. That's why it gets ugly when you loose a neutral.
