We are currently in a 30amp site. As we use various electrical components, the "brain" will show us how many amps are being used. What happens if we exceed the 30 amps available? Say, two small hea...

Some of what happens may depend on how your 50A to 30A adapter/cord is wired. There are two choices.
- It may be wired so that one "leg" is completely ignored. If wired this way one of your AC and possibly some of your outlets will not work
- If both legs are wired together, the worst case is that you will trip the breaker at the pedestal. You might even be able to run both AC units simultaneously (as long as they don't start simultaneously) or run both of your heaters
I have never seen a 30 male to 50 female where the one hot on the 30 was only wired to ONE hot on the 50 amp side.
Said another way, a "proper" 30 to 50 always connects the single hot on the 30 amp male end to both hots on the 50 amp female end.
Would love to see a link to one wired any other way!
