possible electrical problem

hey all,
not sure where to start. so here goes. the other day was sitting in the trailer had the air running and tv. all of a sudden the air tripped off. along with that the microwave went off also. the tv and all other 110 circuits were still up and fine. went out and checked the box and nothing was tripped. reset just to see if that would help. everything started up like normal, a few minutes later tripped again. this time when i went out there there was a distinct electrical smell coming out of it. now comes my possible concern. i put a second air on the trailer about a month ago. is it possible that this is a problem. maybe i am pulling too much of a draw on one leg of the system. anyone have any ideas as to what may be the problem. i am currently hooked up to the site next to me until the box gets fixed. thanks

pep1977,

Is everything working OK now that you are hooked up to the site next door?

My money is on the power supply pedestal, the electrical smell is the give away.

pep1977,

Well, that makes for a good question, I guess you'll have to wait untill you get back to a 50 amp service.
We only have the one air and no W/D. So far 30 amp or 50 amp works for us.
You might be drawing a little too much power out of one leg of a 50 amp service.
Strange it wouldn't trip the main breaker and only cut half of the power to your unit.
And no breakers tripped in your unit? Sounds like it might also be a Park problem.
Let us know what you find out.

Sometimes half of a twinned breaker will trip, and not have the spring strength to trip the other lever, always flip a suspected breaker all the way off with pressure than turn back on.
Also remember that breakers and fuses trip and blow (most of the time) for a good reason, when this happens, check for the cause. The burned smell, as I said before, is the indicator in this situation.(I think.)
Also remember that a blown 30 amp fuse in your converter will indicate reversed polarity, as the breaker feeding the converter is only 15 amps-maybe 20, I forgot, but the breaker would trip first if the converter drew over amps, a 30 amp fuse indicates another cause. I think I am right on the fuse being 30 amps.
OK, I'll leave you guys alone now.

Note; Pep1977 wrote and stated that the buss bar was discolored, so it might have been that Two heavy loads were on the same buss bar, might want to move one 20 amp breaker for the second A/C over one spot. Hard to tell what he has there without looking.
