Tripped breaker

[Pat Cassity]

Arrived at park today with my 8 month old 2014 27' International. Temperature 93 outside, 96 inside. Turned on air conditioner and began cooling. 2 hrs later, temperature had dropped to 88 inside. About an hour later, all power went off. Was running AC, one television and a small electric fan. Checked my converted box, all breakers in 'on' position. Stepped outside and checked the breaker on the power box. The 30amp breaker was tripped and very warm. This is second time that the breaker has tripped in high temperatures. Is this to be expected? AC appears to be cooling correctly. All thoughts and advice are appreciated.

Campground 30-amp connections tend to get a lot more wear than their 15- and 20-amp or 50-amp connections and aren't replaced as often as maybe they should be. All it takes is a plug that's loose in its socket to create increased resistance and increased heat that can trip your breaker. Last time that happened to me, I got out my trusty 50-to-30 converter and plugged into the adjacent 50-amp connection. I was still drawing 30 amps (25 actually, I think) but with no problems because the plug fit tightly the way it's supposed to.

Thanks Pro. Checked the plug and it was a bit 'loose'. Unplugged it and made sure it was plugged back in securely. No problems so far.
