it says Micro - which I would assume is the microwave - maybe see if you can unplug the microwave and try the breaker again.
could also have one of the leg's on a GFI plug came loose and shorting out causing it to pop the breaker - remove the gfi plugs to check them if the micocrowave isnt the one causing the breaker to pop.
make sure you unplug the main power off of the trailer prior to working on the 110 power so you dont get shocked / electricuted or cause a fire
do not keep popping the breaker on to reset it - you have a problem and need to figure out where the problem is - it could cause a fire
i know on my trailer when one of the GFI plugs pop - it pops the microwave, A/C and all the GFI plugs - maybe yours is wired the same
