ok so i have had the camper (2006 jayco 1206) out twice this yr so far, but as soon as i hooked up to the power this weekend i had heard a pop and smelled plastic burning, shut off the breakers.

installed a 30a main breaker that "back feeds" the bus which by passes the lug.  this to me seems like a better fix than the lug, but i am no expert.  looking for opinions weather to replace the lug or leave the 30a breaker..
thanks
