All ActivityMost RecentMost LikesSolutionsRe: Breaker Panel Help PleaseYou have lost a phase (one leg) of you service. Unlike homes, most RVs have split panels. Power comes into your 2 pole 50amp breaker and 1 pole feeds to the left and 1 pole to the right. The reason you have a A/C breaker on each side is, the AC is 220 and needs 120 from each side of the panel. Check the power at your ped to make sure you rv is getting 220 and if it is. Replace the 2p/50amp breaker. Of course, please disconnect from the ped, before replacing the main. You can purchase a replacemt breaker at Lowe's or HD. If you are uncomfortable with electric, please hire an electrician like myself
