Wiring Air Conditioning to 30 amp Panel

Hello,

I have a 1985 Jayco travel trailer that I'd like to install an air conditioner in. The camper is already wired for A/C with a wire from the ceiling to close to the breaker box. I took a look at how the breaker box was wired and I think it needs some work. It's a two breaker box with a single screw for the black hot wire on either side (one for each breaker). The left side has a double 15 amp. If I need to add a 20 amp breaker it has to go on the right. Can I jumper the hot wire over to the right breaker to power it? Or should I reconfigure it with a 30 amp main breaker going to a sub panel with multiple breakers? How would these be setup from the factory?

Thanks for your help,
Jeremy
  • You need to purchase a thin breaker to go in the right side. This will give you protection for the new AC unit and supply power to what is currently fed from the right side. The buss should be either all ready jumpered or is one piece.
  • The breaker should already be powered by the rail since it is a 30 amp you only have one hot side. Put the breaker in and the breaker will be hot just hook up the 12ga wire
