Fuse & breaker rating for Lippert stabilizer jacks?
I just completely rewired all the wiring in the A-frame area on our TT. Lots of corrosion and bad connections so I installed a water-tight junction box for the splices and the two mini circuit breakers.
In the process I found that our two Lippert electric stab. jacks have #14 gauge wire and they are connected to the 30 amp mini circuit breakers in the A-frame area. The rear jack has a 30 amp breaker mounted on the frame's I-beam but the front jack does not. Each jack actually has two 30 amp breakers in series. A 30 amp breaker on #14 wire is not good at all. A motor could get overloaded and damaged and/or the wire could be damaged.
Lippert specifies minimum #10 wire and then a 20 amp fuse in series with a 6 amp auto reset breaker. Not sure exactly why they want a fuse and breaker in series unless one is for overload and the other short circuit? Question is, can I use just a breaker or just a fuse (at the A-frame location)? I installed a 20 amp fuse for each motor temporarily until I figure out what to use.
