[C320-list] Push Button Circuit Breaker

[danny jensen]

Jeff,

   1. I wanted to confirm the 10 amp breaker is on the AC side of of
   charger?  I would open the main panel up and look at the AWG size of the
   wire feeding the old 10 amp AC breaker. If it is 16 awg or lesser eg 14 awg
   etc., then you are good to go with the 15 amp AC breaker.
   2. Good Idea to use the MRBF fuses on the battery side and maybe clean
   up some other direct connections to the battery while you are at it by
   buying a double MRBF.
   https://www.bluesea.com/products/2151/Dual_MRBF_Terminal_Fuse_Block_-_30_to_300A/FAQ.
   Take a look at the DC wire size to the battery and size the fuse big enough
   to protect the DC wire from charger to battery not the 40A charger.
   Otherwise you will be adding unnecessary voltage drop.  Take a look a the
   article below eg. #8 wire =~ 60amp MRBF fuse / #6 =~ 80Amp even though your
   charger is 40A.
   3. If you are thinking about solar charging, now would be a good time to
   set up a small backboard near the battery charger for you solar charger.
   I"m using my battery charger DC wiring for my solar charger.
