I have a problem with my leisure battery isolation switch, in that it it is very temperamental, it can take several attempts to make connection. I cannot see anything wrong with it, no debris between contacts etc. However, I am confused about what rating to buy as a replacement. I currently have Three leisure batteries, a total of 330 amps, I may add another 115 amp in the near future.
Switches seem to be rated at 100 amp, 110 amp, 180 amp, 250 amp all continuous rating, or. 350 amp intermittent. Help, totally. infused as to what to buy as a replacement.
