Posted - 12 May 2014 : 13:37:17 Can anyone tell me what size (amps) split charge relay I should fit to my 23ft Norman. I have a 110amp leisure battery that I want to use. I will only be using the internal 12v lights, a 12v small television and a 12v cool box.

Posted - 12 May 2014 : 18:46:17 A split charge relay needs to be able to carry the full charging current. This will always be far more than the drain current.
Think about 40 amps unless you have something really special in the charging department. They come in for a bit of hammer so best to spec well over the minimum.
They can become unreliable if the contacts arc and spark. Don't forget to put fuses in the right places or you easily start fires.
This is a reasonable installation..
Have a look at a Voltage Sensitive Relay as a far safer and all-round better solution.
