Fuse for ARB Fridge

Have not had any experience with the ARB fridge but I am assuming the reference to a 5A fuse is for the internal fridge fuse ( or is it in the ciggy plug holder supplied?) not the exterior fuse on your supply cable. The fuse on your new loom is to protect the cable not your fridge.

Let me explain the basic principles of fusing.

Where there is a single supply...we fuse to protect the down stream CABLING.

So as long as the fuse is larger than the current demanded and smaller then the current carrying capaity of the cable you are safe.

If an appliance requires a fuse, it should be either in the appliance or in the appliance connection cord..preferably in the appliance..and that fuse protects the down stream load.....that that is beyond the fuse.

You do not need to have a fuse both ends of a cable unless there is a source of supply both ends...like in a dual battey situation.

As for this need for a dedicated feed.....ahh take that with a grain of salt.....it may have been true if you where running 6mm automotive 4.5mm2 as a dedicated fridge feed........but if if you are running #6 that should support more than a fridge no problems...

#6 is about 13mm2, and rated at 125 amps.....over the length of the car you should be able to pull 40 or 50 amps out of that with little or no issue with voltage drop.

If you want a switchboard at the place where you have your fridge to deliver other loads as well ...that should not be a problem
