Default Accessorie outlet: wire gauge for ARB freezer?

I installed an aux power outlet into my tuffy to run my ARB freezer. It is the older 43qt size. Corbets recent thread got me thinking and I was wondering what gauge wire I should use from my aux fuse block to the fridge. This will be a dedicated line, with no other accessories on it.

I know this fridge draws a little more than the newer style. I am thinking 14ag. would be fine. I am running maybe 10 feet of wire tops. I could just over do it and install heavy wire, but that is wasting $$$$$$$

I am not sure what kind of power this thing draws, I think I remember about 4 amps or so?

Thanks!

Drew

For some reason I remember seeing something in my fridge (an Engel) paperwork calling for a minimum of 10 awg.

I'll have to go dig it out and check

Here is a shot of the new 12v outlet in the backside of the tuffy...

It is a Marinco locking outlet, where you can plug the accessory in and twist it to lock it in place and it won't wiggle out.

Cool. Do you need a special plug for that feature?

You and Corbet have both found some really nice 12v outlets!

Matt you do need a special plug to use that feature but it will be nice for the fridge since I won't really be able to keep an eye on it. I found a guy on Ebay and wheel'd and deal'd with him for a while and got three of these outlets shipped for 15bucks!

They go for nearly that a peice at West Marine. I can dig the guys info up if you want.

FWIW, I was on ARB's site and they said the fridges draw 2.7 amps... that is less than a standart headlight, and most factory wiring in my cruiser is around 16ga...

I think my older version is around 4-5amps draw intermitent...

Thanks for the info, and looking that up for me!

this chart seems to say that a wire as small as 14awg would work fine... man, wire has gotten EXPENSIVE in the past few years! That or our dollar continues to spiral out of control!

Doesn't 10 seem like overkill? Just asking, not trying to knock the install sheets

I'm not sure why they call for 10. I think 14 can carry the load but maybe they are concerned about current. I know they had some notes about not using inverters for some reason (regulated current or ) but I didn't really read that part

At 5 amps the difference in voltage drop over 10' is only about 1.3%, that doesn't seem like a significant drop but what do I know

I does not make sense to me why Engel would recommend 10 AWG? With a 2.7amp draw that seems overkill.

I'd run 12 maybe even 14 if all your going to run on that circuit is your fridge. The only reason I ran 10 AWG back to my cargo outlets is for future expansion. Some day I'll probably install an inverter back there.

Just make sure what ever you do, route your circuit so thats its protected form heat as much as possible.
