fridge amps

96terrano · 21-08-2013, 20:08

Ok so about to wire my 12S socket for my little Hyundai, what's the best amp wire to use for the fridge power feed? I've already got wire for the charging circuit as it came with the SCR for charging my AUX battery in the spare wheel well, but will need a permanent live for the fridge

Just want to know what the best amperage of +ve and earth cable I should use

Thankies!

depends on the fridge, absorption or compressor type ?

What the rating of the fridge ........you will find that on the Data badge

Then you can work out what size of cable / fuse you will need

I was going to ask Ryan if he knows if what the Delta T is between Super heat & sub cooling ......but that may be a Question to far

Caravan fridge pull upto 10 amps

15amp fuse is fitted

Use 20amp cable

actually, i'll just use a 12v cool box when i go on camping holidays, they're about 10/15 amps i think, designed to run off a standard 12v ciggy lighter so will store that in the trailer

current ( in amps ) is voltage divided by resistance ....... or power in watts divided by voltage .

i only asked as i fitted compressor type fridges in motorhomes i worked on last week,
don't know how they slept for the noise on a night !

Don't leave the fridge or cool box running direct from the car battery without the engine running.
