Swapping cig plug for Anderson connectors

[Steve_P]

I'm swapping the cig plug on my Dometic CF 25 to Anderson power pole connectors. The plug on the CF 25 has an internal 8 amp fuse, according to the manual. Has anyone who's done this bothered to put an inline fuse holder on the downstream side of the connector?

If the freezer is pulling over 8 amps there would be a bigger issue, I think we have a 5 or 6 amp on ours and it has been fine.

IMO fuses are your friend. They prevent fires first and equipment damage second.

I would put a nice, neat, soldered & heat-shrinked 8A fuse as close to the Anderson connector as you can. No use in second-guessing the engineer that designed your Dometic.

When a fuse blows, it's your chance to figure out how you screwed up.

I did not fuse my Dometic cord when I cut the cig plug off. I didn't even think of it actually. I fused the circuit with an inline right at the battery and called it good. You should have a fuse somewhere, but inside the cord seems like the place a manufacturer would use because they can't actually fuse the true source.

That's what I was thinking. The dedicated circuit already has a fuse at the battery, currently 15 amps but it could be less if needed. The panel mount I got has 2 circuit capability and that had me thinking about other possible uses.

Anyone ever try powerlet plugs? They work good on my bike

 

[Steve_P]

Won't know for sure until I cut the power cable but it looks like 14 gauge and should be able to handle a short burst of 15 amps if the absolute worst happens. If it's not 14 I'll downgrade the fuse at the battery.

When I rewired my Conqueror I put in a small Blue Sea fuse panel that had both pos and neg fuses. I think I had a 10 amp for my fridge but it might have been 5.

I've got Blue Sea in the Jeep now with fuses on both sides again. Another fuse for each leg to my ham radio plus one big honkin fuse from the battery to the Blue Sea panel. So my radio has 5 fuses...

The real question is, why have disconnects at all? In both of my fridge installs, I've just cut the plug off and hard wired the cord. On the rare occasion that I remove the fridge, I just coil the cord and zip tie it out of the way. In the wife's car, it just coils into a storage box. If you are moving from car to car, you won't have the right connectors once you modify your cord, and a second cord is in the ballpark price of Anderson's anyway. Most of the time the fridge comes out, it gets plugged in inside the house, I've never once wished I had a 12v cord other than the hard wired one.

I used to swap from trailer to truck to car to house pretty often depending what we were up to.
I don't think that thing was ever off.
