Hi Everyone,

Apologies if this is covered elsewhere, but I couldn't find it!

This one is for the 12v gurus out there. I am wondering whether it is possible to use an extension lead (10m) from my rear anderson plug into what I have called a "hub" (like one of those premade control box panels) where there are numerous outlets for a campsite (usb/cig).

I take it that inside this hub would its own fusebox so the outlets are individually fused, I guess I'm just wondering whether anyone can see any issues with this setup?

I know I could just utilise a battery box but I don't really have the room for the box in the cargo area

Thanks everyone.

Yes you can plug an extension into the ando. Make sure the wire size is minimum 6mm. Just make sure the supply to the ando is fused at the car battery.

Greg make no mention about running a 3 way fridge, only lights which I would assume are LEDs so 6mm is a bit of an overkill and he could get away with 1.5 or 2.5 mm.

Kazza, are you talking sq mm or mm diameter including insulation which is the automotive convention?

And what is hanging off the charger? A couple of USBs? Maybe more. If they are all pulling 2.5 amps, then I think you'd need 6mm quality automotive to the hub.

6mm as in automotive 6mm not 6mm2.
I'm saying 6mm as the car ando will have a minimum of 6mm wired in it. And it is also better for crimping into an andersn plug.

Should be no problem. Things to check, make sure the anderson plug is fused. You will need 6mm2 sheathed twin core., anything less and you will have too much voltage drop, or should I say current drop. Also not all hubs fuse all circuits individually, some fuse in pairs, some use a common circuit breaker.

As has been said. If he's only running led lights and chargers then he's got a low current draw.
6mm would see no volt drop if the lead is kept short. You get current drop haha. In fact if the voltage is lower you'll get more current draw. It doesn't matter how the circuits are fused inthe hub. The fuses are to protect the wiring. And the anderson wiring only needs to be fused at the car battery.
