12v Questions

[Tully80]

Hi all
I am sure these have been covered already but much of it is over my head wondering if someone had a quick simple answer for me, as I am no sparky. I have a T6 which I am part way through converting. I bought a leisure battery and a Victron DC-DC and had an auto spark install it but was not cheap. So I now have power from the starter to the leisure battery under the seat so job started.

Two quick questions.

1. I have a Victron 240v to 12v 30 amp charger to wire up now, the run is about 1 meter. Wondering what diameter/AWG cable I would need and if this needs a fuse on the positive wire?

2. I have a Sanjo SVR50L fridge to connect up too which has two wires coming out the back presumably to connect to 12v. From what I can tell this connects into my mini fuse board which will draw off the leisure battery. My question is can this also run off 240v or does it draw off the leisure battery which when hooked up to 240v is then topped up by the victron 240v -12v. In the instruction book it seem to mention a rectifier which from what I can see switches between 12v and 240v?

Any help on either of these would be great thanks
Dave

Your Victron 240v charger will be powered from your consumer unit connected to the EHU and will just be plugged in to a socket run from the CU or hard wired into the 5A outlet in the CU, but you have to cut the plug off to do that.
The cable to the LB from the charger come as as part of the Victron charger and you connect that to the LB. No need to worry about sizing cables.

The Sanjo fridge does indeed connect to the 12v fuse box. Keep the run as short as possible. They can be temperamental with voltage drop. Some people wire it direct to the LB with an inline fuse. I have a Dometic fridge wired into fuse box and have never had a problem.
It draws, as you say from the 12v LB which in turn recharges via the dc-dc or the 240v - 12v on EHU, or solar.

Cheers for the response much appreciated. The 240v victron didn't seem to come with any cable to connect it so I've bought an AWG5 16MM cable on Amazon and I'll pop a 100amp fuse on it I think?
Perfect ill wire the fridge to my fuse hub with a short run cable, any idea what amp spade fuse I should run it through?

These are the cables I bought for the 240v to 12v, will they do?
