Fuse Box Install

When wiring a fuse box to the leisure battery do I need to add an inline fuse? Between the fuse box and the battery?
 
YES,

ALWAYS fuse any cable coming from the battery.

Safety first =]
 
What size inline fuse would I use going to a 12 gang fuse box?
 
show us a pic of the box, or a link. and what size feed cable to the fuse box are you using?

what do the fuses total up to if you have any?

I don’t have anything wired into it yet but hopefully by next will be;

Circuit with 4 x LED lights
Circuit with 2 x LED lights
1 circuit with twin USB socket

I don’t currently know what size fuses I need for the above circuits!

The cables I have to install the box are the ones supplied by travelvolts that came with it :thumbsup:
 
The size of the fuse is set by the size of the cable usually, if you use 50 amp cable use a 40 amp fuse if you use 100 amp cable something like an 80 amp fuse so you can never overload the cable and if something shorts out the fuse will blow and everything safe
The stuff you are connecting is all pretty low draw so fuse from 5amp for the lights and maybe 10-15 amp for power outlets ?
 
close as possible to the battery (source of a massive amount of current) . . . .

in case there was a catastrophic failure ! . . . . ie road traffic collision that crushed the supply cable causing a short circuit....

the power stored in the battery would heat the cable and could start a fire.



have a look at this guy, his installs are amazing, just pay attention of the power and fusing side of things. . . . .

whether its ICE, inverter or a fuse box the implication is the same.... its just down to the required power/wattage, that will determine the gauge of cable required and what fusing is required to protect the cable and devices.

What Dellmassive says.

The leisure battery is a massive source of power. If you put the fuse close to your distribution fuse box, then a fault on the cable from the leisure battery before the fuse could result in a huge amount of power being dissipated through that cable - resulting in fire.
With a fuse very close to the leisure battery, you are protecting not only the fuse box and what comes after it, but also the length of cable from the leisure battery to the distribution fuse box.

My leisure battery is under the driver's seat. The master fuse (actually 2 of them) are mounted on the driver's seat base. So the cable from the leisure battery to the fuse box (halfway down the van in my case) is protected by that fuse.

Thread resurrection......With the DC-DC charger now installed under the drivers seat, I'm running 6mm to a 6 way fuse box, with lights, USB sockets, fridge and pump/tap. The cable will be 30A fused near the battery.
Any advantage in having the fuse box nearer the front of the van (reducing 6mm cable length)? Plan is the have it and negative bus bar in unit below C pillar. I'll have a kitchen pod, crossways on, that I want to be removable, so don't want it all in that.
Appreciate your input.
