Carbest 12 V / 24 V power distributor with 12-way fuse holder, LED indicator and negative bus - for motorhomes and boats
- Carbest power distributor for 12 circuits with an LED next to each fuse and an integrated negative bus. Up to 30 A per circuit and 100 A in total, voltage up to 32 V. Fuses are not included.
The Carbest power distributor with 12-way fuse holder is a compact fuse and distribution box for low-voltage wiring in a motorhome, caravan, van or boat. From one place you distribute positive power to up to twelve loads, each through its own fuse, and collect the negative wires on the integrated negative bus. A red LED next to the slot shows at once which fuse has blown.

Twelve circuits in one box
- Up to 12 separately fused circuits
- Load up to 30 A per circuit
- Total load up to 100 A
- Operating voltage up to 32 V, for 12 V and 24 V systems
- Clear plastic cover included

LED and negative bus
- A red LED next to each slot signals a blown fuse
- Integrated negative bus for the minus wires
- Screw terminal for every circuit
- Mounting holes in the base, 4 screws included
- Over 70 labels for marking the circuits
What it is for
The distributor keeps a 12 V or 24 V installation tidy. Instead of several inline fuse holders you get one box: you feed it from the battery and run separate wires to lighting, water pump, fridge, heater, USB and 12 V sockets, roof fan or radio. Every load gets its own fuse matched to its current draw and wire size. With the negative bus the minus wires also meet in one place, which makes fault finding easier later.
Installation and choosing fuses
- Screw the box to a dry, flat surface with the four screws supplied.
- Connect the positive supply cable to the input terminal and the ground cable to the negative bus.
- Connect each load to its own terminal and insert a fuse rated for the wire and the device.
- Respect the limits: max. 30 A per circuit and 100 A for the whole box, even if the sum of the fuses is higher.
- Protect the cable feeding the distributor with a separate fuse close to the battery.
- Mark the circuits with the supplied labels and fit the clear cover.

Frequently asked questions
Are fuses included?
No. You buy the fuses separately and choose them for each circuit.
Can I use the distributor in a 24 V system?
Yes. The maximum operating voltage is 32 V, so it works with 12 V and 24 V systems.
How does the LED indicator work?
When a fuse blows, a red LED lights up next to its slot, so you see at once which circuit is down.
How much current can the whole box carry?
Up to 100 A in total and up to 30 A per circuit.
Can I connect the negative wires of the loads to the distributor?
Yes, that is what the integrated negative bus is for.
