Ripca Standard Blade Fuse Box With Positive & Negative Busbars & LEDs - 12 Way
This fuse box contains a group of twelve fused circuits fed from a common busbar input, plus an integrated 12-way negative busbar for connecting all the return cables, eliminating the need for an external negative busbar. This ensures all connections are accessible in one place which makes fault-finding easier and provides a very compact, centralised fusing and distribution solution.
Each circuit also has a red LED that lights when the fuse blows, enabling you to quickly identify the affected circuit.
 
Please note that in order for the red LED to light, a very small, limited current passes through the circuit so you may still register continuity across the fusebox terminals when a fuse is blown or no fuse is in place. This limited current is completely safe but may cause connected LED lights to glow faintly (since they require such low current to operate).
