    Where Do I Need a Fuse Holder?

    Where Do I Need a Fuse Holder?

    Fuse holders allow you to insert a fuse into an electrical circuit to protect the wire from the damaging effects of too much power flowing through the cables. The fuse is a replaceable device that will 'blow' to stop the flow of electricity in the event of an overload. If a fuse blows in a circuit, it is critical to determine what caused the problem before replacing the fuse; otherwise, the fuse may fail again.

    Fuses (in fuse holders) should be installed on every cable as close to the power source (the battery) as possible. When a wire is divided or spliced into smaller wires, each one should be fused. A single wire is protected by a single fuse holder. A fuse (holder) should be the correct size. Larger diameter cables need larger fuses, whereas smaller diameter wires require smaller rated fuses.
