Which fuse for my boat?
A fuse protects the on-board electricity from shirt circuiting and overloads. Short circuiting can occur when the insulation of electrical wires is no longer in good order. This may cause a fire. Overloading occurs when a device or an electrical wire is exposed to too much current. Also then, a fire can start on the boat.
Select a fuse based on the highest peak current through the wire or device. The value of the fuse must be slightly higher than the expected peak current. With appliances, you will often find the value of the fuse in the manual.
