When is it good to fuse power supply and load?
In the event of a fault that blows the fuse, the power is isolated to where it entered the circuit, thus the whole circuit is protected. Using other configurations could allow the supply voltage into other parts of the circuit unexpectedly. There are situations where it’s good to fuse both the power supply and the load, but that’s another question.
What causes the fuse to fail when I turn the key to the start?
If the WHITE wire coming off terminal “S” is shorted anywhere between the ignition switch and the clutch/brake switch and the attachment clutch and solenoid it will cause the fuse to open/fail or if “clutch/brake switch or “attachment switch is shorted it will cause the fuse to fail/open whenever the key is turned to the start position.
What happens in the event of a fuse blowing?
In the event of a fault that blows the fuse, the power is isolated to where it entered the circuit, thus the whole circuit is protected. Using other configurations could allow the supply voltage into other parts of the circuit unexpectedly.
What happens if the fuse is before the switch?
If the fuse is before the switch, it will always be “hot”, and will potentially be a shock hazard. For plug-in equipment the order is less important, as you can unplug the equipment while changing the fuse.
When to put the fuse before or after the power switch?
In most cases, I would prefer to put the fuse immediately after the main power switch. That way, with the power switch off, both terminals of the fuse are “dead”, so there is no shock hazard while changing the fuse, providing the switch is off. If the fuse is before the switch, it will always be “hot”, and will potentially be a shock hazard.

Where are the fuses in a Range Rover Evoque?
Cigar lighter (power outlet) fuses in the Land Rover Range Rover Evoque are the fuses #52 (Cigar lighter), #53 (Cubby box accessory power socket), #55 (Rear console accessory power socket) and #63 (Luggage compartment accessory power socket) in the Passenger compartment fuse box.
Why is the fuse the first thing a power supply hits?
The fuse should always be the first thing a power supply hits when it gets to a circuit. The reason is pretty simple. In the event of a fault that blows the fuse, the power is isolated to where it entered the circuit, thus the whole circuit is protected.
