Yes there should be an in-line fuse. If there is not an in-line fuse and there is a voltage spike in the vehicle the fuse will pop and disable the circuit where as if there was no fuse the accessory or mechanism could be destroyed.
As above suggests, the fuse must be put in series. If it is in parallel, the fuse should blow immediately on completing the circuit, because it is effectively a short, which will cause large current flow into the fuse until it blows. Never, never, never put a fuse in parallel with whatever you want to protect - that defeats the point of the fuse.

∙ 11y agoIf you were to connect a fuse or circuit breaker in parallel with a circuit, it would create a short circuit and immediately melt (fuse) or trip (circuit breaker). These devices must be connected in series with the load.

∙ 11y agoParallel with regards to electrical circuits means that one or more cables with the same connections run along side each other.
If a fuse in parallel were to break due to a fault conditions the electricity would still have at least one other path available to it to travel to the other side of the fuse... making the fuse useless.
Fuses must be inserted in series with a circuit. This means that there is no bypass available to the electricity.
If you are in doubt please contact an electrician.

It is not. Fuses, switches or circuit breakers must be in series to the current flow, as they are designed to interrupt the current flow when necessary.
Since these devices offer no resistance under normal conditions (switch closed, fuse intact), installing these in parallel to the load will cause a short circuit.

When you open a fused disconnect it just looks like they are in parallel. It is the physical positioning of each leg of the incoming supply. Each fuse is in series with the corresponding leg of which there are two for 120/240 volt installation. Visualize the supply coming into the top of the switch and leaving the bottom of the switch.
Breakers are restricted to the same condition. Because of the bus bar construction in distribution panels physically the bars alternate down the length of the panel. Starting at the top, they alternate L1, L2, L1, L2 all the way down.
With this configuration two pole breakers can be installed to get the required 240 volts which is obtained across L1 and L2. Single pole breakers are used from L1 or L2 to neutral for 120 volts.

Remember one thing my brother, electric current always takes easy path (lowest resistance path ).

How is a fuse different from a circuit breaker?
A fuse is used one time and replaced. A breaker can be re-set.
What is the range of circuit breaker that can be used for a 24V DC equipment?
Use a fuse
What one is better fuse or circuit breaker?
IMO it would be because the circuit breaker has the possibility of going bad and not working (allowing a short to move through the device), but fuses blow (cause a break) no matter what if shorted.
Why does a fuse blow or circuit breaker trips?
Both devices are safety measures for the electrical circuit. The home fuse is a glass affair with a burnable core. If the core melts, the circuit opens. The circuit breaker does the same thing, but is a "reset" device, meaning that it can be used over and over again. The fuse is replaceable, but not "reset-able." Both systems are used in modern homes, but the fuse system is being replaced by the circuit breaker system.
Which can prevent a circuit from overloading?
In most appliances the single thing that prevents an overload is the fuse. In modern electronics there are various devices that can be used for power management which can limit the current drawn by reducing the load voltage. see: http://en.wikipedia.org/wiki/Current_limiting

How does circuit breaker or fuse protect the house from fire?
The fuse is matched to the size wire in the circuit the breaker/fuse it is protecting. For instance, a 20 amp breaker/fuse is used in combination with AWG 12/2 wire. A 15 amp breaker/fuse would be used with AWG 14/2 wire. If there is too much current flow in the circuit caused by either overloading the circuit or by a short in the wires the wiring would overheat and catch fire if not for the breaker/fuse. The breaker/fuse is designed to detect this and to trip or blow and shut off all power flowing to that circuit and prevent a fire. This is why you should never install the wrong size fuse. Put a 20 amp fuse on a 15 amp circuit and it would not protect the circuit as it should.

Which electric element should be used so as to open the closed electric circuit?
A switch, circuit breaker, fuse, or switching transistor can do that.
In the electrical circuit of a house the fuse is used?
A fuse/breaker is used to protect the wiring within the home for overheating and catching on fire. When the fuse/breaker detects an excess flow of current beyond the range of the fuse/breaker, within a circuit, it will blow/trip to shut off the flow of electricity in that circuit thus preventing a possible fire.
