Connecting the neutral and earth at the fuse board provides an additional safety measure in the event of a fault. It helps to ensure that any stray current has a low impedance path to earth, protecting against electric shocks and creating a stable reference point for the electrical system.

What fuse controls wipers on transit connect?
I found it was a Yellow 20 Amp fuse (Fuse 56) on the Fuse board. This can be found by opening the glove box, and squeezing inwards the sides, this then drops down to reveal the fuse board. NB this was for my Transit Connect 2003.
Why do outlets have 3 holes?
Live, neutral and earth. The supply is carried on the live and neutral, and the earth normally carries no current, but if there is a fault the earth is there as a safety factor and in some conditions it carries enough current to blow the fuse and make the circuit safe.
Do you connect a fuse to the live wire or the neutral wire?
A fuse is typically connected to the live wire in a circuit. This is done to protect the circuit from an overload or short circuit, as the fuse will blow or trip and cut off the current flow if there is an issue.
How you provide earthing by three pin plug?
The three pins are live, neutral and earth. The live and neutral carry the current, and the earth should carry no current. Its function is to connect together the external parts of all pieces of equipment so that it's impossible to get a shock by touching two items at once. Another function is to connect the external parts to an earth rod and to the gas and water pipes in the property. Another function is that if an internal fault allows a live wire to touch the case, enough current will flow to blow the fuse or trip the circuit breaker. So in different ways the earth pin/wire provides an important safety feature. In Europe the earth wire is coloured green and yellow.
Why the fuse is placed in live wire only?
So that the live wire is isolated when the fuse blows. If a fuse was placed in the neutral, the equipment would still be live when the fuse blows.
If we connect Fuse wire to neutral how will it affect safety?

Is safe to connect fuse in neutral?
No - absolutely not!Fuses are there to protect against overcurrent in the event of a fault. The neutral is connected to earth at the supply company's source, usually at the transformer, so the difference between neutral and earth at the consumer's premises will only be a few volts (this is due to voltage drop in the supply cables). The fuse should be in the live, so if there's a live/earth or live/neutral fault, it will blow. If it was in the neutral, it would still blow for a live/neutral fault, but it would leave all wiring in the appliance live. However, for a live/earth fault, there would be no protection apart from any fuse further upline - probably of a higher rating, so there's a risk of fire and/or electric shock.Early electrical installations had fuses in live and neutral. The problem here is that if the neutral fuse blew first, the whole circuit would become live - so there should never be a fuse in neutral - under any circumstances.Always fit a fuse appropriate to the load current, and also ensure cabling is capable of taking the load current safely.I have come across several instances in Chinese consumer electronics of an internal fuse in the neutral. Amazingly, this junk carried a CE mark!
What happens when fuse is given to neutral?
A fuse should always be inserted into the line conductor, never the neutral conductor. If a fuse has been inserted, inadvertently, into the neutral, an overload will still operate the fuse, but the line voltage will not be isolated from the circuit -thus presenting a shock hazard. Furthermore, it will not protect against an earth (ground) fault that occurs in the circuit.

What is use of neutral link?
In a MEN (Multiple Earth Neutral) system, the neutral wire is connected to the earth wire at the switchboard. This is the neutral link. From an electrical point of view the neutral pin and the earth pin in a power socket are at the same potential but from a safety point of view they are different. A residual current device (RCD) (or earth leakage core-balance-relay(ELCBR)) sits in series with both the active and the neutral feed and a leakage from either wire to ground (via a human or water leak in a washing machine etc) will trip the circuit breaker that is in the RCD.Another AnswerFuses or circuit breakers must be inserted into the line conductor, never into the neutral conductor. However, if we need to isolate the circuit, we must place a break in both the line and the neutral conductors. We can achieve this for the line conductor by, for example, removing the fuse. To achieve the same with the neutral conductor, we can open the neutral link, which is simply a short length of conductor inserted between a pair of terminals in the neutral.
What is neutral inversion?
If the consumers metalwork is not bonded to the neutral a direct earth fault would result in a current of 20 amps flowing.This fault current will probably be carried by a 16 amp fuse or citcuit breaker and returned to the neutral via electrodes this will force the neutral conductor up to a potential of 200 v above earth this is known as neutral inversion
What are the procedures to connect an electricity service connection to the Earth?
Purchase a ground rod from an electrical supply. Drive it into the ground just outside where your service is located. Install a ground cable from the neutral bar in the fuse box to the ground rod and clamp both ends. Voila, you have done it!
How do you wire 220 volts to fuse box?
To wire 220 volts to a fuse box, first ensure that the power is turned off at the main circuit breaker. Use appropriately sized wires (typically 10 or 12 gauge) and connect two hot wires (often black and red) to the designated terminals in the fuse box, along with a ground wire to the grounding terminal. If your fuse box has a neutral, connect the neutral wire (usually white) to the neutral bar. Finally, secure all connections and replace the panel cover before restoring power. Always follow local electrical codes and consider hiring a licensed electrician if unsure.
Why fuse is not used on the path of neutral?
Neutral must never be cut off.
What does the fuse do in a three-pin plug?
The 3 pin plug is used to connect (and eventually disconnect) various devices requiring an AC power supply to and from the main power supply.As the name suggests, the 3 pin plug consists of three pins :-Longer one, usually on the top for most standard plugs : is the earth [ E ]Left pin (Usually) : is the Line connection [ L ]Right pin (Usually) : is neutral [ N ]Next to the pins, on the plug, the three pins and their respective function is given by E, L and N.
