Why is it important that the live wire not the neutral wire is connected to the fuse?
Suppose there is a fuse which is connected to a live wire and it breaks some day because of excessive power supply. The light goes off because of that. You think that there is no power supply, but actually the neutral wire is taking current towards you. You carelessly try to repair the fuse, and you get a shock.
Thus, neutral wires are not preferred in fuse.
What else can I help you with?
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.
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.
Can ammeter be connected in neutral wire?
No, an ammeter should not be connected in the neutral wire of a circuit. It should be connected in series with the load on the live wire to measure current flowing through the circuit accurately. Disconnect the power source before connecting an ammeter and always follow safety guidelines when working with electrical circuits.
Why fuse inserted in phase wire only?
The fuse is place in the live wire so that under fault conditions the supply is cut off but the equipment is still connected to the neutral wire. If both wires were fused, there would be a 50-50 chance of the one in the neutral going first, which could leave the equipment still connected to the live wire and thus a further potential danger.
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.
How the fuse connected ina domestic current?
The fuse is connected in series - usually in the live connection.
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.
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!
Why is the fuse connected to the live wire?
because current flows through live wire
A fuse should be conected between?
A fuse should be connected in the live wire, before reaching the appliance.
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.
Why fuse is not connected in neutral wire?
Because the neutral wire only carries unbalanced currents. The hot wire carries full load currents. Answer for European SystemsThe above answer is only true for three-phase systems. In single-phase systems, the neutral carries exactly the same current as the line conductor. The reason for not placing the fuse in the neutral conductor is one of safety. For example, if the fuse were to blow due to, say, an overload current, then although no current could flow, the entire conductor would remain live and highly dangerous.
Can ammeter be connected in neutral wire?
No, an ammeter should not be connected in the neutral wire of a circuit. It should be connected in series with the load on the live wire to measure current flowing through the circuit accurately. Disconnect the power source before connecting an ammeter and always follow safety guidelines when working with electrical circuits.
Does a toaster use a neutral phase?
There is no such thing as a 'neutral phase'. 'Live' or 'hot' conductors are called 'lines', whereas the neutralconductor is at approximately earth (ground) potential.So, a toaster would be connected between a line and a neutral conductor.
Why should you not connect any electrical switch to the neutral instead of the phase?
IF Neutral is connected to the Switch then Live still exists on the socket even if the Switch is OFF.In such a situation a person can get a shock as Live can form a circuit thru the body to Ground.
Why fuse inserted in phase wire only?
The fuse is place in the live wire so that under fault conditions the supply is cut off but the equipment is still connected to the neutral wire. If both wires were fused, there would be a 50-50 chance of the one in the neutral going first, which could leave the equipment still connected to the live wire and thus a further potential danger.
Why should a polarity test be conducted out on a lighting circuit?
to make sure the protection device such as fuse are connected at the live part
