A fuse is an overcurrent protection device, which protects a circuit by melting in the event of either a sustained overload current, or a short-circuit current. A short-circuit current will occur when a line (not 'phase') conductor makes direct contact with a neutral (or earth) conductor.
What else can I help you with?
What will happen if a phase and neutral test by a mutimeter shows continuity?
If the test shows that there is a continuity between the phase leg and the neutral with no load connected, then that circuit should not be energized. If the circuit was energized then the fuse or breaker protecting that leg will trip the circuit open.
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 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.
Why would you put a fuse on the neutral side of an electrical circuit?
It does not matter what line in (the phase or neutral) is the fuse. In a closed series circuit current in all areas of the circuit is equal. It's best to put the fuses in both wires (phase and neutral) and even better for each individual device in the chain.
In DC motors why you are connecting fuse to positive and negative terminal and in single phase AC motor why you are connecting fuse to phase line and neutral link to neutral line?
in ac supply both positive and negative cycles contain in single phase the fuse only required for supply side but in dc supply positive and negative seperated by two terminals so we provide two fuses.
Why would mileage and parking statuspark drive reverse neutral not show in dashboard.?
The light bulb may be burnt out for the dashboard display. The fuse for the dashboard display may be blown. The fuse can be found in the fuse box.
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.
My 1984 Nissan pickup will not charge the battery. I have replaced the alternator and put in a new battery.?
Check your ignition fuse,its in the fuse box,also,your fusible link could be burnt or melted,its connected to your positive battery cable,if burnt or melted,then its your problem.
What is meant by single phase preventers in transformers?
Here is a scenario: A 3 phase service with a floating neutral has a fuse in each primary connection. And, in the event any of the 3 fuses blow, the remaining two transformers will be connected across two phases in a single phase arrangement. This condition can damage connected equipment; so sensors are often installed in the service to trip the transformer bank -- in the event any of the primary fuses blows.
Why is neutral line needed in home electricity?
The neutral line in home electricity completes the circuit by providing a return path for current to flow back to the electrical source. It helps balance the electrical load and provides a reference point for voltage measurements. Without a neutral line, the circuit would not function properly and could pose safety risks.
Why is the fuse always connected in the beginning of the circuit?
A fuse is an over current protection device, and will operate wherever it is placed in a circuit. However, because it's important that it isolates the faulty circuit from the supply, it MUST be located in the line (NEVER the neutral) conductor at the point where the circuit is connected to the supply.The point is that the circuit will always be energised (and potentially dangerous) up to the point where the fuse is connected, even when the fuse has operated and no current can flow.
How to identify a burnt fuse Honda Accord?
Pull the fuse out and look at it. If you cannot tell by looking if it is burnt or not, then check the continuity with an ohm meter.
