What happens if the live wire touches the neutral wire?
The live wire touches the neutral wire.
– This will create a short circuit as a large current which exceeds the fuse rating will from the live (240 V) to the neutral wire (0V) as that path has very low resistance.
The fuse will blow.
The live wire touches the earth wire..
Can you connect two neutral wires together?
You can have two circuits share the same neutral wire even but they have to be on opposite phases. If they are on opposite phases then the current carried by the neutral will only be the differential between the two circuits and will never exceed the breakers limit.
What is the point of a neutral wire?
Neutral is a circuit conductor that normally completes the circuit back to the source. Neutral is usually connected to ground (earth) at the main electrical panel, street drop, or meter, and also at the final step-down transformer of the supply.
Why did I get shocked on the neutral wire?
When you have power going to any part of your house, if there is any type of load on it,and you take the neutrals apart,you are interrupting the load so if you touch the 2 neutrals at any time you can become the neutral which is how and why you feel the shock. It can be harmful depending on the load.
Can a light work without neutral?
Can a light work without a neutral? Sure, but if you have no neutral you have to have something else to return lightbulb current to. … Then, you need two light bulbs to handle the voltage and you need to wire them in series. If you do that they should work just fine.
Can I use neutral as ground?
a ground and a neutral are both wires. unless they’re tied together with other circuits, and not a ‘home run’ back to the panel, there is no difference between the two where they both end up on the same bus bar in the box.
What happens if you switch neutral and ground?
If you swap the two, then you have normal circuit current flowing on the ground wire and potential ground fault current flowing on the neutral wire. … So, to prevent this, the National Electrical Code prohibits the connection of the equipment ground and neutral at any point other than the service.
Can I connect all neutral wires together?
Neutrals, like grounds, can all get tied together, but it is best if they are all part of the same circuit (I.e. If your turn off the circuit breaker there is nothing powered in that box). Wire nuts have a rating for how many wires you can safely tie together.
Why is there no voltage on neutral?
The difference in voltage between neutral and ground should be due only to the voltage drop in the neutral due to the current flowing in it — ideally there will be no current flowing in the ground wire and so no voltage drop in the ground wire unless a fault exists in the electrical system.
Can a white neutral wire shock you?
No. By definition a neutral wire is a wire that is grounded to 0V. It does carry the current from the circuit back to the transformer however. If a system is wired correctly the neutral wire will never give you a shock.
How can a neutral wire shock you?
As you see in the above diagram the person got an electrical shock because there is a fault in the neutral wire. In this case, the person touches the neutral wire but as the neutral is faulted, the current flowing through the load and the body of the person to the ground.
Is there any voltage in neutral wire?
In the electric power grid, “neutral” is ground, by definition. So the voltage of the neutral wire is always zero… … If you measure the voltage between two different points on a neutral wire that is carrying current, you will be able to measure a small difference.
Can two lights share a neutral?
1 Answer. If they are all on the same circuit, yes. … If one circuit breaker turns off all three lights, then they are on the same circuit and you should be good to go.
What will happen if fuse is connected to neutral wire?
The current flows in excess, but the circuit doesn’t disconnect. The same may happen if the fuse is connected to neutral. Because the fuse can disconnect the circuit only when the excess current flows completely through the neutral. … As far as the current is not returning to the neutral, the current continues its flow.
Does a timer switch need a neutral?
Many electrical timers require a neutral so that the switch can be powered without sending power to the load. … A traditional switch only switches the live so it does not need the neutral. If there is no neutral then unfortunately, youneed to keep reading.
