Why is it dangerous to touch the live wire of main supply?

Why is it dangerous to touch the live wire of main supply?

(a) It is more dangerous to touch the live wire of a mains supply rather than the neutral wire because the live wire has a high potential of 220V, whereas neutral wire has zero potential as it is grounded at the power station; therefore, it is not dangerous to touch the neutral wire.

What happens when a live wire and neutral wire touch?

The path from the live to the neutral wire has very low resistance and will create a short circuit if the large current exceeds the fuse rating. There will be a blow.

Is it safe to touch the neutral wire?

5 Answers. The neutral is NOT safe to touch. When everything is working correctly, it should be at most a few volts from ground. This is why modern appliances either have two prongs and everything is insulated from the user, or three prongs and anything conductive the user can touch is connected to ground.

Why is it not dangerous to touch a neutral wire?

Literally. Neutral wire has a V same as ground i.e almost 0. In a perfect world, with perfect zero-impedance electrical conductors everywhere, there is no voltage between neutral and ground. In that perfect world, you could safely touch the neutral wire.

What precautions are necessary while handling electrical appliances?

1- Always use insulated tools while working.

  • 2-Never use equipment with frayed cords, damaged insulation or broken plugs.
  • 3-Know the wire code of your country.
  • 4-Never use an aluminium or steel ladder if you are working on any receptacle at height in your home.
  • 5-Avoid water at all times when working with electricity.

When was insulated wire invented?

An insulating material that encases electrical cables or other equipment is insulation. The first electrical systems to make use of insulators were telegraph lines. This took place in the 1840’s.

What happens when live wire touches ground?

If you touch it, you may complete a circuit between the live wire and the earth (because you’ll be standing on the floor), so you get a shock. The flow of charge (current) in a circuit can travel in one direction around the circuit only. This is due to a direct supply of potential difference, also known as dc.

What happens when live wire touches earth wire?

If a live wire touches the earth wire, you get a spark and the circuit breakers blow.

Can we touch phase wire?

If we touch the Phase wire without touching Ground, no shock will happen. If we touch the phase while standing from ground, full load transmits in our body and according to Current value, even death can occur.

What is live and neutral wire?

LIVE WIRE The live wire is connected directly to the generators of the electricity supply company.It carries current at high voltages (about 220−230V). NEUTRAL WIRE The neutral wire returns the electricity to the generator after it has passed through the appliance. The neutral wire completes the circuit.

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.

Is touching a neutral wire more dangerous than a live wire?

It is just a myth that touching live wire is more dangerous than neutral wire.This is because Both live as well as neutral wires carry the same amount of Current.Neutral wire just provides a return path to the current by completing the Electrical Circuit.

What happens when you come in contact with a wire?

If you are on on ground and come in touch with the live wire, you get a shock, severity of which depends on your body condition. When you are in contact with live wire of 230V (110V in some countries), a current passes in our body, which interferes with signals in our nerve systems.

What happens when you touch a live wire with your fingers?

ground potential) but the live wire is not at ground potential so when you touch live wire there is a potential difference and current will pass through your body that is called electrical shock. so touch the live wire and you will win a shock , congratulations on your winning.

Can you get a shock if you touch the Live Wire?

Now there is another case when you can get a shock if you touch the live wire and the ground. This is because just before the electricity board in your house the ground wire is connected to the ground beneath your feet. This ground now holds same potential as the neutral wire and you get a shock.
