When a phase line touches the neutral by any conducting material means the Short Circuit. If there is a short circuit then the current in that circuit will be much higher and this increase in current may damage the the devices that are connected to that line.

Two phase-wires or lines of a three-phase supply provide a single-phase supply with a voltage 73% more than the line-to-neutral voltage. With a 240 v house supply as used in the UK for example, the 240 v is between one line and neutral, and the voltage between lines is 415 v. Connecting this will cause the bulb to be unusually bright but it would last only a short time.

If the "hot" wire comes into contact with the neutral wire it will cause, what is known in the trade, as a short circuit. A high capacity of current will be drawn and the protective circuit breaker will trip.

With luck it will blow the fuse and cut off the power . . . if that does not happen there is a possibility of a fire.

How can you lay earthing strip on cable tray?

no use laying an earthing strip in a cable tray better tap both the ends of the earthing wire to the trunking,it will save your wire also,or lay out a cable in the other trunking where you have low voltage wire running in.


What is the difference between earthing boss and earthing lug and where to use?

An earthing boss and earthing lug are parts of a grounding connection. An earthing boss is in a casting that allows for the drilling and tapping of hole. A earthing lug is used to bond a wire to the ground.

Why does an thick earthing wire?

A thick earthing wire, or a wide, flat conductor, is preferred, because it's more important to minimize henrys (inductance) in the earthing system than to reduce ohms (resistance). For the same reason, corners and small angles in an earthing conductor should be avoided, and the conductor should approach any connections from a parallel direction.


What happens if neutral and hot touch each other?

If a "hot" wire contacts the "neutral" or ground wire, electrical current flows to the ground.
