Where does the neutral wire go on a transformer?

Commonly the system neutral is connected to the star point on the feeding transformer. This is the reason that the secondary side of most three-phase distribution transformers is wye- or star-wound. Three-phase transformers and their associated neutrals are usually found in industrial distribution environments.

Why is fuse connected to live wire and not neutral?

Once the fuse has melted, the circuit is broken and no more current flows through the device. The fuse or circuit breaker must be connected in the live wire side of a domestic circuit to ensure that it keeps high voltage from reaching the user, or surroundings, if a fault develops.

What is the purpose of neutral wire in transformer?

“The neutral wire serves as a return path for electrical current while the ground wire provides a path for electrical current to earth. Since electricity flows from source to destination and back, each wire serves a specific need to ensure the loop is maintained.”

Why is neutral connected to earth in a transformer?

Solidly earthed systems Neutral earthing resistors are used to limit the fault current in transformers When a phase to earth occurs, the fault current is limited only by the soil resistance. This current, which can be very high, can damage the windings.

What happens when live wire touches neutral wire?

Answer: 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.

What will happen if fuse is connected to neutral wire?

The fuse wire is always connected in the live wire of the electric circuit because if the fuse is somehow put in the neutral wire in the circuit, then due to excessive flow of electric current when the fuse burns, current will stop flowing in the circuit, but the appliance will still remain connected to the high …

Where does the neutral wire go on a transformer? 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. Click to see full answer.

What is a neutral in electrical wiring?

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.

Do I need a second transformer for a neutral load?

The size of that second transformer only need be based on the neutral load you are trying to supply and not necessarily sized to match the source transformer. This may not be the ideal permanent install, but can come in handy as a temporary thing, say you lost underground neutral or something like that.

Can a transformer be connected parallel to another Transformer?

Another transformer parallel to the first effectively is an autotransformer, but may be more stable voltage then connecting to a center tap of a resistive load. The size of that second transformer only need be based on the neutral load you are trying to supply and not necessarily sized to match the source transformer.
