Assignment Help:

Why earthing is required for any electrical equipments, domestic installation and service building etc? For TL coaches what is the minimum I.R. value needed for new wiring?

Ans: To drain away any leakage of currents due to poor insulation and to save human life from dangerous shock and also to avoid burnt of electrical equipment.

The minimum IR value needed for wiring is 2M?'s and minimum IR value required in service for giving coach fit for service is 1M?.
