Earth cable used in earth system and Unearth cable used in unearth system. Unearth cable insulation thickness more than earth cable since unearth cable used in high voltage stress side. Basic difference between earth and unearth cable is thickness of insulation and voltage between earth and phase is equal.

Can u explain : how capacitor act when the supply is given is a.c and d.c. I know that when d.c supply is given then the capacitor charges and becomes open circuited. But please say about when a.c is given. I have seen that when a.c supply is given ,it charges and discharges, But when we plug in capacitor to our daily supply and take it out ,then we join those wires spark will appear,which seems charge is present ,but when a.c is given it should charge and discharge
