Earthing is connecting non-current carrying parts of equipments to ground in order to avoid electric shocks.It may be also used for protection by measuring leakage current

While Neutral is connecting R ,Y ,B Phase to common point with ground it is called system earthing

As we use capacitior bank in 3ph ckt for improvement of PF, why not we use capacitor in single phase domestric use, at our house their are many inductive equipments,like fan,mixer,tube choke,air conditioner they also draw PF... by using capacitor can they improve PF. if yes--what are advantage and how to connect a capactor in single ph,and which type of capacitor if no- what are disadvantages.
