my 10 hp submersible pump is tripping when connected through ELCB.I have checked the megger value of the coil's with body.It was found to be 0.2mega ohm.that is leakage is there.But when connected to mccb it is not tripping.no leakage current in the motor.Is it safe to connect to mccb? what are the problem's will arise if future?also tell me in ELCB no neutral is connected to motor.than how ELCB was working?

following are the questions asked in interviews: 1) Considering the short circuit fault, which switchgear is preferable, SFU OR MCCB? Which operates faster? whicg one is popular in Indian Market and why? 2)Define SCPD. What is type2 coodination? 3)Why the contactor rating is higher for the fuseless selection than for fuse selection? whether the ratinf of SFU or MCCB remains the same in both the cases? 4)If the HP rating is known then can you calculate the ratings of L.V Switchgear(SFU/MCCB, contactor, OLR) without using the selection chart?
