2 5178Can earth resistance be measured without connecting the earth electrode? and should earthing connections be disconnected What is the effect of connecting two cables of different sizes in parallel with supply? Thanks in Advance. I am intrested to get in touch with some tecnocrats/engineers,my mail i.d is : hiremathvijay@rediffmail.com

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?
