what is the different between Switch & Circuit Breaker?
Answer Posted / hammad khan (uwa)
Circuit Breaker have the switching capability of switching on and off any kind of currents that is the load current and short circuit currents and can be operated under load conditions.
Whereas a Disconnection switch can only be operated under no load conditions. Currents of Busbar without load and also no load currents of transformer with low rating can be switched on and off. So interlocking with circuit breaker is necessary.

How do i perform grounding of star point of Genset (400V) for making connection with step up transformer of DELTA-DELTA (400V to 20KV) ? while Genset itself has its own neutral and grounding bus bar inside genset breaker box whereas we have another neutral and grounding busbar in synchronizing panel next to genset at maximum distance of 6meter, would someone pls advice if we can only perform neutral grounding in synchronizing panel or should we ground neutral on both places inside genset breaker box and synchronizing panel.

In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.
