how to check the earth resistance value& what is the
minimum earth resistance for good earthing sysytem.
Answer Posted / tauseef tarique, engineer(e)
The earth resistance value can be checked by the use of
earth resistance tester (called megger earth tester). The
best earth resistance should be less than one ohm but the
permissible value is less than 5 ohm. For rocky areas it
should be less than 8 ohms.

I have an existing old MCCB. ABB Model SACE, the rating are: Ue = 660 volts, Iu =1250 Amps, 3 poles, Ith (max) =800 amps at 45 deg C. I need a circuit breaker for my 3 phase motors, 380 volts 60 hz. the supplier required the minimum ampacity of the breaker to be 911 amps. can i use this breaker with rating of Iu =1250 amps but Ith = 800amps maximum?
