Hi all,
I would like to clarify on the ratings of a Circuit breaker ratings given that the FLA ratings are known.
We are currently in the process of a having a vendor design 4 vacuum pumps but the schematics are showing Circuit breaker rating and FLA ratings of the motors to be the same
In my past experience, inspectors have asked to ensure the C.B was rated for 175% of the FLA but I believe it can be minimum 125% and maximum 175%
Please advise, if I advise the manufacturer to choose the CB such that it is between 125%-175%, will it be acceptable?
Thank you,
