Thanks David,
The manufacturers usually say to exercise it twice a year, but there is applications where it is not really feasible due to the process downstream. There is also cases in the industry where the MCCB did not trip when it was required to, altough it was exercised. Also, do you think...
Good morning,
Please share with me your current practices/strategies on Molded Case Cicuit Breaker ownership.
What do you do for PMs? Do you PM those MCCCB or run to failure?
what mitigation plan? (putting a fuse in line with the breaker, etc..)
MCCB are not draw out breakers, they are bolted...
