For Masterpact Breakers, what is the difference in Charged OK versus Charged Not OK?
Masterpact Circuit Breakers
For Masterpact NT and NW Circuit Breakers, when the closing spring is completely charged, there is a status indicator (flag) that to show whether the breaker can now be closed.
If there is nothing to interfere with the closing process, then the flag will show "Charged OK".
If there is something that will interfere with the closing process, then the flag will show "Charge Not OK".
See the picture below to compare the difference in the flags, along with some reasons for Charged Not OK.
