How do you inspect a NSX100 - 250 plug-in base is still healthy to use

Verification of NSX 100-250 plug-in base working can be performed by performing below mentioned steps. 

1 - With the NSX not installed on the plug-in base, check that you are able to go to the ON and OFF toggle position.  you can also push the "trip" red pushbutton on the NSX front face in order to make the breaker to trip and check if you can reset it (go first to the OFF position and then to the ON position)

2 - With the breaker toggle in the ON position, insert the NSX breaker into the plug-in base.   The safety trip interlock  will trip the breaker. The toggle will go to the TRIP position (the position in the middle between ON and OFF position)

3 - With the breaker already on the plug-in base and with the toggle on the TRIP position, reset the breaker  (go first to the OFF position and then to the ON position)
