Beginning of the story was here - Is RC2040M150CH MSP upgradable to 200amps main circuit breaker
So now I got QOM2200VH main circuit breaker (200amps) and ready to install it later this week.
The only question I have is Neutral.
Notice that the current service breaker (QOM2150VH) has a bar which reads "N" on it :
The new one doesn't have this part (there is no plastic bar which reads "N" on it):
This a little worries me. Unfortunately I can't disconnect and check in details until the scheduled time with my electric service company to make the disconnect later this week.
Both circuit breakers are two-phase circuit breakers. But the existing circuit breaker supposedly has a connection to Neutral!? And the new circuit breaker doesn't have it!?
Thanks for any leads on this topic.
