Even more fun, when you have a 400amp breaker blow, causing the other phase to blow out that side. Nice fourth of July action.
Obviously a failed breaker could allow ZERO volts to be realized. I mistakenly interpreted your comment to mean that a faulty breaker could allow a partial voltage to be realized. Say, 50 volts for example.

I just replace big 1600 amp breaker for my industrail customer it was no fun with that one it did knock the POCO transfomer out of commison end up replace that as well. ( BTW it is 415Y240 volt system )

I have see some three pole breaker go bad on one " phase " ditto with common 2 pole breakers.

Merci,
Marc

If you did get 50 volts going thru the breaker like example then you have something is burning inside the breaker useally the concat is bad or pitted up pretty serious. For sure you can hear the cracking sound ( I can pick up the viberations so I know it is cooking pretty hard )

Sometime you can get the larger two pole breaker like main breakers it can do show up in funny way depending on what model it is.

Merci,
Marc
