Some quad breakers are labeled "common" trip. This means that they have an internal common trip mechanism in addition to the visible handle tie.
I see how this works for the 240 v. breaker in the middle.
But does this apply to the outer set also? Do they have some kind of connection that tunnels thru the middle breaker? In other words, if the visible outer handle tie is broken or removed, do those outer breakers trip together?
Some quad breakers are labeled "independent". This means that the middle 240 v. is internal common trip and the outer breakers are standard independent breakers with a handle tie only on the middle set.
Do they just manufacture one quad breaker (the independent type) then label it common trip because they have added the C shaped outer handle tie? In other words, if you remove the outer handle tie....do you now have the equivalent of the independent type ?
I have read manufacturer descriptions and cannot find an answer anywhere.
Now, the tougher question....Can an inspector require that each 120 v. circuit be fed from a separate circuit breaker? That is, prohibit using a 240 v. breaker to power two unrelated distinct separate 120 v. circuits? I understand how this would make trouble shooting easier. Is the NEC silent on this issue?
