BR420looking to swap out the (2) BR220's in there for a quad, BQC220220, BRDC220220 or the like.
Seems like quads exist that have the rejection feature, or common trip, but not both.
I think all dp breakers are common trip but 2 sp breakers with handle ties are not common trip and you would use that on a multiwire branch circuit.This one specs as "independent trip." I believe "common trip" is required, no?
In fact, I wonder when you'd EVER want a double-pole breaker that wasn't "common trip."
That would be 2- dp breakers taking up 2 spaces. Is that correct? If so then I believe those are factory built for common tripSo the units like BR420 with built-in handle ties but independent trip are for mwbc's.
My application here is for a quad for (2) 2-pole circuits, 240-volt loads.
Bryant 20/20 Amp Quad Double Pole Twin Circuit Breaker BQ220220
The quad type circuit breaker is designed to create 4 circuits in 2 spaces. This allows for two 240 volt circuits.
This circuit breaker is compact and easy to install. Two pole circuit breaker features thermal magnetic molded case for extra protection. Circuit breaker has a current rating of 20/20 amps. It is a 2″ thick quadplex independent trip breaker.
Wire size: 14/4 AWG. Breaker is 2″ thick
