Product FAQs
7 answersWhat panels are compatible with the BQ2302120 quadplex breaker?
This breaker is designed for use in Eaton, Cutler-Hammer, and legacy Bryant Type BR load centers that accept CTL (Circuit Total Limitation) breakers. It requires notched bus stabs to accommodate its rejection tab.
How are the 20A and 30A circuits configured on this quadplex breaker?
The BQ2302120 provides two independent single-pole 20A circuits on the outer poles and one two-pole 30A circuit on the inner poles.
Why does the BQ2302120 have a rejection tab?
The rejection tab classifies this as a CTL (Circuit Total Limitation) breaker. It prevents the breaker from being installed in non-notched panel slots, ensuring the panel does not exceed its maximum designed number of circuits.
Will this breaker fit in older Westinghouse or Bryant panels?
Yes, Eaton Type BR breakers are backward compatible with legacy Cutler-Hammer, Westinghouse, and Bryant BR-style load centers, as long as the specific slot has a notched bus stab to accept the CTL rejection tab.
Can this breaker be used for HVAC equipment?
Yes, the BQ2302120 is fully HACR rated, making it suitable for heating, air conditioning, and refrigeration motor loads that require a 20A or 30A circuit.
What wire material is compatible with the BQ2302120 box lugs?
The box lugs on this breaker are rated to accept both copper (Cu) and aluminum (Al) wiring ranging from 14 AWG to 4 AWG.
Are the 20A poles on this breaker switch duty rated?
Yes, the 20A single-pole circuits on the BQ2302120 are SWD (Switch Duty) rated, allowing them to be used for switching 120V fluorescent lighting loads on and off regularly.
