Product FAQs
8 answersWhat load centers are compatible with the BQ220220 circuit breaker?
This breaker is designed for use in Eaton BR series load centers. It is also a direct, UL-listed replacement for legacy Bryant, Westinghouse, and Challenger panels that accept Type BR breakers.
How much panel space does the BQ220220 require?
As a quadplex breaker, it provides two separate 20A, two-pole circuits while only occupying two standard 1-inch spaces in the panel. This allows you to add 240V capacity without requiring a subpanel.
What does independent trip mean on this quadplex breaker?
It means the breaker contains two separate two-pole circuits (the inner poles and the outer poles) that operate independently of each other. A fault on the inner 20A circuit will not automatically trip the outer 20A circuit.
Can I use the BQ220220 to power 240V appliances?
Yes, this quadplex breaker provides two independent 120/240V, two-pole circuits. It can be used to supply power to two separate 240V loads up to 20 amps each, such as dedicated appliance circuits or HVAC equipment.
Does this breaker provide AFCI or GFCI protection?
No, the BQ220220 is a standard thermal-magnetic circuit breaker. It provides essential overload and short-circuit protection but does not feature Arc Fault (AFCI) or Ground Fault (GFCI) capabilities.
Can I install this breaker in a Square D or Siemens panel?
No, the BQ220220 is strictly for use in Eaton BR, Bryant, Westinghouse, and Challenger load centers. It is not listed or designed for use in Square D, Siemens, or GE panels.
Is the BQ220220 a direct replacement for older Westinghouse quad breakers?
Yes, Eaton acquired the Westinghouse and Bryant load center lines. The Eaton BR series, including the BQ220220, is the official, UL-listed replacement for these legacy panels.
Is the BQ220220 rated for both copper and aluminum conductors?
Yes, the box lugs are rated for both copper (Cu) and aluminum (Al) wiring. When terminating aluminum conductors, it is recommended to apply a suitable joint compound or oxide inhibitor to prevent corrosion.
