Description
Built to maximize wiring capacity, this quadplex breaker consolidates four 15A circuits into a standard two-pole space. Inner poles feature a common trip mechanism for 240V applications, while outer poles operate independently for 120V loads. Designed to snap into GE PowerMark Gold load centers, this non-CTL unit is ideal for expanding older residential services. It functions as a cross-reference for the newer THQLQ151515 model. This 10kAIC thermal-magnetic breaker is HACR and SWD rated.Specifications

Product FAQs
6 answersWhich panels are approved for use with the TR21515 quadplex breaker?
It is designed specifically for GE Load Centers and PowerMark Gold Load Centers. Verify that your specific panel wiring diagram allows for quadplex or tandem breakers in the intended slot, as some older panels restrict multi-pole breakers to specific spaces.
How does the quadplex configuration of the TR21515 save panel space?
The quadplex design consolidates four independent 15-amp poles into a single breaker assembly. This allows you to add multiple circuits to a GE Q-Line load center without requiring four full-size breaker spaces.
Can I use aluminum conductors with the TR21515?
Yes, the box lug terminals are dual-rated for both copper and aluminum wire. Ensure you use 12 to 8 AWG for aluminum conductors, or 14 to 8 AWG for copper, and apply an approved oxide inhibitor when terminating aluminum.
Does the TR21515 require mounting hardware?
No mounting hardware is required. It utilizes a plug-on connection that snaps directly onto the busbar of compatible GE and PowerMark Gold load centers.
What does the 10kAIC rating indicate for this breaker?
The 10kAIC rating means the breaker can safely interrupt a maximum fault current of 10,000 amps at 240V AC. This is standard for most residential and light commercial GE load centers.
How does the thermal-magnetic trip mechanism operate on the TR21515?
The breaker utilizes a fixed LI (Long-Time, Instantaneous) trip curve. The thermal element provides long-time protection against sustained overloads, while the magnetic element provides instantaneous tripping to clear short circuits safely.
