Product FAQs
6 answersWhich load centers accept the THQLQ201520 quad breaker?
It is engineered for ABB ReliaHome, GE PowerMark Gold, and GE PowerMark Plus load centers. The plug-on design is compatible with both new and legacy single-phase panels, fitting securely whether the panel has wing stabs or not.
How many panel spaces does the THQLQ201520 require?
This quadplex breaker requires two standard 1-inch spaces. It allows you to add two 20A 1-pole circuits and one 15A 2-pole circuit into a fully populated enclosure without needing a subpanel.
How are the 15A and 20A circuits configured on this quad breaker?
The breaker provides two independent 20A single-pole circuits on the outer connections and one 15A double-pole circuit on the inner connections. The center 15A poles share a common trip mechanism for 240V loads.
Can I use the ABB THQLQ201520 to replace a GE THQLQ201520?
Yes. ABB acquired GE Industrial Solutions, so Q-Line breakers are now manufactured under the ABB brand. The THQLQ201520 is an exact drop-in replacement for the legacy GE version, maintaining identical form, fit, and UL listings.
Is the THQLQ201520 suitable for HVAC equipment?
Yes, this breaker is HACR rated, making it suitable for heating, air conditioning, and refrigeration motor loads. It also carries an SWD rating for switching duty applications.
Can I install this quad breaker in any slot within a PowerMark load center?
You must verify that your specific load center is listed to accept tandem or quadplex breakers. Check the panel wiring diagram for slots designated for half-inch or quad breakers, as installing them in restricted slots violates electrical code.
