Product FAQs
7 answersWhat load centers are compatible with the THQLQ154015 quad breaker?
This breaker is designed for use in ABB ReliaHome, GE PowerMark Gold, and GE PowerMark Plus load centers. It fits standard 1-inch spaces and does not require special half-inch wing stabs.
Is the ABB THQLQ154015 the same as the GE THQLQ154015?
Yes. Following ABB acquiring GE Industrial Solutions, the THQLQ154015 is the exact same product, manufactured to the same specifications but updated with ABB branding.
How much panel space does the THQLQ154015 require?
This quadplex breaker requires two standard 1-inch spaces to provide four circuits, allowing you to add a 40A two-pole load while maintaining two 15A single-pole branch circuits in a compact footprint.
What wire sizes do the outer and inner poles accept?
The outer 15A poles accept 14-8 AWG copper or 12-8 AWG aluminum wire. The inner 40A poles accept 8-4 AWG copper wire.
Do I need special rejection clips or wing stabs to install this quad breaker?
No. Unlike GE THQP half-inch breakers, the THQLQ series fits into standard full-size mounting positions without requiring special wing stabs.
How are the circuits configured internally on this quad breaker?
The outer positions function as two independent 15A single-pole circuits, while the inner positions operate as a single 40A two-pole circuit with a common trip mechanism.
What type of trip mechanism does this breaker use?
It features a fixed thermal-magnetic trip unit with long-time and instantaneous (LI) trip functions to protect against overloads and short circuits.
