Product FAQs
5 answersCan I use the THHQL2190 to replace a standard THQL2190 breaker?
Yes. The THHQL2190 has a 22kAIC interrupting rating, which exceeds the 10kAIC rating of the standard THQL2190. It shares the same 1-inch per pole physical dimensions and fits the same GE PowerMark Gold and ABB ReliaHome load centers, making it a safe and compliant upgrade.
What does the "HH" in the THHQL2190 part number indicate?
The "HH" designates this as a high-interrupting capacity breaker rated at 22kAIC at 120/240VAC. Standard GE Q-Line breakers (THQL) are rated at 10kAIC.
What are the lug torque specifications for the THHQL2190?
The required torque depends on the wire size used. For 6 AWG to 4 AWG wire, torque the lugs to 45 in-lbs. For 3 AWG to 1/0 AWG wire, torque the lugs to 50 in-lbs.
Is the THHQL2190 interchangeable with THQP thin breakers?
No. The THHQL2190 is a full-size breaker that requires 1 inch of space per pole, totaling 2 inches for this 2-pole model. THQP breakers are half-inch space-saving models and mount differently to the panel bus.
Does the THHQL2190 include an internal common trip?
Yes. As a 2-pole breaker, it features an internal common trip mechanism that ensures both poles disconnect simultaneously during an overload or short circuit, preventing single-phasing on 240V circuits.
