Product FAQs
7 answersWhat is the difference between GE THQP and THQL circuit breakers?
THQP breakers like the THQP140 are half-inch wide thin breakers designed to maximize panel space. THQL breakers are standard one-inch wide breakers. THQP breakers can only be installed in panel slots specifically designed with specialized bus stabs to accept them.
Will the THQP140 fit in all GE load centers?
No. The THQP140 only fits in GE PowerMark Gold and PowerMark Plus load centers that are configured for half-inch THQP breakers. Always verify your specific panel label to confirm it accepts the THQP frame type before installation.
What wire gauge is compatible with the THQP140 breaker?
The box lug terminals on the THQP140 accept 8 AWG to 4 AWG copper or aluminum wiring.
Can the THQP140 replace older TQP series breakers?
Yes, the THQP140 is a direct replacement for the discontinued TQP140 circuit breaker. It provides a seamless fit for older GE panels requiring a 40A single pole breaker.
Is the THQP140 suitable for HVAC equipment?
Yes, the THQP140 is HACR rated. This makes it suitable for heating, air conditioning, and refrigeration applications that require a 40A circuit breaker.
How does the THQP140 mount into the electrical panel?
The THQP140 uses a plug-in connection. It snaps directly onto the bus bar of compatible GE load centers without the need for bolted connections.
What type of trip technology does the THQP140 feature?
This breaker uses a fixed thermal magnetic trip unit. It includes long-time and instantaneous trip functions to protect circuits from overloads and short circuits.
