Product FAQs
6 answersCan I install the TQC1140 in a standard GE residential load center?
No. The TQC1140 is a unit-mount circuit breaker designed for individual enclosures and control panels. It does not plug into the busbars of standard GE residential load centers, which typically require THQL or THQP plug-in breakers.
How is the GE TQC1140 mounted?
This breaker features a unit-mount design. It is typically secured to a backplate or mounting base, such as the TQCBMPA1 screw-type plate, inside a control panel or individual enclosure rather than snapping onto a panelboard bus.
What type of wire connections does this breaker use?
The TQC1140 is a feed-thru breaker equipped with box lugs. This allows for direct wire connections without needing a busbar. It accepts 8-3 AWG copper or aluminum wire.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the breaker uses a thermal-magnetic trip unit providing Long-Time (L) overload protection and Instantaneous (I) short-circuit protection. Both settings are fixed on this 40A model.
Are GE TQC1140 and THQC1140 breakers interchangeable?
Yes. In GE nomenclature, the TQC and THQC prefixes for this frame size both represent 1-inch wide, unit-mount (cable-in/cable-out) breakers. They are functionally identical and often listed together as direct replacements.
Does the TQC1140 provide arc-fault (AFCI) or ground-fault (GFCI) protection?
No. The TQC1140 is a standard thermal-magnetic circuit breaker. It provides protection against overloads and short circuits but does not include built-in AFCI or GFCI circuitry.
