GE TQD22100 2-Pole 100 Amp Circuit Breaker

The TQD series uses a bolt-on mounting design, which means it physically fastens to the bus bar with screws rather than snapping on. Verify your panel accepts bolt-on breakers and is compatible with the GE TQ series before ordering — not all GE panels take bolt-on breakers interchangeably with plug-in types.

A 2-pole 100A/240V breaker is most commonly used as a main breaker in a subpanel, as a disconnect for large HVAC equipment, electric ranges, EV charger circuits, hot tubs, or as a feeder breaker in an existing panel for a downstream distribution point. The two poles bridge both legs of a 240V split-phase service simultaneously.

10kAIC (kiloampere interrupting capacity) means the breaker is rated to safely interrupt a 10,000-ampere fault current without failing catastrophically. Most residential panel fault currents fall between 10kA and 22kA depending on utility transformer proximity — verify the available fault current at your panel's location against the NEC and local code requirements before specifying this breaker.

This breaker is sized for high-demand 240V branch circuits: sub-panels, electric ranges, dryers, large HVAC equipment, EV chargers, and workshop circuits feeding heavy tools. The two poles each carry 120V; combined they deliver 240V across the load.

10KAIC (10,000 Amperes Interrupting Capacity) means this breaker is rated to safely interrupt fault currents up to 10,000 amps without failing catastrophically. For most residential and light commercial panels, available fault current is well below 10kA, making this rating appropriate. In industrial settings with high available fault current, verify your panel's fault current level against this rating.

The TQD series is designed for GE and compatible load centers. "TQ" series breakers fit GE TQL-series and many compatible panels. Confirm your load center's approved breaker list before installation — using a non-listed breaker in a panel is a code violation regardless of physical fit.

The "D" in TQD denotes a distinction in the breaker's design or feature set within GE's TQ series — this may indicate a specific mounting configuration or rating variant. Verify the TQD22100 is the correct part number for your load center and application against GE's compatibility documentation.

The TQD22100 uses a thermal-magnetic trip mechanism. Thermal elements respond to sustained overload conditions (heat buildup over time), while magnetic elements trip instantaneously on short-circuit current spikes. The combination protects both against slow overloads and sudden faults — standard practice for a molded case breaker in this class.

It works in both scenarios, provided the panel is rated for the GE TQD bolt-on series. As a replacement, match the amperage, poles, voltage, and mounting type to the existing breaker. For new installations, confirm the panel's breaker compatibility list.

Panel work involving main breakers and high-amperage circuits requires working inside an energized panel. In most jurisdictions, this work requires a licensed electrician and an electrical permit. Even in jurisdictions where homeowners can perform their own electrical work, a licensed inspector must verify the installation. This is not a DIY task without proper training and lockout/tagout procedure.
