Meet the GE THQB1120GF 20A 1P 120V GFCI Bolt-On circuit breaker — a reliable safeguard for panelboards, load centers, and electrical distribution. Built for retrofit work, this unit keeps your service consistent by preserving the part number you need for ongoing maintenance and procurement.

What makes THQB1120GF stand out

  • GFCI protection on a 1-pole, 120V circuit with a 20-amp rating — providing fast interruption on ground faults to protect people and equipment.
  • Bolt-On mounting design for straightforward replacement in compatible GE panelboards and load centers, minimizing service interruptions and panel modifications.
  • Part-number continuity helps maintenance planning, stocking, and retrofits where a specific GE component is required.
  • GE engineering compatibility: designed to fit GE distribution systems that accept THQB-type breakers, ensuring reliable performance with established gear.
  • Available from AmpState, with support to confirm fit if you're matching a part number against your existing gear.

Practical applications and installation tips

Use this 20A, 120V GFCI breaker on circuits running in areas where moisture or water exposure is possible, such as kitchens, baths, basements, or garages, to meet ground-fault protection requirements. The bolt-on style enables a fast, sturdy installation into compatible GE panels, while the 1-pole configuration keeps your panel organized and straightforward.

Before installing, verify that your panel accepts THQB-series, bolt-on breakers and that the existing circuit matches a single-pole, 20A, 120V configuration. If you’re unsure about compatibility, AmpState offers guidance to confirm fit and ensure a safe, code-compliant replacement.

Why choose this for your next project

For contractors and homeowners working on retrofit projects or routine maintenance, the THQB1120GF delivers reliable ground-fault protection without changing your panel architecture. It pairs GE’s trusted engineering with a practical, retrofit-friendly form factor, helping you minimize downtime and keep electrical distribution running smoothly.
