Frequently Asked Questions
What electrical panels is the GE THQB32100 compatible with?
This is a bolt-on type breaker designed for GE panels that accept THQB-series breakers. It is not interchangeable with plug-in (THQ) or other manufacturer's panels. Verify your panel's bus bar accepts bolt-on mounting before purchasing.
Can I use this breaker as a main breaker or is it only for branch circuits?
The THQB32100 at 100 amps and 3 poles can serve as a main breaker in a sub-panel or as a branch circuit breaker feeding large 3-phase loads like HVAC equipment, welders, or commercial machinery. Your panel's bus bar rating must be equal to or greater than 100 amps.
What wire size do I need for a 100-amp 3-pole breaker?
Per NEC code, 100-amp circuits typically require #1 AWG copper or 1/0 AWG aluminum conductors, though you should verify with your local electrical code and the specific wire's ampacity rating for your installation conditions.
Is this breaker rated for 120/240V single-phase or 3-phase applications?
The THQB32100 is a 3-pole 240V breaker suitable for both 3-phase commercial applications and single-phase 120/240V panels where a 3-pole configuration is required. The three poles allow it to protect all three legs of a circuit simultaneously.
Does this breaker have a 10,000 AIC interrupting rating?
GE THQB-series miniature circuit breakers carry a standard 10,000 AIC (Ampere Interrupting Capacity) rating, which is suitable for most residential and light commercial installations. Verify your panel's available fault current does not exceed this rating.
