Product FAQs
5 answersWhat equipment is the TMQC22100MM designed to be installed in?
This breaker is specifically designed to function as a tenant main breaker in GE Meter Mod III modular metering stacks.
What does the MM suffix in the TMQC22100MM catalog number indicate?
The MM suffix indicates that the breaker includes the required mounting hardware kit for installation into 125-amp or 200-amp single-phase residential meter sockets within the Meter Mod III system.
Are there higher-rated alternatives or direct replacements for the TMQC22100MM?
Yes. If a higher short-circuit interrupting rating is required, the TMQF22100MM (65 kAIC) or TMQV22100MM (100 kAIC) can be used as direct upgrades. It also serves as a replacement for the obsolete TMQD22100.
Can the TMQC22100MM be used to feed a three-phase tenant panel?
No, this is a 2-pole breaker that provides single-phase output. While it can be connected to a three-phase horizontal bus within a Meter Mod III stack, the tenant feed will remain single-phase (120/240VAC).
Can I install the TMQC22100MM in a standard GE PowerMark Gold load center?
No, the TMQC frame features a specialized bolt-on design engineered exclusively for GE Meter Mod III modular metering stacks. It is not compatible with standard residential load centers.
