Product FAQs
6 answersWhat type of equipment is the TMQC22110MM designed for?
This breaker is engineered to serve as a tenant main circuit breaker in GE Meter Mod III modular metering stacks.
What does the "MM" suffix mean in the TMQC22110MM part number?
The "MM" suffix indicates that the breaker comes with the required mounting kit for installation into 125-amp or 200-amp single-phase residential meter sockets within GE Meter Mod III modular metering stacks.
What wire sizes are accepted by the factory lugs on this breaker?
The included lugs are rated for both copper and aluminum conductors, accepting wire sizes ranging from 4 AWG up to 4/0 AWG.
Is this a General Electric or an ABB circuit breaker?
ABB acquired GE Industrial Solutions, so this Q-Line breaker may arrive in packaging branded by either ABB or General Electric. The physical product and the TMQC22110MM catalog number remain exactly the same.

Installation must be performed by a qualified electrician. Ensure the metering stack is completely de-energized before bolting the breaker to the bus, and verify that all lug connections are torqued to the manufacturer specifications printed on the breaker label.
