Product FAQs
6 answersWhat panelboards and meter stacks are compatible with the TMQD22080?
The TMQD22080 is designed for use with GE A-Series Panelboards and GE Meter Mod III Meter Stacks. It features a bolt-on connection for secure installation.
What is the difference between the GE TQD22080, THQD22080, and TMQD22080?
The primary difference is the short-circuit interrupting rating. The TQD22080 is rated at 10kAIC, the THQD22080 is rated at 22kAIC, and the TMQD22080 offers an extra-high interrupting capacity of 100kAIC at 240V.
What wire sizes are accepted by the load side lugs on this breaker?
The load side lugs on the TMQD22080 accept 6 AWG to 1/0 AWG copper or aluminum conductors.
Does the TMQD22080 include line side lugs?
No, this is a bolt-on circuit breaker. The line side bolts directly to the panelboard or meter stack bus, while the load side features standard mechanical lugs.
Are the trip settings adjustable on the TMQD22080?
No, this breaker features a non-interchangeable thermal-magnetic trip unit with fixed long-time and fixed instantaneous (LI) trip functions.
Can I use the TMQD22080 to replace an older 80A TQD or THQD breaker?
Yes, the TMQD22080 shares the same physical dimensions and bolt-on mounting as the TQD and THQD series. It can be used as a direct replacement or upgrade, as its 100kAIC rating safely exceeds the requirements of the 10kAIC and 22kAIC versions.
