Great question. Unfortunately we don't offer an interlock kit for a load center with the old main breaker in the vertical orientation. It is offered for a variety of meter socket load centers...THQLLX4 Thanks
This will fit this panel but it is design to not allow the main breaker to be turned on while the power has been transferred to a generator. This panel does not has a main breaker.
John, Thanks for the question. This will not fit a 100 amp panel. It fits panels between 150 amps through 225 amps. Thanks Jeff
It should work on any TM3220 series breaker box
Yes it is. Piece of cake to install!
Yes this will work with that load center but you must also install a THQMV200DP which converts the TLM3220CCUMOD6 main lug only panel to a main breaker panel. You must have a main breaker panel to use the THQLLX1.
Thank you to you and Sam123 for your question. Yes, the THQLLX1 is the correct interlock for TM2020CCU series panels.
If you are talking about the GE Model# TM4020C80K panel it should work. I have attached a stock photo of this model numbers front panel and a photo of the interlock installed on our GE panel. The breakers knockouts look the same. Please note that our panel was installed upside down with the main on the bottom.
My load center is a TM32 series. You will have to consult with GE or the mfr of the interlock to find out
