Does this interlock fit a RC816F Square D combination meter and main disconnect panel?

Hello Frank, Generator Interlock Kits are available ONLY for certain CSED catalog numbers and the below catalog numbers are the ONLY devices that can be used with a generator kit. Any other CSED catalog number would NOT allow the use of a generator kit. The RCGK2 can be used with the following catalog numbers: "RC816F_ _ _C" or "RC816F_ _ _CH" and "RC2040M_ _ _C" or "RC2040M_ _ _CH" or "SO2040M_ _ _S". Where the '_ _ _' is the amperage of device. The QCGK3 can be used with the following catalog numbers: "QC816F_ _ _C" or "QC816F_ _ _CH" and "QC2442M_ _ _C" or "QC2442M_ _ _CH". Where the '_ _ _' is the amperage of device. The HOMCGK2C can be used with the following catalog numbers: "RC816F_ _ _(S / SH / SL / SS / SLS / SHS)" and "RC2040M_ _ _(S / SH / SS / SHS)" and "RC3040M_ _ _(SL / SLS)" and "RC3042M_ _ _(PS)". Where the "_ _ _" is the amperage and the letters in the ( ) would be potential suffixes of the catalog number. The QOCGK2C can be used with the following catalog numbers: "QC816F_ _ _(S / SH / SL / SS / SLS)" and "QC2442M_ _ _(S / SH / SS / SHS)" and QC3040M_ _ _SH". Where the '_ _ _' is the amperage of the device and the letters in the ( ) would be potential suffixes of the catalog number. Regards, Customer Care Center
