Guardian Auxilary Transfer Switch Contact Kit p/n 5621
The auxilary transfer switch contact kit allows a single large electrical load to be locked out from the generator operation. If a home is equipped with electrical heat or multiple central air conditioning units, this device allows the generator transfer switch to interrupt the control wire, breaking the signal needed for the appliance to turn on.
Installation Information
Once installed, the control wire must be run from the appliance to the transfer switch to connect to the contact.

Not compatible with Generac 50 Amp Pre Wired Automatic Transfer Switches.

My Mom and Dad are both in their 80's and live in the country. With the installation of the 6551 I can rest assured that they will never be without power, heat, ac and water. this is a great unit and worked perfectly upon startup. Should have installed this a lot sooner for them.

By the way, my son-in-law also has one for his home. I live in a motorhome or I would have one also.
