We provided pricing to install manual transfer switch next to the existing 1960s main panel for a customer be able to run a few circuits in the home on the generator when power is lost. We are unable to install a generator interlock kit in the panel due to the age of the panel. We highly recommend replacement of the panel with a new larger panel to accommodate the current circuits as well as any future. With this second option, we are able to install in our lock kit, so customer can control the entire home and pick and choose what they want one when they want them on when the generator is powering home.
