Up for sale is one 8 year old generac transfer switch. I recently changed to a 200 amp service and couldn't reuse this switch for the new service. YOU HAVE TO HAVE A 100 AMP SERVICE FOR THIS TO WORK, A 200 AMP SERVICE IS TO MUCH. it works fine and it is so new I couldn't see just throwing it away. Make a reasonable offer and it's yours.
