IMPORTANT PLEASE READ: After the video I had this inspected. Inspector made me add a nipple between the 2 panels so the wires had protection. I also removed the neutrals from the bus and connected them to each branch circuit. DO NOT RELY ON THIS VIDEO AS A "how-to". CONSULT WITH A PROFESSIONAL ELECTRICIAN AND GET IT INSPECTED!

DISCLAIMER: Do not attempt this unless you are fully competent with electrical wiring. Failure to follow all instructions can kill you! Consult a professional electrician for guidance. This is how I wired and tested the Generac generator transfer switch. Generac's instructions are horrible. PS: if you're an expert electrician and have a better way, please share your video on how to do this. This was my interpretation based on their instructions.
