The spa panel must be mounted to the wall and connected to an electrical breaker panel with the conduit. The conduit then runs from the spa panel to the actual hot tub to supply power to the device. When running the conduit from breaker to spa panel and the hot tub, use the fittings to secure the conduits. Some conduit runs may require special fittings like sweep fittings to provide a gently sweeping movement to avoid wire pulling. After the conduit has been set, use PVC cement to cover and protect the conduit.

Once all existing wires have been stripped safely, the red and black copper wires can feed the spa panel electricity. White copper wire attaches to the line neutral bar. Green copper wire typically grounds the electrical line.
