Install 2 customer supplied fans on back deck The reason for today’s visit was to look at installing the wire back on their new deck. Customer previously had a deck with existing wiring however, when they replaced the roof, they never installed it back. The existing UF wire was in PVC up the side of the house in the back right corner where the deck starts. We ended up installing two new ceiling fan locations as well as two new receptacles. We converted the PVC over to flex and installed it into the ceiling of the deck and installed a junction box over by the security light. We ran in all wire in 12/2 UF cable.
