How to Wire an Above-ground Pool Pump
Time Required: 2-4 hours
Presented by This Old House
- Working with electricity around a pool can be dangerous. Hiring a licensed electrician is recommended.
- Before doing any electrical work, ensure the power is turned off at the circuit breaker.
- Dig a 24-inch deep trench for the underground wire.
- Drill a hole to the inside of the house where the electrical panel is located. Use an extension if needed to get through the wall.
- Fish two 12-2 nonmetallic cables through the hole into the basement, then attach them to a plastic electrical box.
- Run conduit from the box into the trench. Continue the conduit into the trench and then into the post.
- Feed three individual 12-gauge wires through the conduit into the post.
- Mount the timer to the wall.
- Wire the twist-lock receptacle.
- Plug in the pool pump and cover it with a weatherproof cover.
- With the main service off to the house, wire in GFCI circuit breakers to the electrical panel.
- Connect an 8-gauge wire to the metal posts of the pool, the pump, and the metal plate on the skimmer and then wire that to the pump to bond the entire pool.
