Boat Lift Controller & Electrical Installation – St. James City, FL

PROJECT DESCRIPTION: BOAT LIFT ELECTRICAL INSTALLATION – ST. JAMES CITY, FL

We recently wrapped up a complete electrical installation for a new boat lift controller in St. James City, FL 33956. The project required extending conduit, pulling new conductors, installing a weatherproof GFCI outlet, and upgrading the panel with dedicated breakers—all while removing outdated electrical components on the opposite side of the lift.

• Conduit Installation – Continued the existing 3/4" PVC conduit run from the dock walkway to the new controller pole location.
• Wiring Installation – Pulled (3) #10 THHN conductors (black, white, green) from the shed junction box to the boat lift controller, plus (2) #12 THHN conductors to a new GFCI device.
• Boat Lift Controller – Installed the customer-supplied controller at the designated pole and terminated all wiring per manufacturer specifications and NEC code.
• GFCI Device Installation – Added a weatherproof box with a GFCI receptacle beneath the controller, complete with an in-use outdoor cover.
• Seal Tight Conduit & Motor Wiring – Ran 3/4" seal tight conduit from the controller to both lift motors, securing conduit with proper straps and supports.
• Demolition of Old Electrical – Removed all existing conduit, wiring, and devices on the unused side of the lift.
• Breaker Installation & Panel Work – Installed a 2-pole 30A breaker for the lift motor circuit and a single-pole 20A breaker for the GFCI receptacle in the downstairs panel.

The new setup provides safe, efficient power for the boat lift and includes GFCI protection for added safety at the dock. With new conduit, wiring, and properly sized breakers, the installation is code-compliant, reliable, and built to last in a marine environment.

How long did this installation take?
The project was completed in one day, including conduit work, panel upgrades, and the removal of old electrical.

Why was a new breaker panel connection needed?
Dedicated circuits ensure the lift motor and GFCI receptacle operate safely without overloading existing panel circuits.

What kind of wiring was used?
We used #10 THHN conductors for the boat lift motor circuit and #12 THHN conductors for the GFCI receptacle—standard for marine-grade installations.

Is the GFCI outlet weatherproof?
Yes. We installed a weatherproof box with an in-use cover, providing year-round protection from rain and splashing.

Did you remove old electrical?
Absolutely. The outdated wiring and conduit on the opposite side of the lift were fully removed for safety and to avoid confusion with the new system.
