Boat Dock Wiring, Done Right Over Water.
Dock power, lighting, and boat lift circuits on Old Hickory, Percy Priest, and Center Hill. Built with the ground-fault protection and bonding that water demands.
Power Over Water Is Its Own Discipline.
A dock is one of the few places where a wiring fault can energize the water people swim in. That is why docking facilities have their own rules in the National Electrical Code, and why residential docks are held to them too, not just marinas.
We run the feeder from the house or shoreline, land it in a weatherproof dock panel, and protect and bond the installation so a fault trips the circuit instead of finding the water.
- Dock feeders and weatherproof panels
- GFCI receptacles and dock lighting
- Boat lift and hoist circuits
- Bonding of metal dock framing
From Shoreline to Dock.
Walk the Site
We look at the dock type, the distance from the house, and what you want to power, then size the feeder.
Install to Code
Weatherproof panel or disconnect, ground-fault protection, wet-location fittings, and full bonding of the dock frame.
Test Before Use
We verify ground-fault protection and bonding before anything on the dock is energized.
Confidence at the Waterline.
Ground-Fault Protected
Dock circuits protected at the low threshold the code requires for shore power.
Properly Bonded
Metal dock framing, ladders, and lift structure tied together and grounded.
Wet-Location Rated
Enclosures, fittings, and devices selected for constant exposure to weather and spray.
Dock Lighting
Path, piling, and flood lighting so the dock is usable after dark.
Boat Lift Ready
Correctly sized circuits and disconnects for lift and hoist motors.
Built to Move
Flexible connections at the gangway so a floating dock can rise and fall safely.
Lakefront Homes and Docks.
We work for homeowners on Middle Tennessee's lakes and rivers, from Old Hickory and Percy Priest to Center Hill and Tims Ford, adding power to a new dock, replacing wiring that has weathered badly, or bringing an older dock up to current standards.
Docks take a beating. Sun, spray, ice, and constant movement break down enclosures and terminations that were never rated for it. When we rewire a dock, we build it for that environment, not for a back porch.
Why Docks Have Their Own Rules.
Docking facilities are covered by Article 555 of the National Electrical Code, and it applies to docks serving one- and two-family homes, not only commercial marinas. The headline requirement is ground-fault protection: shore power receptacles must be protected at a threshold no higher than 30 milliamperes, far tighter than ordinary equipment protection.
That number exists because of electric shock drowning. Current leaking into the water around a dock can paralyze a swimmer before anyone realizes there is a fault, and the code was tightened specifically to reduce those deaths. Bonding the metal dock structure is the other half of the answer.
Code editions are adopted locally and change over time, so we install to the edition your jurisdiction enforces and confirm the requirements before we start.

Boat Dock Wiring FAQs
Does a residential boat dock need special electrical protection?
Yes. Docking facilities fall under NEC Article 555, which applies to residential docks as well as marinas. Shore power receptacles require ground-fault protection set no higher than 30 milliamperes, and the metal dock structure must be bonded. We install to the code edition your local jurisdiction enforces.
What is electric shock drowning?
Electric shock drowning happens when current leaking from faulty dock or boat wiring energizes the water around a dock, paralyzing a swimmer. It is the reason the code tightened dock ground-fault protection to 30 milliamperes. Correct ground-fault protection and bonding are the primary defenses.
Can you add power and lighting to an existing dock?
Yes. We run the feeder from the house or shoreline, install a weatherproof dock panel or disconnect, and add GFCI-protected receptacles, dock lighting, and boat lift circuits, using wet-location rated equipment throughout.
Can you wire a boat lift?
Yes. We size and run the circuit for boat lift motors, install the required disconnect and ground-fault protection, and make sure the lift and dock framing are properly bonded.
