02 — Size Limits
Fitting Power on a Six-Foot Pier
The state allowance caps the walkway at 6 feet wide, and any L- or T-head platforms and floating docking platforms at 400 square feet combined. An open-sided roof over a single slip or lift larger than 700 square feet requires a full permit.
Those numbers shape the wiring layout. A six-foot walkway leaves limited room for a receptacle enclosure beside foot traffic, so the electrical plan is drawn to fit inside that footprint.

04 — Shore Power
Shore Power for the Boat at Your Pier
Article 555 of the 2020 National Electrical Code, the edition Virginia’s building code uses, applies to private residential docks as well as marinas. Its shore power rules go well beyond an ordinary outdoor outlet.
Receptacle ratings
Under the 2020 code, a shore power receptacle is located in a listed enclosure protected from the weather, is served by its own branch circuit rated to its rating, and is rated at least 30 amps. The 30- and 50-amp versions are locking, grounding types, and those rated 60 amps and up use pin-and-sleeve connectors.
Each shore power receptacle also needs its own ground-fault protection set to open at no more than 30 milliamperes.
We match the receptacle to the inlet on your boat, such as a 30-amp, 125-volt connection or a 50-amp, 125/250-volt connection.
A disconnect at the receptacle
The code also calls for a circuit breaker or switch for each shore power receptacle, marked for the receptacle it controls and readily accessible within 30 inches of it. It sits in the supply circuit ahead of the receptacle, and a breaker or switch built into a listed marina power outlet can serve that role. That puts the disconnect out on the pier, beside the boat.
05 — Boat Lift
Boat Lift Wiring and the Lift Maker’s Paperwork
Some lift makers set their own electrical conditions. Golden Boat Lifts requires its elevator lifts to have one of two features: a 4-pole disconnect switch left off whenever the lift is idle, or a removable power plug left unplugged.
Golden says the purpose is to prevent damage from electrolysis. Its notice warns that without one of those devices installed by a licensed electrician, the aluminum track I-beams may corrode or deteriorate and the warranty may be void.
Separately, the 2020 NEC requires GFCI protection at the outlet supplying a boat hoist rated 240 volts or less at a home dock, and many lift manuals say the same.
Before we wire a lift, we read its manual. The circuit is sized to the motor’s rating under the code’s motor rules, the switch or plug arrangement follows the maker’s instructions, and the control goes where you can reach it from the walkway.
06 — House to Pier
Getting Power From the House to the Pier
The run to the pier starts at your panel and crosses the yard, often past a bulkhead or the marsh edge, before it reaches the walkway.
The panel comes first. A lift motor and a shore power receptacle each require a circuit, and a 50-amp shore power circuit is a sizable load on its own. We check available space and service capacity before quoting, and a panel upgrade can be planned as part of the same project if needed.
07 — Boathouses
Boathouses, Roofs, and Lights Over the Water
Under a slip roof or inside a boathouse, we wire the lighting over the water, a sheltered spot for the lift switch, and weather-protected receptacles, using wet-rated fixtures throughout. Walkway lights are aimed down at the deck boards.
The structure itself is the marine side of the job. The state allowance names an open-sided roof, not a boathouse, and makes it subject to any applicable local ordinances, so whether an enclosed boathouse fits that allowance is a question for your marine contractor or VMRC. The wiring inside it is ours either way.
08 — Process
From Pier Sketch to Powered Lift
Read the pier drawing
Your pier plan and lift model are read against Article 555 and the lift maker’s instructions before any route is drawn.
Route and load check
We confirm panel capacity and lay out the circuits on your pier drawings.
Written estimate
You receive a free installation estimate in writing, honored for 30 days.
Permit and wiring
With the city electrical permit in place, we install the feeder, the lift circuit and disconnect, the shore power receptacle, and the lights.
Inspection and handoff
After the electrical inspection, we show you the lift switch and the shore power breaker and how each one is used.
