Boat Dock Wiring: What Lake Homeowners Should Know

Around Cedar Creek Lake and Richland-Chambers, a lot of homes have a dock with lights, outlets or a boat lift. Dock wiring lives in the harshest conditions on the property, and when it goes wrong around water it can be deadly. Here's what to know.

The real danger: electric shock drowning

A wiring fault on a dock can leak electricity into the water around it. A swimmer can be paralyzed by the current and drown, often without any visible sign of a problem. It's one of the main reasons the electrical code has specific rules for docks.

What safe dock wiring looks like

• Ground-fault protection on the dock circuits, so a leak shuts the power off fast.
• Wet-location parts: weather-rated outlets with in-use covers, and fixtures made for the conditions.
• Protected wiring runs in proper conduit, secured above the high-water line where possible.
• Dedicated circuits for lifts and other big loads.
• A clear shutoff on shore that everyone in the family knows how to find.

The National Electrical Code has a dedicated article for docks, and its requirements have tightened in recent years. A dock wired a decade ago may not meet them.

When to have your dock inspected

• After high water, a storm or any damage to the dock
• If breakers or GFCIs on the dock trip often
• When adding a lift, lights or outlets
• When you buy a lake home
