An important step in preventing water-related electrical tragedies is to ensure correct installation and maintenance of boats, as well as docks & dock systems. Take the time to inspect all electrical components near or on the water. You wouldn’t put a leaky boat into the lake, so make sure all other operations are safe.

Dock SystemWhen it comes to docks & dock systems, take note of the following:

  • All electrical installations must comply with the National Electrical Code, which requires a GFCI (Ground Fault Circuit Interrupter) on all dock receptacles.
  • At least once a month or as per the manufacturer’s specifications, the GFCI should be tested.
  • There should be bonding jumpers on the metal frames of docks to connect metal components to a ground rod on the shore. This ensures that any metal components that become energized due to electrical malfunction will trip the circuit breaker or GFCI.
  • Even if your dock’s electrical system has been correctly installed and inspected, your neighbor’s dock can still present a shock hazard. Therefore, make sure his or her electrical system also complies with the National Electrical Code and that it has been inspected.
  • Because docks & dock systems are exposed to the elements, they should be professionally inspected at least once a year.

Important Note: If you feel a tingle while swimming, get out of the water as quickly as possible, avoiding metal objects and metal ladders. When fishing or boating, be aware of your surroundings and possible electrical hazards.
