Alarms have various limitations. See “Limitations of Stray Electricity Detectors” for details.
Calling a Qualified Electrician to Find and Repair the Problem
If the Dock Lifeguard units detects stray electricity in the water. Contact a local electrician that is
familiar with local electrical codes on boat docks to diagnose and solve the problem.
If You Suspect a Problem
