MarinaGuard® - Helping Miami Prevent Electric Shock Drowning

Bender's MarinaGuard is a critical component to helping prevent ESD from occurring.

What is electric shock drowning?

Electric shock drowning (ESD) occurs when a swimmer is exposed to stray electric currents that fatally inhibit their ability to breathe or swim properly, resulting in drowning. ESD is most often caused by a ground fault from an electrical device on or near the shoreline. ESD risk is exceptionally high for swimming children but can also affect adults and people merely wading in water.

Where is ESD a concern?

ESD poses a potential threat in various bodies of water. Marinas, in particular, present a higher vulnerability due to electrical equipment such as electrical outlets, boat power systems, lighting fixtures, and boat lifts. Additionally, the connection of boats to shore power at marinas can contribute to ESD risk. This hazardous occurrence takes place when an electric ground-fault current unexpectedly shocks individuals swimming in close proximity. In severe cases, the shock can cause paralysis that inhibits a person’s ability unable to swim and can result in fatal consequences.


How does MarinaGuard reduce ESD risk?

To mitigate the risk of ESD, Bender's MarinaGuard panels provide a vigilant solution by continuously monitoring the feeder and branch circuits that supply electricity to marinas, boat yards, docking facilities, and similar locations. These panels swiftly identify the presence of ground faults, triggering the MarinaGuard system to deactivate the respective circuit and emit a prominent red strobe light. This visual alert effectively notifies individuals in the vicinity about the potential danger, ensuring enhanced safety measures.

MarinaGuard offers UL 508A industrial control panels with two monitoring options: single-circuit or twelve-circuit. Each circuit has an adjustable trip level, allowing you to tailor it to the specific code requirements applicable to your situation. These panels employ current transformers that measure the ground-fault current, and they are available in various sizes, shapes, and core types to cater to diverse needs.
