ESD Prevention & Dock Safety Testing MN: GFPE Breakers

Electric Shock Drowning (ESD)

It's known as the "Silent Killer." AC electricity leaking into fresh water can paralyze a swimmer in seconds, causing them to drown. We find the leaks before they find you.

Why Breakers Don't Trip

A standard circuit breaker only protects wires from overheating. It WILL NOT detect 2 amps of current leaking into the lake—but 0.1 amps is enough to kill a human. You need specialized protection.

Safety Audit Process

We perform comprehensive inspections of lakeshore properties to identify "hot docks" and dangerous wiring faults.

Step 1

Visual Inspection

We check for the most common causes of ESD: loose ground wires, corroded connections, and non-marine rated cables. We verify that the bonding bridge connecting the dock frame to the electrical ground is intact.

Step 2

Voltage Testing

Using specialized voltage gradient probes, we measure the electrical potential in the water around your dock while circuits are energized. This reveals invisible current leakage that may be coming from your boat lift or even a neighbor's dock.

Step 3

GFPE Installation

We retrofit 30mA GFPE (Ground Fault Protection of Equipment) breakers. These devices constantly monitor current flow and cut power if a significant leak is detected, protecting your feeder cables and equipment.

Protection Levels Explained

Fire Only

Standard Breaker

  • Trip: 15,000mA+
  • Protects: Wires from melting.
  • Safety: NO protection for swimmers.
People

GFCI Outlet

  • Trip: 5mA
  • Protects: People from shock.
  • Cons: Nuisance trips on motors.
Equipment

GFPE Breaker

  • Trip: 30mA
  • Protects: Equipment (Boat Lifts) from faults.
  • Pros: Ideal for hardwired lifts.

Real-World Testing

No swimming due to electric shock risk sign

We don't just guess. We use calibrated probes to map the voltage gradients in your water to find the source.

  • Voltage Mapping: We identify exactly where the current is leaking—your dock or the neighbor's.
  • Bonding Check: We verify the equipotential plane of your dock frame.
  • Report: You receive a documented safety audit for your peace of mind.

Don't Guess on Safety

If you feel a tingle in the water, GET OUT immediately and turn off power. Do not swim until the issue is resolved.
