On Captiva Island we installed a new 50-amp shore power receptacle for a boat on a dock piling, and on the same property we wired the pool equipment panel.

  • Location: Captiva Island, Florida
  • Service: dock shore power and pool equipment wiring
  • Equipment: 50-amp shore power receptacle, outdoor-rated Square D disconnect, 120-volt receptacle, Pentair pool equipment panel

The dock

  • Installed a new 50-amp shore power receptacle for a boat on a dock piling.
  • Mounted an outdoor-rated Square D disconnect above it, with a 120-volt receptacle on the same piling under a clear weatherproof cover.
  • Protected the shore power circuit with a 50-amp, 30 milliamp ground-fault equipment protection breaker.
  • Ran the wiring down the piling in conduit.

The pool equipment

  • Wired a Pentair pool equipment panel.
  • Connected two pool light transformers, one for the spa light and one for the pool light.
  • Wired a 120-volt electronic pool water leveler.
  • Ran a 50-amp circuit for the pool heater.

Why the shore power breaker is different

Shore power for boats is protected with ground-fault protection of equipment (GFPE) that trips at 30 milliamps, as NEC Article 555 requires for shore power receptacles. A standard GFCI breaker trips at a much lower level, around 4 to 6 milliamps, and often trips for no real fault on docks and boats. The 30 milliamp breaker is the correct protection for every shore power receptacle and avoids those nuisance trips.
