Private Boat Dock Electrical by Ralph W. Ramsey
Due to a disagreement with a dock builder and having to supply support for comments I included in a recent inspection report regarding electrical installation and equipment on a the boat dock, I assembled this lsit of requirements from research.
All comments are welcome. Corrections needed if you can provide supporting source of correction. Everyone is welcome to use this checklist for business as needed.
For use by owner or resident of single family dwelling
Contact your local AHJ (Authority Having Jurisdiction) for an inspection prior to supplying power to the dock
Electrical Installation:
All electrical installations shall be in compliance with 2008 National Electric Code and as amended by AHJ
* All conductors shall be insulated copper conductors approved for the conditions of use
* Each docking facility requiring electricity shall be supplied by only one (1) set of feeder conductors from the residential house panel. One (1) single branch circuit can serve as a feeder conductor if it is connected to a feed through module GFI disconnecting means.
* Overcurrent device(s) or disconnecting means designed to disconnect all electrical power supplying the docking facility shall be located onshore and within six (6) feet of the docking facility ramp it serves
* The bottom height of the Overcurrent device(s) or disconnecting means shall be 42” above the dock walkway at the shore connection
* A grounding electrode (in compliance with NEC) shall be installed the onshore overcurrent device(s) or disconnecting means.
* An insulated grounding electrode conductor(sized in accordance with NEC, but not smaller than #6 AWG) shall be installed connecting the grounding electrode to the equipment grounding terminal at each onshore sub panel or disconnecting means enclosure(s).
* An insulated equipment grounding conductor (sized in accordance with NEC, but not smaller than #12 AWG) shall be installed inside all conduit systems with the circuit conductors.
* All conductors (Feeder & Branch Circuit) shall be sized for the overcurrent device protecting the conductors and shall be sized to not allow more than 3% voltage drop as recommended in NEC.
* Conduits, boxes and fittings approved for the condition of use, shall protect all feeder and branch circuit conductors
* All conduits shall be sized in accordance with NEC
* Liquidtight Flexible Metal conduit(with grounding bushings) or Liquidtight Flexible Nonmetallic conduit with approved fittings shall be permitted where flexibility is required in a conduit system such as hinge points of ramps and floating structures subject to elevation changes due to changes in water levels.
* All non-current carrying metal parts of docking facility such as metal piping, metal equipment enclosures, metal frames of the structure and ramps, ,metal swim ladders and other metals in contact with the water or may become electrically energized shall be electrically bonded to the equipment grounding system
