Shore Power Cord & Plug Requirements

Electrical systems and equipment used in Kodiak municipal harbors must comply with NFPA 70, National Electrical Code and Chapter 3 of NFPA 303, and the following:

1. Shore power cords and plugs must be designed for marine use, and properly sized for the electrical service provided at the shore power pedestal. Cords with current carrying capacity of less than thirty (30) amps may not be used. Typical household extension cords are not acceptable.  (See table below for cord & plug requirements).
    
2. Shore power cords and plugs must be in good condition, one continuous length without splices, taps, splitters or adaptors.
    
3. Shore power cord ground and neutral wires shall be isolated from one another. The ground shall not be used as a current carrying conductor under normal conditions.
    
4. Do not connect damaged or corroded plugs to city equipment. Clean plug pins regularly to prevent corrosion built up. Only approved electrical lubricant may be used on conductor pins.
    
5. Only use battery chargers designed for marine use. Standard automotive battery charges may not be used.
    
6. Never plug into shore pedestal under a power load. The shore pedestal breaker should not be turned on or off under a load. Turn off power at breaker inside vessel first, verify shore pedestal breaker is off, and then plug power cord into the pedestal. Turn pedestal breaker on, and then energize the power at the vessels breaker panel.
    
7. Shore power cords on floats must be routed and secured clear of walking surface to prevent trip hazards and allow for snow removal. Do not store cord on float when vessel is out.
    
8. The Harbormaster may disconnect any service that doesn’t comply with the requirements listed herein.
