Marina Shore Power – Conditions of Use


All vessels connecting to Shore Power must display a current Electrical Warrant of Fitness (EWoF) that complies with AS/NZS3004.2. An Electrical Warrant of Fitness is valid for a period of 4 years from date of first inspection.

Shore Power Supply Leads must be tested and tagged annually as per AS/NZS3760.

Do not connect shore power without Marina Management Approval. Marina Management must be satisfied the vessel has a current EWoF before connecting to shore power.

Marina Shore Power-Connecting to Shore Power

When connecting to shore power the onboard electrical safety of your vessel is an important factor to consider.

Unlike household electrical wiring, the electrical wiring and equipment onboard your vessel resides in a corrosive marine environment that requires regular inspection and maintenance.

For this reason, to ensure the safety of all boats residing in the marina, any boat requiring a connection to shore power must have and display a current Electrical Warrant of Fitness.

Marina Operators cannot legally supply shore power to a vessel without a current EWoF.

Before connecting to shore power, discuss your requirements with the Marina Office. They will guide you to ensure legal compliance.

Every time you connect to shore power, take a good look at the lead and fittings. If you see any evidence of damage, corrosion or arcing of the connections have it checked by a marine electrician. When connecting the plug and socket make sure the locking ring is always secured to ensure protection from the weather.

Always ensure the shore power lead is arranged so that it will permit normal movement of the boat at it’s mooring without placing undue stress on the shore power cable and does not rub, chafe or crush against movement of a boat’s fairlead’s, anchor or mooring cleats.

Marina Shore Power-Residual Current Device

All shore power modules are protected by a Residual Current Device. An RCD is an electrical safety device that provides protection by rapidly disconnecting the electricity supply should a fault to earth be detected.

As water is a good conductor of electricity, you don’t want to become the path of least resistance, always test the RCD every time you connect to Shore Power.

Always test the RCD each time you connect to shore power.

To test, connect to shore power, switch on and press the RCD test button.

The RCD should trip to the off position. It the RCD does not trip a dangerous condition may exist due to a fault.

If a fault is found to exist, disconnect the shore power and notify Marina Management immediately.

Marina Shore Power-Electrical Standards AS/NZS 3004:2008


This marina provides power for limited use on your vessel with a direct connection to the marina electrical supply, which is connected to a copper based marina electrical protective earthing system.

All vessels connecting to shore power at this marina must hold and display a current Electrical Warrant of Fitness (EWoF) that complies with the New Zealand Electrical Regulations and AS/NZS3004.2

The electrical supply at this marina is 230V, 50 Hz supplied by RCD protected socket outlets which will accommodate a Standard IEC 60309-2 (round pin) plug rated at no less than 16A.

Note: Some 10A (flat pin) outlets still exist are being replaced on failure.

Marina shore power modules and outlets are constructed with a minimum weatherproofing degree of protection of not less than IP45 in accordance with AS60529. An IPX6 degree of protection in accordance with AS60529 shall be maintained by ensuring the weatherproofing plug/socket lock ring is used at all times when the plug and socket are connected.

Connection of a recreational boat’s electrical system to the marina a.c. power supply may result in accelerated corrosion of the boat’s under water metallic parts. It is the responsibility of the boat owner to ensure that either an isolating transformer and or a galvanic isolator are installed on board in accordance with AS/NZS3004.2.

Additional sacrificial anodes or galvanic isolators complying with AS/NZS3004.2 Clause 4.6.4 may be used to reduce these effects. Also refer to AS/NZS2382 series of Standards for suitable cathodic protection practices.

The shore power supply lead shall consist of a heavy duty flexible lead complying with AS/NZS3191 or flexible cable complying with AS/NZS5000.1 and a plug that complies with IEC 60309-2. The supply lead shall be tested and tagged annually as per AS/NZS3760 and shall not exceed 25m in length and must not be connected to the electrical supply while it is coiled up.

Marina Shore Power-Shore Power Leads AS/NZS3004.1.3.2

Any supply lead used to provide electrical supply to a vessel from a marina shore power module must be tested and tagged annually as per AS/NZS3760 and shall be arranged so that it will:-

a. Permit normal movement of a boat at its mooring without undue stress;

b. Prevent water flowing along the supply lead from reaching the appliance inlet or the supply plug;

c. Minimize the likelihood of the plug or cord extension falling in the water;

d. Minimize the possibility of accidental disconnection;

e. Not present a hazard to persons walking in the vicinity of the boat; and

f. Be either –

1) Located where it will not be subject to mechanical damage by high temperatures; or

2) Provided with suitable protection against mechanical damage or damage by high temperatures.
