flood plain. In some applications, particularly on floating docks, power supplies can be mounted
Inside of existing dockside power pedestals by licensed marine electricians following Class 2 wiring
requirements.
2 Never allow your connections to become submerged. Ensure all connections are kept out of the water.
3. Power supplies must be connected to 120/240VAC in accordance to the National Electrical Code and
any local electrical codes. All power supplies MUST BE CONNECTED TO A GROUND FAULT CIRCUIT
INTERRUPTER (GFCI) PROTECTED CIRCUIT.
Power supply requirements
A suitably fused 24v supply is required for each light. DO NOT CONNECT DIRECTLY TO MAINS AC! A 4
Amp fuse / breaker is recommended for each light.
When selecting the mains AC to DC converter(s) it is important to ensure that the overall power
requirements are met, allowing a ‘reserve’ of at least 15% of the overall power to allow for losses in cable
runs. The recommended power requirements are shown in the table below:
Number of D16 lights
Max Current draw

44.3 W

When connecting multiple lights to one power source the OceanLED 4-way junction box is recommended
as this provides four independent separately fused outputs for each light.
Power Cable selection
It is important to select the correct size cable for the supply to the dock lights. The required cable gauge
depends on the current draw and the length of the cable run from the power source to the light(s). Note
that where the power source is remote from the power junction box connected to each light, this cable
will carry the total current for all the connected lights, and should be sized correctly to prevent excessive
voltage drop and power loss.
The cables from the power junction box to the lights themselves can be a smaller gauge, but again should
be correctly selected depending on their length to prevent excessive voltage drop. The diagram below
shows a typical example of this:
The table below should be used to select the required cable conductor size. If in doubt always select
the next larger conductor size up (i.e. the next lower AWG number). Ensure all connections / joints are
watertight, and suitable for the current load.
NOTE:
THE SUPPLY CABLE MUST BE PROTECTED BY A SUITABLE FUSE OR BREAKER.
