Cable & Wiring Guidelines for 12VDC / 24VDC Lighting Installations You must always consult with a qualified electrical contractor to determine the correct methods and equipment required for your particular project. Prior to commencing any installation, all details should be confirmed by your qualified electrical contractor to ensure the correct outcome.
Outdoor LIghting Installations
12VDC or 24VDC LED installations require the same consideration as any other low voltage installation, and the same wiring and voltage ‐ drop considerations apply.
Low voltage connections in exterior locations must be made using professional junction box and gland terminations. Only a round cable (or a round conduit) is suitable. The use of any type of heat-shrink or tape joins in exterior or wet locations are not acceptable. For very wet areas or underground installations, the junction box should be resin encapsulated
Voltage Drop
A higher wattage total load and/or a longer cable run may require larger conductor size to counter voltage drop. Voltage drop calculations for LED lighting installations are identical to any other low voltage cable installation - consult your qualified electrical installer for more information.
Correct Polarity and Wiring Installation
LED lighting products require the correct polarity to operate correctly, so always ensure wires are appropriately labelled or marked so that the correct polarity is terminated. Short circuits can cause permanent damage. Always ensure professional terminations and ensure controllers and LED drivers are not overloaded. Always use the appropriate length of cable for each of the cable runs. It is not acceptable for cables to be pulled tight or to have any mechanical strain on electrical cables. It is not safe to have significant excess cable coiled or bundled after the installation.
Number of Conductors
Single colour 12VDC and 24VDC LED products require 2 ‐ wires (2 conductors).
12VDC and 24VDC RGB products require 4 ‐ wires (4 conductors). The 4 conductors do not need to be in a single cable. Eg two 2 ‐ core cables can be used to achieve 4 conductors.
12VDC and 24VDC RGB+W products require 5 wires (5 conductors).
Use Correct Cable Type
Flexible type cable (multi stranded cable) is recommended because it is easier to terminate into terminals on controllers and other devices. Outdoor or exposed cable runs should have appropriate UV protected sheath. Product failures that are the result of incorrect installation, or installations that are not carried out in accordance with guidelines will void any product warranty.
It is the sole responsibility of the installer to ensure all installations are carried out in accordance with all applicable laws and applicable wiring rules.
