Further Information

Our in-house electrician Stuart recommends using this cable for outdoor garden lighting installations. As the cable is armoured, it is also protected from damage whilst being buried for added peace of mind.
Remember to use CC6 Cable Cleats to attach the cable to any building or structure and outdoor CW20S glands to terminate the stripped ends into the required equipment. This also provides a clean and tidy installation as well as protecting the cable from any knocks or scrapes. Remember that indoor BW20S brass cable glands are also available for this cable size.

For more information on how to install armoured cable easily and safely, check out this ‘How To’ video on installing Steel Wire Armoured Cable. This is for reference during the cable installation.
