Cable Protection & Management

A brush faceplate lets cables pass neatly through a wall, with the brush covering the opening. Knightsbridge makes the NETBRUSH2 1G (86 x 86 mm) and the NETBRUSH4 2G (147mm x 86mm), assembled in white ABS and rated IP20, and suggests them for achieving a floating TV look. Cables are not included, so run and terminate them separately.

No, Knightsbridge says its brush modules are not intended for use alongside other modules in the same faceplate or alongside power sockets in the same channel, because hazardous voltage may be present and easily accessible. The NETBR2GW (50 x 50mm, white) and NETBR4GGY (100 x 50mm, grey) are euro modules that give a tidy cable entry and exit from the wall.

Use an IP68 gel junction box or cable connector sized for the cable. The JB0014 (3-way) and JB0015 (4-way) gel boxes are rated 24A, come with cable sleeves and a lever connector, and take H07RNF cable from 0.75mm² to 2.5mm². The JB003 3-way connector, rated IP68 at 2 bar, suits outdoor and underwater wiring on H07RNF 3G cable up to 4.0mm².

The Knightsbridge JB006 M20 glands take cables with diameters of 6-12mm and fit 20mm knockouts. The JB006 glands are IP66 rated, made from robust hard plastic for indoor and outdoor use, and come in a pack of 10. Measure the outer diameter of the cable you are running and check it falls inside the gland range before you fit it.

Choose a tie long enough to go round the bundle with enough tail to pull tight. Mercury nylon ties here run from 140mm to 380mm long, in black or white and packs of 100. Sizes include 3.6 x 140mm, 2.5 x 200mm and 4.8 x 380mm. Mercury quotes a maximum load of 181lbs for every tie here.

A cable tidy unit is a box that gathers loose cables to keep a space organised and tidy. The D-Line 788.020UK (large, 0.71 kg) and 788.024UK (small, 0.42 kg) are white units with 3 cable entry and exit slots, and D-Line says the range comes in 2 sizes and various colours.
