General info about supporting cables and avoiding mechanical stresses can be found in Chapter 52

"selection & erection of wiring systems" pages 97 109.

Guidance Note 1 (Selection & erection) has some more specific info in Appendix G page 169 onwards...

basically it gives a few tables of max recommend spacings of cable clips for different environments.

Typical spacing 300mm Hoz / 400mm Vert for non -armoured cables with diameter between 9mm - 15mm.. but there is loads more table info!

low reading ohm meter with a test current of 200mA min.

if cables are not adequately supported, they will fall.
