The provisions of this section of Part 3 in the 2002 BSS Standards are mandatory for non-private boats where applicable.
Cables should be run as high as possible to reduce the chance of heat or impact damage - at least 75mm (3ins) and ideally 125mm (5ins) away from any potential sources.
Cable conduits can be the 'clip together' uPVC type, galvanised steel or wood. But whatever the type, they must be firmly fixed at around 900mm (3ft) intervals. To minimise the chance of sparks coming off a damaged cable and igniting nearby fuels, cables must be kept at least 30mm (2ins) away from fuel and gas pipes - unless the pipe or the cable is in a suitable conduit or duct.
