Exposed cable is unsafe and untidy, so it is routed in a tray, duct or conduit. Metal trays are used for many cables and for industrial and commercial sites, where strength and fire resistance matter.
A plastic cable duct is a tidy solution for home and office walls: it hides the cable in a decorative channel. Flexible conduit protects cable inside walls and ceilings — easy to bend and replace.
When choosing, consider the number and cross-section of cables, the environment (indoor/outdoor, damp) and the fixings. The Electrica Group catalogue has metal trays, plastic ducts, conduit and fixings for the whole line — the "For Long Life" way.
