Here is a short guide to different types of cable commonly used in domestic and light commercial buildings.
In many applications such as schools, hospitals and retail, low smoke halogen free cable types are taking over from PVC cables. Examples are BS 7211 installation wiring and BS 6724 armoured power cable.
Electricians are increasingly asked to install complex systems involving a combination of power and data cables, such as distributed security using ‘power over Ethernet’.
Demands by architects for more open buildings has made fire protection systems more complex and challenging for power supplies. New cable types have been developed, which need additional understanding when installing them, for example the new BS 7846 types.
When installing electrical products and systems you must ensure all the necessary electrical installation verification tests have been performed. For example: earth loop impedance and ring continuity.
A non-profit making Government–nominated body, BASEC has for more than 30 years been a mark of reassurance to those specifying cable. The leader in product certification services for electrical cables, data and signal cables.
All products are rigorously tested to meet necessary and appropriate British, European and international standards through detailed examination of manufacturers’ production processes and controls.
