Most domestic cables carry a blue wire which is usually for the neutral current a brown wire for a live current and a bare wire to take residual current to earth.

Twin and earth cable ratings.

For example if you check the manufacturers current rating for 1 5 twin and earth cable suitable for most lighting circuits in a domestic environment it will state that it is around 20 amps but this value would only apply if the cable was in free air as it can cool easily. Domestic electric cable is usually available to british standard bs 6004. This cable is called 2 core and earth or twin and earth. A cable can carry many wires depending on the job it needs to do.

It has a temperature rating of 70 c including the temperature rise from resistive heating in the cable. When considering cable ratings care needs to taken as this is not as straight forward as it may seem. Ratings do not apply if the cable is protected by a semi enclosed fuse to bs3036. Installation methods 100 103 typically associated with new domestic and similar premises are specifically for flat twin and earth cable in thermal insulation.

It can be installed in fixed wiring installations in dry or damp premises clipped to surface on trays or in free air where there is no. For two way light switches opt for our 3 core and earth cables. Where cables are installed using these installation methods the current carrying capacity of the cables should be determined using table 4d5 of appendix 4 70ºc thermoplastic. For cables of 5 cores and above it is assumed only 2 cores are loaded simultaneously ie live and neutral and the 2 core rating should be taken.

For general internal power cables shop our twin and earth cables. General internal cable three plus earth armoured cable. Not sure whether this is sufficient to support all downlights and powperpoints there are about total 45 downlights and 25 powerpoints through the house. Twin and earth cable is normally made with pvc sheathing and insulation which has an almost indefinite life in the right conditions.

Our basec approved twin earth cable also known as t e is a flexible flat sheathed mains electricity wiring cable used in a wide range of domestic electrical applications with a voltage rating of 300 500v. However uv light will cause it to fail so twin and earth is not suitable for use outdoors. For 2 core single phase a c 3 4 core three phase a c. 31st march 2004 saw the introduction of a new colour code harmonised across the eu for power cables see this page for details of these changes.
