10 mm Single Core Conduit Cable 6491X Blue & Brown & Yellow/Green Ali's DIY - 1 Metre Cut Length

Product Information

Another cable used a lot in domestic lighting is called 3 core and earth. The extra core (wire) is in an insulating sheath and is used as an extra conductor to carry power between 2 or more switches operating lights. The nominal cross section of each conductor has to be chosen that the current-carrying capacity is not smaller than the max. constant current, passing the conductor under normal conditions. The limit temperatures to which the current-carrying capacity refers to, shall not be exceeded for the insulation and sheath of the corresponding cable types. A defined condition is also the type of laying of the used cable. This has to be considered for the determination of the allowed load currents. Conditions that have to be considered are among others:

As with most formulas in the building trade there are regulations defining specific boundaries for the use of all materials. Factors such as resistance and voltage drop may need to be assessed and taken into consideration when working out cable runs.This can be further complicated by the location in which they will be installed and how effectively a given cable will be able to disperse heat e.g. a cable installed in an empty stud wall will dissipate heat much easier than a cable in a loft that buried under 200mm of insulation, so this needs to be considered also. They have suggested, through surveys, that almost half of all severe electrical injury caused in the home is due to DIY work. The most common causes being drilling through wires in the wall, cutting through cables and not turning electrical circuits off before working on them! It is also worth stating that years ago, the cable colours used in the UK were changed so that they harmonised with those used in Europe. To learn more about this, see our wire and cable colours project here. We do not sacrifice the quality of our products to keep prices down. We have seen companies start and fail by selling poor quality goods at what seem to be 'bargain' prices. We will not advertise or supply poor quality imported products just to display the lowest price. Also taken into consideration is the temperature of the area or void, the length of the cable run, the grouping of the points they serve and the type of device (Fuse, RCD etc.) by which they are protected.

Please, if you are doing and electrical work, make sure you have the right VDE approved tools for the job and do not be tempted to save money by buying cheap imitations which will not be anywhere near as well insulated.Aside from the 3 most commonly used cable sizes of 1, 1.5 and 2.5mm twin and earth there are in fact numerous other larger sizes of cable that include 4mm, 6mm, 10mm and 16mm. These are mostly used for appliances and objects that require much more electrical power to operate or special use situations. Even larger sizes of cable include 25, 35, 50, 70,95, 120, 150 all the way up to 1000 square mm, over 20 different sizes in total, but anything above 16mm is generally just for industrial use. For the benefit of reason, it is as well to explain that competent does not simply mean you can walk, talk, read and write.
