   The electrical cables used to power the lights and appliances in your home come in several different cable sizes, primarily to accommodate the amount of current required to run the items that are drawing power from it. All cables are rated to carry a specific amperage meaning that the load imposed on them should be no more than they are able to saf...

   The Cable sizes for domestic lighting circuits is usually 1mm or 1.5mm twin and earth cable (aka two core and earth). In most cases 1mm should be fine but depends on how many lights are on the circuit and how long the cable run is. If quite a few are required or the cable run is over a long distance, then 1.5mm cable should be used to cope with sup...

   As we have established above, how you identify electrical cable size is through the size of wire it houses e.g. 1.5mm cable houses 1.5mm wire. In most instances, the size of cable should be printed on the sheath, but if not you will need to calculate the diameter of the wire to determine its size, which means working out the area of a circle e.g. t...

   Different cables and flexes are used for different jobs because they are thicker and can carry more current and have more, or less resistance. Resistance can be thought of as electrical friction and the wires in the cable or flex will absorb some of the energy in the current, allowing a little less to reach the target than was sent. High energy use...
