The current rating is in Amps and is intended to help you choose the appropriate thickness cable for your application. Don't have a login? All wires have a resistance (although it is designed to be low) which causes wires to heat up under load. Below are links to pages which will display a table of technical specifications for SWA Cable … GWI. Because of less electrical resistance a thicker wire carries more current with less voltage drop than a thinner wire. Circuit Type Step 3. Fault current I = Uo = 230 = 164 Amp Zs 1.40 From the graph depicted in fig 3.1 (BS7671 Appendix 3), a fault current of 164 Amps would cause a 20 Amp BS1361 type fuse to operate in just … PVC Singles), non-armoured with or without sheath. Essentially the current limit is a thermal limit, related to how much heat the cable can dissipate. AWG is sometimes also known as Brown and Sharpe (B&S) Wire Gauge. The temperature ratings of wire and cable products are key operating parameters. In addition to wire size, the table provides values load (current) carrying capacity, resistance and skin effects. (LSFLEX® XL-20 Insulation) 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 … Cable … Step 2. In instances where several cores are loaded simultaneously, the following rating factors should be applied to the 2 core current rating. The higher the gauge number, the smaller the diameter, and the thinner the wire.

Cross Section (mm 2) Approximate Overall Diameter (mm) Current Rating… Values are in Amps and based on ambient temperature of 40°C in air, 25°C in ground, maximum conductor temperature of 90°C. When considering cable ratings care needs to taken as this is not as straight forward as it may seem. Operating temperature of the conductor, ambient temperature and type of conductor insulation is important. TACW: Tinned annealed copper wire… Table 1 lists the AWG sizes for electrical cables / conductors. Correct Cable … Resistance Notes: The resistance noted in the table above is for copper wire conductor. The current carrying capacity of 16 sq mm copper cable with PVC insulation is 61 amperes for single phase AC or DC. Skin Effect and Skin Depth Notes: Skin effect is the tendency of an alternating electric current (AC) to distribute itself within a conductor so that the current density near the surface of the conductor is greater than that at its core.
