Below are links to pages which will display a table of technical specifications for SWA Cable dependant on core amount:- Cable Length Step 4. Particularly, considering a 2.5 mm2 conductor clipped direct (Reference Method C) has current-carrying capacity of 27 A (Table 4D5 of Appendix 4 refers). For more cable types, use the Cable sizing calculator AS/NZS3008. In this case, the specifications are dictated by the Core count. BS5467 SWA/PVC Cable IEC 60502 600/1000V Current Ratings and Electrical Data TWO CORE: REF 6942 XWP Size Sq.mm Max conductor resistance at 20°C Conductor short circuit rating (1 sec) kA Armour short circuit rating (1 sec) kA Current ratings Volt drop single phase AC touching mV/A/m Direct in ground Amps In duct Amps In air Amps Notes: Where it is intended to connect the cables in this table to equipment or accessories designed to operate at a temperature lower than the maximum operating temperature of the cable, the cables should be rated at the maximum operating temperature of the equipment or accessory (see Regulation 512.1.5). The ampacity of a conductor depends on its ability to dissipate heat without damage to the conductor or its insulation. Step 2. The following chart is a guideline of ampacity or copper wire current carrying capacity following the Handbook of Electronic Tables and Formulas for American Wire Gauge. Heat, caused by an electrical current flowing through a conductor, will determine the amount of current a wire will handle. 3 - Enter max amps to be carried by the cable [amps = watts / voltage]. This corresponds to a 14 AWG cable in the Table Of Common Cable Sizes above. Welcome to Lapp Kabel - your partner for high performance cabling solutions! voltage drop = 0.36 volts; gives a cable cross-sectional area of 1.53 sq. The Current Carrying Capacity of SWA Cable dictates the current rating, as well as other technical specifications, of a certain type of SWA Cable. Cable Sizing Selection Chart Step 1. ElectricalDesign References BS7671 Cable current-carrying capacity Table 4D4A PVC Insulation / Copper / Multi-core / Armoured Table 4D4A PVC Insulation / Copper / Multi-core / … The current rating must be multiplied by relevant rating factors as in the below tables. Voltage Drop Calculation Examples. The values shown illustrate the impact of these Installation Methods on the current-carrying capacity of the cable. This is well within the 13 amp current carrying capacity of our cable so the 1.5 twin and earth cable will be fine for the job. mm.

The cable rating that is displayed in the results of the calculator is selected from Table 13 in AS/NZS 3008. The current carrying capacity of cables covered in the standard AS/NZS 3008.1 series of standards is based on “typical” ground conditions, eg soil temperature of 25°C (15°C in New Zealand) and soil thermal resistivity of 1.2 K.m/W. Table in accordance with BS EN 60228:2005 (previously BS6360) Electrical Characteristics Current Carrying Capacity (amperes) Conductor Cross Sectional Area mm² DC or Single Phase AC (1 Two Core Cable with or without protective conductor) A Three Phase AC (1 Three Core, Four Core or Five Core Cable) A Single Phase AC or DC AS/NZS 3008.1.2 deals with cables for use with alternating voltages over 1 kV.

You must use the correct size wire for the current (load) requirement of the circuit to prevent the wire from overheating. This is for thermoplastic (PVC), three- and four-core cables, unenclosed and spaced from a surface.

References have been added for aerial bundled cables. Also described as current-carrying capacity. Tables 4D1A to 4J4A (pages274 to 316) – current carrying capacity Correction factors are obtained from the following tables (dependant upon cable type and installation): Table 4B1 – rating factors for cables in air, ambient other than 30 °C (f) Tables apply to New Zealand installation conditions. Examples of Non Critical circuit are general lighting, windlasses, bait … 25mm Conductor CSA Reference Method A (enclosed in conduit in thermally Circuit Type Step 3. Now, if we change the cable run to 20 metres, then the cable cross-sectional area needed is 15.3 sq. Nominal overall diameter: 11.2mm; Current rating: 114A* *Current ratings are based on the cable being clipped direct with 2 cables in a single phase installation. Doncaster Cables is the largest British owned general wiring manufacturer in the UK. All values assume an ambient temperature of 300c and a conductor operating temperature of 700c. This is a function of the insulation temperature rating, the electrical resistance of the conductor material, the ambient temperature, and the ability of the insulated conductor to dissipate heat to the surrounds. Aluminium and Copper Current Carrying Capacity Calculation Chart in Sqmm: Aluminium and copper are the most available material in the earth, but the copper conductor carries 40% extra current than the aluminium conductor.. XLPE/PVC single core - Current carrying capacity table single phase (in Amps) Copper Conductor Insulation XLPE Maximum Conductor Temperature 90⁰C Note This is quite a crude calculation, circuit designers will take additional factors into consideration when sizing cables, for example, in large installations the length of cable (and the resulting volt drop along it, due to its resistance) will need to be considered. Current Carrying Capacity in Ampere (Amps) Based on laying in ground with an ambient ground temperature of 20°C Nominal Area (mm²) NYY type (unscreened) NYCY type (screened) 2-3 single core cables, trefoil multicore, 3 or 4 loaded cores one single core cable* 2-3 single core cables, trefoil multicore, 3 or 4 loaded cores The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor.
