Need to know how thick a cable needs to be for a solar panel, fridge, battery, or motor? Use this calculator to find out Joined: 07 August 2007. I do not feel that the current carrying capacity of brass can be easily determined. Provided that one knows the type of brass, the conductivity can be looked up. In the example given above it is said to be 28%. This will clearly need a larger cross section than if using copper
A very approximate method of estimating the current carrying capacity of a copper busbar is to assume a current density of 2 A/mm2 (1250 A/in2) in still air. This method should only be used to estimate a likely size of busbar, the final size being chosen after consideration has been given to the calculation methods Universal Cable today has a broad manufacturing portfolio of cable and wire products, which includes advanced power and control cables, instrumentation cables, aluminium conductors and cables, cables for the oil & gas industry and various types of specialty cables such as welding cables and automotive cables. For 2 core - single phase a.c., 3 & 4 core - three phase a.c. - ratings do not apply if the cable is protected by a semi-enclosed fuse to BS3036. 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
Now check the selected (7/1.04) cable with temperature factor in Table 3, so the temperature factor is 0.97 (in table 3) at 35°C (95°F) and current carrying capacity of (7/1.04) is 31A, therefore, current carrying capacity of this cable at 40°C (104°F) would be; Current rating for 35°C (95°F) = 31 x 0.97 = 30 Amp Wire size is usually identified as the area of the conductor in square millimeters. The following sizes are for 60ºC insulation, copper wire, 3 current carrying conductors in a raceway. Sizes over 6 square millimeter are normally stranded so the measured diameter will be slightly larger A 10mm cable can carry between 40 and 70 amps of current. The quality of the conductor and insulator determine the current that a wire can carry. The conductor and ambient temperature play a large factor in the load capacity and the safety of the wiring.

For a first estimate of the cross-sectional area of copper you will need for this duty, I use a rule-of-thumb of around 1600 A/sq in. Based on this, to carry 700A you will need a cross-sectional. cable is rated at 27amps fuse is rated at 20amps oven is rated at 18amps . the numbers look fine to me , however there are other things to consider. i.e if the cable run travels through more than 400mm (depth) of thermal insulation the current carrying capacity of the cable has to be halved so the cable will become the weakest link in the chain Designers of low voltage power circuits are often unaware of the implications of voltage drop and wire size. In conventional home electrical systems (120/240VAC), wire is sized primarily for safe amperage carrying capacity (ampacity). The overriding concern is fire safety. In low voltage systems (12, 24, 48VDC) the overriding concern is power loss
12 Volt Wiring Gauge Requirements at specific Amps to length for Automotive Electrical Systems . Wire uses the measurement of gauge to determine the size of the wire. The larger the wire, the smaller the gauge number. To find the required wire gauge for a specific application, you must know the current draw of the accessory on the circuit. 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. 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.
