Established in 2008 cabrical has grown over the last 11 years to become the definitive resource for cable accessories in johannesburg south africa.
Table electrical cable size chart south africa.
Today we are here with another comprehensive copper and aluminum wire size calculator as we have discussed in detail the topic of how to calculate the proper wire size for electrical wiring.
To help you work most efficiently we ve created a number of calculating tools to aid in your wire and cable installations.
Wire number gauge standard wire gauge swg american wire gauge awg gauge.
Common sizes include 14 12 10 8 6 and 2 gauge wire.
In 2016 aberdare cables was acquired by a chinese cable manufacturer hengtong.
Aberdare cables has 3 manufacturing sites in south africa with customer service centres in each province and in maputo.
Electric cable the purpose of electric cable is to convey electrical energy from the point where it is available to a point where it is required.
In order to do this safely and reliably the cable needs certain attributes.
Larger wire sizes those with a greater diameter will have less voltage drop than smaller wire sizes of the same length.
The voltage rating of the cable must be equal to or greater than the voltage rating of the system into which it is.
Wire gauge refers the physical size of the wire rated with a numerical designation that runs opposite to the diameter of the conductors in other words the smaller the wire gauge number the larger the wire diameter.
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.
Now you can take the advantage of this calculator to do this job j you can also check the classical wire cable size calculator in awg calculating wire cable size formula for single phase circuits.
Wire is sized by the american wire gauge awg system.
Products available include insulated terminals cable glands copper lugs ferrules power products pvc insulation tape cable crimping and hand tools heatshrink hospital saddles cable ties and general cable management products.
Helps determine the proper wire size for an electrical circuit based on the voltage drop and current carrying capacity of an electrical circuit.
Now select the size of cable for load current of 30 2a from table 1 which is 7 1 04 31 amperes it means we can use 7 0 036 cable according table 1.
