Current Carrying Capacities of SWA Cable
The Current Carrying Capacity of SWA Cable tables are important for many reasons, both electrical engineers and electricians use this information to size the correct cable before the installation begins.
These tables will give the electrical contractor current rating in Amps for the given cable, as well as cross sectional area for the cable, Overall diameter and approx weight per metre and further technical specifications for a certain types of SWA Cable. In this case, the specifications are listed by the Core count. Below are links to pages which will display a table of technical specifications for SWA Cable dependent on cores 2, 3, 4, 5.
Why Size Your Armoured Cable
It is important to size your Armoured Cable correctly to provide a safe electrical installation. A wrongly sized cable can supply a voltage with more than the permissible 3% and 5% volt drop. Another major disadvantage can be heat produced within a cable that is overloaded giving the risk or electrical fire.
The following sizes Armoured cable are available in the UK
1.5mm – 2.5mm – 4mm – 6mm – 10mm – 16mm – 25mm – 35mm – 50mm – 70mm – 95mm – 120mm – 150mm – 240mm – 300mm – 400mm – 630mm – 800mm – 1000mm

After you have used the tables provided to size your cables, you may want to try our SWA cable calculator its a free tool we provide to assist our trade and DIY project engineers in choosing the correct size cables for the job. All you will need is the length of the cable and the current in Amps you plan to use, then select volt drop as a percentage 3% or 5%. and finally whether it is single phase or three phase. Good luck.
