The recommended cable sizes are based upon information provided by the user and are intended as a guide only. The calculation is derived from BS7671 Requirements for Electrical Installation, IEE Wiring Regulations, and is based on the voltage drop selected at 230 and 400 volts. In order for us to provide this information as a guide certain assumptions will have been made
It remains the responsibility of the user to ensure all data and assumptions are correct and that any cable used is suitable for its intended purpose.
The current carrying capacity tables for flexible cords in BS7671 do not include options for different installation methods, results have been included for flexible cords for the whole range of installation methods. It remains the responsibility of the user to ascertain where flexible cords are suitable.
We have combined flexible cords into one result for the use of our calculator (to make it more user friendly) please refer to BS7671 for individual tables and any relevant correction factors etc
