is the leading automated solution for electrical contractors, engineers, and designers who need to ensure absolute compliance with the British Standard for electrical installations. In the modern electrical industry, manual cable calculations are not only time-consuming but also carry a high risk of calculation errors. Under-sizing a cable can lead to catastrophic electrical fires and system failures, while over-sizing results in unnecessary material costs and structural installation difficulties. BS 7671 is not merely a book of
The design of electrical installations requires the precise sizing of conductors to ensure safety, efficiency, and longevity. In the United Kingdom, the standard governing these requirements is BS 7671. Historically, cable sizing was a manual process involving reference to appendix tables and iterative calculations—a process prone to human error and time-consuming reiterations. | Feature | Manual Calculation | Spreadsheet (Excel)
