Using SWA as circuit protective conductor and how to confirm compliance with the adiabatic equation. In this video I explain where you can find the cross sectional area of the steel wire armour and how to confirm compliance with the equation in table 54.7 of BS7671. • WATCH NEXT: • ➡ Which temperature cable should I use? • Which temperature cable should I use ? • ➡ Electrical calculations How to do the adiabatic equation • Electrical Calculations How to do the... • • This video is part of a series on the subject of Electrical calculations, where I provide some tips based on my experience over more than 20 years in the industry. • I have worked in various sectors in the electrical industry both on the client side and for contractors, I previously worked as an electrical QS for NICEIC approved contractors. • Chapters • 0:00 Introduction • 00:00:24 Can you use the armouring of an SWA cable as CPC? • 00:01:11 What is that size of the SWA? • 00:01:56 Is the size of the armour sufficient? • 00:03:18 Example • 00:04:02 Operating temperature 70 or 90 degrees C?
