In this video, we explore the electrical cable colour codes that were phased out in 2004 and reveal their modern-day equivalents. Understanding both legacy and current wiring colours is essential for electricians, apprentices, and anyone working with older installations.
We highlight the key challenges when interfacing old and new cable colours, explain how to identify them safely, and discuss the requirements set out in BS 7671 (the IET Wiring Regulations).
Whether you’re rewiring a property or carrying out maintenance on existing circuits, this guide will help you stay safe and compliant.
