How Deep to Bury a Cable? You’re Probably Wrong!🤔

How deep should you really bury electrical ducting? 🛠️ It’s one of those questions everyone thinks they know the answer to… until it’s time to grab a spade and actually do the job. In this video, we dig into (literally) the proper way to install underground cable ducting - layer by layer. From setting the trench depth for water pipes at 750mm, to choosing between N750 vs N450 duct, we show you exactly what goes where - and why it matters. ⚠️ We also raise the big question: Do you really need Steel Wire Armoured (SWA) cable inside ducting? Or is something like H07RN-F perfectly suitable when installed correctly? Join the debate in the comments. We’ll cover: • Correct trench depths • Duct types and when to use each • The reason we add warning tape 150 - 300mm above the duct • Backfill layers and separation 💬 Think we went too deep - or not deep enough?
