Italia vs Svizzera: distribuzione civile TT vs TN — cosa cambia e perché

Italy and Switzerland use two completely different residential electrical distribution systems. In Italy, the TT system; in Switzerland, the TN-C-S system. They use the same basic European standard (HD 60364), but have opposing philosophies on how to manage neutral, earth, and protection devices. In this video, we look at: ⚡ The Italian TT system: independent earthing, mandatory differential ⚡ The Swiss TN system: the PEN conductor, what happens when it breaks ⚡ TN-C, TN-C-S, TN-S: the three variants and why pure TN-C is no longer permitted ⚡ The PEN separation point in the overall picture ⚡ Electromagnetic compatibility: why TN-C disrupts electronics ⚡ How to understand which system you're working with (impedance measurement) ⚡ Periodic checks: why you won't find obsolete systems in Switzerland ⚡ Real advantages and disadvantages of both systems For electricians, students, and anyone working across borders. 📌 Chapters: 0:00 Intro 0:43 The Italian TT System 3:42 The Swiss TN System 5:00 The PEN Problem 5:58 TN-C-S: The Modern Solution 8:22 Practical Comparison 9:18 Controls and Compliance 12:35 Conclusion 👍🏻 LIKE and SHARE! 💬 Let me know in the comments what you think or what topic you'd like to see in future videos. 💡 Support the channel and get access to the benefits! 🎥 Subscribe 👉🏻    / @elisabettavannucchi   🍵 Would you like to offer me a cup of tea? 👉🏻 https://www.buymeacoffee.com/elisabettaK 👋 Hi, I'm Elisabetta!
