And now I have learned that soldered connections are prohibited by the code in most of the EU. It is considered dangerous. For an explanation, I had to ask chatgpt. I asked again (the original answer is gone from my browser), the answer is slightly different: Q: Could you explain why the electric code in the EU prohibits soldered connections? English, please. Yes, absolutely. In the **EU**, soldered connections are **not completely prohibited**, but their use is **restricted or discouraged** in **certain permanent wiring installations**, especially in fixed electrical systems like household or commercial building wiring. Here’s **why**: --- ### 🔧 **Soldered Connections Can Be Mechanically Weak** * **Solder alone doesn't provide strong mechanical strength.** If a wire is only soldered (without a mechanical connector like a terminal block or screw clamp), the connection can **break or loosen** under stress, vibration, or heat cycles. * **Solder can deform over time.** It softens at relatively low temperatures. If the connection heats up (even slightly under normal use), the solder may **creep** or **change shape**, causing a loose or unreliable connection. --- ### 🔥 **Fire Safety & Overheating Risks** * A **loose connection** increases electrical resistance, which can generate heat. * Over time, this can cause **overheating**, **insulation damage**, or even **fire**. * Because soldered joints are more likely to loosen, they are **considered less safe** in fixed installations where ongoing maintenance isn’t practical. --- ### 📘 **EU Wiring Standards – Specifically EN 60364 / IEC 60364** * These are the European and international standards for electrical installations. * They require that connections be **"durable, mechanically secure, and protected against stress."** * **Screw terminals, spring clamps, crimp connectors,** and other mechanical fasteners are **approved methods** because they ensure strong, reliable connections. --- ### ✔️ OK in Electronics, Not in Fixed Wiring * **Soldering is perfectly fine** and standard in **circuit boards**, electronics, and small appliances. * But in **fixed electrical wiring** (e.g. behind your walls), **soldering is discouraged or banned** as the sole method of connection. --- ### ✅ Bottom Line: > The EU restricts soldered connections in permanent wiring **because they are not mechanically reliable on their own**. Safe connections must be both **electrically sound** and **mechanically strong**, which solder alone doesn’t guarantee. Let me know if you'd like references from the standards or help with specific national codes like the UK’s BS 7671 (IET Wiring Regulations). -- Cheers, Carlos.
