Week Electrical Training: Why Loose Wires Cause Fires: Why I Pre-Twist.

Why do loose electrical terminations cause so many fires? 🔥 In this deep dive, we break down the actual circuit conditions that lead to dangerous heat build-up inside your walls. A ‘loose connection’ is just the start. What’s really going on involves resistance, voltage drop, and how current behaves under stress. With over 51,000 home fires every year caused by electrical faults and 500 deaths annually, this is not something to take lightly. Whether you’re a homeowner trying to understand the risks or a seasoned electrician, this video helps connect the dots between theory and real-world hazards. We use a real-world circuit with a space heater load to show how resistance in a loose connection can start building serious heat, fast. And what happens as the resistance increases might actually surprise you. 🤯 If you’ve ever wondered why tight terminations and torque settings matter, this is the one video you need to see. We’ll also cover Kirchhoff’s Voltage Law, Ohm’s Law, and the role of fixed vs. variable resistance in circuits to explain how something as small as a loose wire nut or screw can become a dangerous fire-starter. Electricians, are you pre-twisting your wire nuts? Following torque specs? 🛠 These little things matter more than you think. Let’s keep our work safe, clean, and to code. 💪
