Surge protectors play a critical role in electrical safety, but they’re not lightning protection. ⚡️
In this video we dig into what SPDs actually do, what they don’t do, and how to apply them correctly. You’ll learn:
Why SPDs aren’t designed to stop lightning strikes
The different types of surge protective devices and where each belongs
How lead length affects performance and why installation matters 📏
What a surge really is and what causes electrical transients
The role of MOVs and how they clamp overvoltage
Big thanks to ABB for sponsoring this episode. We’ll show you their OVR surge protective devices and how they can protect both service equipment and branch circuits. 🔧
