If you’ve never installed a Surge Protection Device (SPD) before, don’t worry — it’s simpler than you might think. Here’s a step-by-step guide to get you started:
-
Pick the Right SPD: Type 2 SPDs are the standard for EV charger installs. They handle typical surges effectively.
-
Find the Best Spot: Install the SPD close to the main distribution board that feeds your EV charger. The closer, the better.
-
Wiring: Connect the SPD between the line (live) and earth conductors, following manufacturer instructions exactly. This ensures proper surge diversion.
-
Secure the Device: Mount it firmly to avoid movement or vibration.
-
Test Everything: After installation, test your setup to confirm everything is working as expected and document for compliance.
At Eco Harmony, we provide SPD kits with clear instructions and everything you need to make the job smooth: Shop Surge Protection Kits.
In short:
-
Choose the right SPD type.
-
Install it close to your distribution board.

Follow wiring instructions carefully.
