If you want your EV charger installs to last and keep your customers happy, surge protection isn’t optional — it’s essential.
Surges happen when voltage spikes suddenly, usually due to lightning strikes or switching operations on the grid. These surges can damage sensitive EV chargers or shorten their lifespan.
This is why BS7671, the UK wiring regulations, recommend fitting Surge Protection Devices (SPDs) in many situations, especially when installing EV chargers.
SPDs work by detecting voltage spikes and safely diverting the excess energy to earth before it reaches your equipment. This means fewer service calls, less downtime, and more peace of mind.
Eco Harmony stocks a range of high-quality SPDs designed for EV charger installations, helping you stay compliant and protect your customers’ investment. Check them out here: Surge Protection Devices.
To recap:
-
Surges can cause costly damage to EV chargers.
-
BS7671 requires surge protection in many installs.
