How does BS7671 amendment 1 change the way we install EV chargers?

Electric vehicle charger installation has been a challenging issue for the IET wiring regulations and codes of practice. No sooner are earth rods the default option to protect against PEN faults on TNCS supplies, then things change.

No sooner was the ink dry on BS7671 -18th edition and amendment 1 came along. The amendment was prompted by innovation within EV chargers (the unicorn device) and the rapidly growing adoption of electric vehicles.

In this video, Gary Hayers is joined by Dr Chris Horne of Myenergi - and the pioneers of the unicorn device within the Zappi EV charger.
