DC Blinding and RCD Coordination on TT EV Charging Systems

On a TT system the RCD is the primary means of achieving automatic disconnection, so smooth DC leakage from DC chargers, which can blind a Type A device, must be coordinated across the whole protection hierarchy.

Simultaneous Contact Risk in Outdoor EV Charging Installations

Outdoor EV charging can place vehicles, chargers and nearby conductive structures within reach of one another, sometimes on different sources or earthing systems. Assessing simultaneous-contact risk, and the touch and step voltages it can create within about 2.5 m, during feasibility and layout design helps identify hazards before the layout is fixed.
