BEAMA Guide to RCD Protection of EV Charging Installations
This guide provides information on the selection and application of Residual Current Devices (RCDs) for the protection of electric vehicle (EV) charging installations. It covers the requirements for RCDs, the effects of DC fault currents on RCDs, and the use of RDC-DDs, RDC-MDs, and RDC-PDs in EV charging systems.
The document details specific regulations from BS 7671, including the need for Type A, Type B, or Type F RCDs, and explains how to handle DC fault currents exceeding 6 mA. It further classifies Residual Direct Current Detecting Devices (RDC-DDs) into RDC-MDs and RDC-PDs, describing their construction and application in Mode 3 charging scenarios.
Covers: Introduction · Abbreviations and Definitions · RCD selection · Effects of DC fault currents on RCDs · RDC-DDs · RDC-MDs
