PME IET BS:7671:2018 - 722.411.4 TN system (Amendment 1:2020) definition
Protection against electric shock in a single-phase installation is provided by this device which electrically disconnects the vehicle from the live conductors of the supply and from protective earth within 5 s in the event of the utilisation voltage at the charging point, between the line and neutral conductors, being greater than 253 V rms or less than 207 V rms.
This device shall provide isolation and be selected in accordance with Table 537.4. Closing or resetting of the device shall be possible only if the voltage between line and neutral conductors is in the range 207 to 253 V rms.
