Referring to the RIsk Assessment C1 in the COP Electrical Vehicle Charging Equipment Installations which relates to EV charge points on street when TT systems are employed. Hitherto I have completed the assessment relating to similar installations for commercial/industrial settings without too much bother. However, I have noticed that in Step 1 and step 3 of the on street assessment, the wording is different. Step 1 raises caution of an open pen if the EV is within 2.5m of other metalwork connected to other earthing systems even if those earthing systems are themselves TT (or at least that is how I read it). Is this just an issue of contact or proximity with underground conductive parts that might be considered connected to the PME system? Step 3 indicates an unsafe situation if it is possible to touch the EV and “faulty street furniture”
So if I have any item of class 1 street furniture within simultaneous touch of the EV, irrespective of the earthing system to which it is connected, then the implication would seem to be that the installation should not proceed without further measures?
Any clarification would be appreciated.
