EVCP remote from buildings

Rich Mc

Unusual one, we have a design situation where a number of dwellings are located across a highway from their designated parking bays, no driveways. The highway is owned by the development site (landlord) and I am not sure if it will be adopted in the future. The landlord has asked if we can install EVCP's on each of the designated parking bays supplied from the residents supply for the sole use of the individual residents. Obviously an EVCP per property is not an issue but where they are wanted to locate them is. 

It brings up a host of compliance issues that may have a bearing including Highways act, Regulation 411.3.1.1 exposed conductive parts on the same earthing system, cables below ground across the 3rd party land, TN-C-S earthing systems, whether it would become an 'on street' installation because it is remote from the property, volt drop (approx 40m from the property), is emergency switching required and where, etc, etc. 

The question is, (and I feel this shouldn't even be considered!) but is this possible and if not what regulation(s) or legislation refers? I can't find anything at this stage that would be insurmountable given the will to make it happen but that doesn't sit right. 

I personally would not suggest this is possible for a host of those reasons above but does anyone have any similar experience of this request or can anyone point out any clear regulation or legislation why this would not be possible? 

Thanks in advance

    Conveyancing and land law may also come into it (think about future maintenance, wayleaves, covenants and who gives permission etc.)

    Would suggest this is really "landlord system", and I'm struggling to understand how this might work?

    Thanks Graeme, but from a safety perspective are there any obvious issues?

    Simultaneous contact (as you mentioned)

    Vehicle impact - really, you'd be wanting a more "street furniture" version of the EVSE.

    Different risk profile (public access) - ought to be considered "on street" and many DNOs would not permit open-PEN devices at the moment for on-street.

    Having said that about not using open-PEN, in terms of simultaneous contact (and to avoid the need for all the devices to be protected by open-PEN, given the fact that we have this wrangle with ownership etc, this is an area where you might (if the job really did get going) is it possible to consider all the vehicles sharing a common TT electrode near the charging bays, and thus avoid simultaneous contact?

    I guess it would all need to be agreed on the legal side before you could decide some of these things?

    Are there cable routes available at the correct (NJUG guidance) depths? Might be best to think about ducts rather than burying direct - because it would be easier for maintenance in the future, perhaps avoiding the need for excavation works to replace cables etc.
