External cabling and the issues with EV.

Dom

Good afternoon, first post so go easy please until I get used to the criticism!

I have for the past few months been working in the domestic sector and planning and designing EV installs. On issue that I come come across often is how we run and install our cables, often the charge point is remote from the property or wanted on a garage 10-15 metres away from the house. 

The main issue being clients do not want their garden or mono block dug up and often catenary wiring is not an option. 

What are the collective thoughts on fixing to a wooden structure such as a fence? 

I draw reference to these regulations but could engineer judgement in day be a factor? 

  • wood preservatives may attack the cable sheath (Regulation Group 522.5 refers)
  • timber fencing is unlikely to be sufficiently rigid (Regulation 522.8.5 refers)
  • the life of timber fencing is likely to be less than that of the cable (Regulation 522.8.1 refers)
  • damage sustained by the fence due to the high winds (may present a risk of electric shock)

I believe collaboration with cable manufacturing companies or even the use of conduit some of the above could be mitigated. 

With Ev and the subsequent demand I feel our industry desperately needs to look at new containment solutions or pursue solutions in fulfilling a clients ask. Safely of course!!! 

Are there any thoughts on this?

Thanks all.

  • Could I ask a question here, if for example we were looking to get a change to the regulations or a new cable route or even a fully new type of  cable containment system what would the process for this be? How would one approach such an ask? Would it be through the IET or the British Standards team etc?   is this something you have ever been involved in? From your responses you have an excellent grasp of regulations and standards.

    To suggest a change to a British Standard, all you need to do is write to the Secretary or Committee Manager, with the proposed change, along with the technical reasoning behind it.

    However, a little knowledge of the approach a standard takes to something is very important.

    For example (tongue-in-cheek), simply saying  "Please permit the use of Skyhook Ducting" wouldn't get very far, because BS 7671 requires Wiring Systems suitable for the installation conditions (relevant external influences) that meet appropriate standards, and are installed taking into account the scope of that wiring systems standard, and of manufacturer's instructions. So in that case, if you want "Skyhook Ducting" the approach is to get that ducting recognised by the relevant product standards for ducting and containment - and BS 7671 may not be the appropriate place to ask for that change.
