UK EV Charger Earth Rod

[Ben Murray]

I have completed the 2919 course and was told during this that all chargers would require a TT connection, whether solely for the charger or as part of the full installation. Since completing the course a while ago now, I have discussed with some electricians who say they don't install an earth rod when the property is TN-C-S. What is the general view on this?
Also, the instructions for a Tesla charger says it is constantly monitoring for earth faults and over current, switching the charger off and on accordingly, does this mitigate the requirement for an earth rod? Because it is looking out for a lost neutral with a PME system? My argument is the charger could get confused thinking a main bonding conductor was the new supply to earth but we wouldn't deem this OK.

I will always install to what I believe is correct within the BS and the course I completed, but it gets confusing when you hear differing opinions within the trade. I look forward to hearing your views and welcome any suggested previous posts.

I hope everyone coping as well as they can be during the Covid-19 out break and my thoughts are with those who have lost loved ones and those who are struggling financially. Stay safe.

does look a good charger. Do you have to be trained by the manufacturer to fit them?

guy in video, has no single point of isolation for the installation Now. The earth & blue sleeving used was rather large, no spd? But dont know when it was filmed..

No spd required.......it's only a recommendation to have one and I believe you have to do a course to get a qualification to fit car chargers

You do not have to do a course to fit EV chargers.
Maybe not required for the EV charger, but SPD,S are not a recommendation, they are most certainly required in the 4 indents given in the regulations , apart from the cravat detailed in regulation 443.4 but that does not make them a simple recommendation.

Single dwelling.....recommendation only

No it’s not , you should assess the merit of them being installed, they may not have to be installed but where does it say that they are only recommended?
Unlike the AFDD which clearly states ‘recommended’

Wrong.....recommendation only...client says no then no

Right, I forgot that the client decides on what to install for an electrical installation.
show me where it says recommendation in the regulations?
Specifically the word ‘recommendation’

Watch and learn...you should already know this 10mins in to vid apology accepted

It is a risk assessment with the client and based on your engineering judgment about the justification of installing such as device
It is still not a recommendation why can you not see that?

You obviously have no idea who this man is

Read the regulations book,

Yes I do.
So whatever he says is gospel?
Read the book and understand it for what it says.
Again show me In the book where it says recommendation?

 

[Markyd]

Read the regulations book,

Have done and watched the vid

Well I would say that he knows a lot more than you do

He may do, he may not that’s irrelevant
Obviously your back is up about this so I’ll leave it there.
