13amp outdoor ev charging socket

[robv]

Hi, so I would like to have fitted the above for a future EV. I know the charging speed ~10amp is slow but not an issue to me. Anyway the reason I'm posting this is because Im looped onto my neighbour and can't have a 7kw EV charger fitted, the garden would be dug up and it's simply not an option. So as an alternative would I safely be able to charge (slowly) using an outdoor 13amp 3 pin ev socket wired to the CU with 4mmt+e cable with a 16amp rcbo breaker in the CU. I'm deliberately thinking of the thicker cable as it shouldn't get warm as opposed to 2,5mm. Can anyone endorse this setup or give any feedback before I go ahead with getting it fitted. Thank you.

You can fit a 13A socket but it must be certified for EV use. This mode of charging should only really be used as a temporary measure and new vehicles are phasing this out.

Taking a pragmatic approach to this while you are saying you don't want your garden dug up what if your looped neighbour decides they want / need a 7Kw EV chargepoint
From the information you give in your post I'm assuming this is what ENWL have told you following an ENA application and a subsequent onsite survey or are you just making an assumption
While your 13A socket idea would work you could also fit an EV chargepoint limited to a 13A charge output without the unlooping work

This needs correct design to ascertain the cable size and if you are in England or Wales notifying to Building Control.

A more sensible solution would be a proper EV charge point using 16A

Thanks for that link. A bit cheaper than a couple iv seen that have been £60 plus!

Are you supplied from the cable going first to your neighbour or is you neighbour supplied from your cable?

How well do you get on with your neighbour?

Does your neighbour have any future plans for EV charging?

Are there any merits with doing a supply cable upgrade as a "joint project" with your neighbour, sharing the costs, to give both of you, long term benefits on your respective supply capacities?

Looped supplies suggests your properties are quite old and you would both probably benefit from upgraded incoming supply cables?

As has been said this work is NOT a DIY project..
It needs correct design, installation, testing, certification and Part-P building regulations notification.

There are no costs to share from the DNO for the supply cable upgrade

I put an ENA application for a customer a couple of months back and following a recent survey to unloop the supply the DNO is saying they will have to rewire the street as well as the unloop to allow my customers EV chargepoint installation to continue, which is due to happen in the next 2 - 3 months and my customer was told to encourage his neighbours to get ENA applications in if they are considering an EV in the next few years

this is the socket I'm thinking of having installed, I will be getting it done professionally and not DIY. As you can see it has it's own rcbo integrated into it. With this in mind would I still need an rcbo breaker at the CU that supplies this outlet or would a just a MCB be ok?

We are supplied from our neighbour so it would involve our garden to be dug up unfortunately. The dno (electricity north west) has said they could do it for free but it's just all the upheaval and mess. I'm just trying to find a way round this safely without unlooping. Btw I would never dream of just plugging it into a normal household socket that's why I want to get this setup installed

Our main incoming fuse for both properties is 100amps. This should be adequate for the trickle charging socket? We don't have electric showers or anything so load wouldn't be an issue

I you are feeling keen, dig the trench yourself, it's a lot less messy than contractors

You may only be delaying the inevitable should your neighbour decide to install an EV chargepoint

Our main incoming fuse for both properties is 100amps.

While the service head has a label on it indicating 100A it could well be fitted with a 60A or 80A fuse

I am guessing that you are assuming they are 100A because the cut-out fuse holder looks something like this?

The 100Amp bit is not the actual rating of the cartridge fuse inside....
(Consider it an indication of the max possible rating that could go into that fuse holder)

Ours says 100A on the outside..
But when our meter was replaced many years ago, our DNO was also doing routine update checking all fuse ratings, and where applicable downrating them to 80A!

And it is not uncommon for an older lower capacity cut-out to have been updated with a standard newer cut-out housing capable of 100A, but actually fitted with a 60A fuse.

If I were a betting man I would be putting my money on neither of your properties actually having 100A fuses!
More likely 2x 60A fuses on a looped supply.??

I never realised that splitting a looped supply was a free service...
But if that is the case then it is a no-brainer...
Just get it done.. And save yourself from loads of potential hassle further down the line!!

Our supply is not looped.. but it is old.. property built in 1925..
Quite a few years ago the old cable under our drive suffered a significant failure knocking all of our power off...

It took a few hours of digging replace and repair before we were fully back up an running...

Most looped domestic supplies are also quite a few years old!
So lets just hope the old cable supplying your neighbours property doesn't suffer a similar problem that our old non-looped cable did! and causes both you and your neighbour a loss of power.

All electrical cables do deteriorate over time and usage...
So just because something has worked ok for the past few years,
There is no guarantee it will continue working without failure!

Screwfix are not the cheapest supplier of these items!
