Electric car charger installation

[Dazio]

Hello all,

I need to have an electric car charger installed but at the moment I'm puzzled about what my options are.

My garage is at the back of my house (access through a back road) which begs the question, with the electric car charger installed there,do we need to run a cable to the electric board? The fuse board is under the stairs at the front of the house and access is nearly impossible as it would have to run the garden, kitchen (walls have cabinets top and bottom), completely (floor-to-ceiling tiled) bathroom and to the understairs area (where we have a water tank blocking access from bathroom to electrical board). we are talking 20+ metres too.

I have wifi and power in the garage (8 power sockets)

What solution have i got here?
Thank you so much

Vehicle charging requires it's own circuit from the consumer unit, usually 32A or 40A.

What size and type is the cable currently supplying the garage?

I'm not sure about the cable size but i have 2 black cables running through the garden beds to the garage. also have a couple cables that are feeding the garden lights (controlled by app with box junction in the garage fed from an electric cable).

The garage ra also has an electric roller shutter.
From this info can you tell the type of cable? Or there is anywhere i can see it without calling an electrician?
The plan is to gather all the information to assess without asking people to come and see it and potentially waste their time.
Thank you so much

EV charge point installation is complex. There are many makes of charging points, and the installer has to select the one which suits what you need, and to do that they need to be trained specially to install EV charging points.

But in the main the supply will also have control cables so it will not overload the system, and also often it needs special devices to ensure it does not disable existing RCD's and auto disconnects with a PME system on the loss of PEN.

From your description no one could work out if you can even have a charge point never mind how it can be wired.

I agree Eric, i will get a specialist ev electrician to come and see what needs doing. The whole house was rewired about 10 years ago.

I am attaching some pictures of the fuse box and also on the last picture where the water tank ism is in the direction of the garage.

Any further insight is much appreciated.
Thank you

To be honest you are wasting your time.

ANY decent spark will have to visit you to determine what’s what, and yes you may have thoughts but they may be well off the mark.

Garage is a 20A circuit, so not suitable for EV charging.
RCDs are the wrong type as well, and although there is a spare way it can't be used for EV charging in it's current location.

Those RCDs are not the “wrong type”

If inspected would get a C3

They are for EV charging.

Your post suggested they were wrong full stop

Have you got a spare one I could borrow?

I used to respect JW1 ….. and have been wondering if JW2 is actually the same person

Everyone else read the post in the context of the whole thread.
Sure, flameport could have written paragraphs and paragraphs with context and caveats, but if we all did that then we'd all end up like JohnW2, wouldn't we?

Before we all alienate @Dazio eith bickering....

The answer is, yes, whatever happens you'll need to get a cable back to that mains position, whether that be a direct feed to the EVSE, or an uprated garage supply from which it can be supplied. You will also need a separate unit there (either a small board which can accomdate the right type of RCBO*) or a switchfuse to supply an uprated garage supply. The alternative to that would be to upgrade the existing board, but that would be significant extra expense
