Ev point on a new build

[Peter1891]

Morning chaps
I’m starting two new builds next week and they’ve added a vehicle Charging point to each house,
Do I feed this via a 6mm t&e from the main cu or have a separate cu for it on an A type RCD?
I’ve not done my Ev course yet as it’s been cancelled 3 times due to corona and plus there isn’t a lot of call for it where I am at present, I think someone else who is olEv registered will be second fixing due to the builder getting a grant which I can’t offer.
I just want to know how best to tackle first fix.
thanks chaps

I would probably put in a swa cable (6mm 7kW?) on a mcb then the EV installer can put in the correct RCD protection in on their equipment.

Hi thank you, I’m installing an rcbo board so would I run the armoured from the main Cu not a separate one on a 40amp mcb rather than an rcbo?

Just a mcb not a RCBO, I'm sure you can swap one.

Yep that’s as I assumed thank you.

I would advise A type a RCBO that isolates both poles and also run a 2 core screened cable for any load monitoring

What does the manufacturers instructions say? the builder probably knows who's Charging point they are going to use.

Type A rcbo to protect the cable from the cu to the Ev point? Surely only an mcb is sufficient isn’t it if I’m using armoured?

I don’t start until next week so I have no idea at this point I just wanted to clarify my knowledge from what I know so far

Some Ev points have fitted RCDs so only a MCB required if in SWA
Some require a separate Type A RCD fitted and MCB so a RCBO at DB is way forward
If in twin and earth then RCD protection will be required if buried in walls etc

 

[Strima]

You need to know the make and model of the EV unit, also requirements for earth electrode etc.

 

[hasel5]

As above as well

I would advice Btype, but/good luck finding one.

And sit down when you get told the price

And as I said eight posts ago.
