How should a new EV charger be connected (Ed.)

[SUNRAY]

What would you suggest ?

If I had to find such a route I'd be looking above the ceiling or if it's a suspended floor.

Personally I'd go for the very mormal method of picking up at the meter box.

Despite what others say, CU's IP rated for outdoor use do exist from very reputable manufacturers and many many thousands of them are in use for the purpose.

I quite agree but often you don’t want a labelled CU on the front of your house

Probably no more ugly than the EV point.
Or do a decent job and add an enclosure, such as a meter box to match the existing to take the CU and EV point.

What do you mean by "a labelled CU"?

Are you saying manufacturers lie?

The enclosure will be suitable but the devices in it will not be.

The devices in it will need to be pollution degree 3 or above to be used in an outdoor enclosure.
Those made for consumer units are not.

While such things do exist, they are made to BSEN60947-2, and they are also intended for use by what is defined in BS7671 as 'skilled persons' which is entirely out of the scope of a domestic installation.

I must admit that "pollution degree 3" is a new one on me, so I've had to 'look it up' From what I can see, it appears to relates to (amongst other things) "electrical equipment ion unheated rooms". Is that correct?

Does that mean that all the CUs and switchgear and, indeed,electrical accessories in general in garages etc. (and sometimes other outhouses) are "unacceptable"?

Thank you.
And just to mention I have looked at a number of reputable manufacturers documentation/publicity material and AFAICS they seem to indicate 'standard' CU components are suitable for use in sealed enclosures. I'm sure they would have been reigned in if they are wrong.

The enclosures in question are usually IP65, and I'm not clear as to what type of "pollution" would get into that from outside to have any effect on the devices within the enclosure.

I'd be interested to know whether anyone here has heard of "pollution degree 3"
