Advice on new home EV charge point install.

[Oldfriend]

Hi all,































































New ill ( not used yet) of 7.5kw EV charge point.



















New house consumer unit fitted 6months ago and fitted with 16mm tails as the main fuse was 80amp.



Electric company then come to visit to see if the installation is OK for an EV charge point.



They stay yes it is, but the main fuse is changed up to a 100amp. Seems odd to me!



Then the guy comes to fit a new small consumer unit that has surge protection and a double pole B40 circuit breaker.



They use 10mm tails to supply this unit connected just after the meter. (NOT from the house consumer unit). Just after the 100amp fuse.



The sticker on the side of their newly fitted consumer unit says there is an rcd inside that needs tested monthly, BUT there is no rcd here.

Is this the correct installation.

A few things seem very wrong to me.

Any constructive advice would be good.

Not the best location for the main intake fuse and consumer unit.

If the cable is armoured, and the armouring earthed, then I'm not seeing any issue - provided it is suitably protected form overload by that 40A MCB.































































I can see that they have not used a normal armoured gland at either end so I'm assuming the armour is earthed inside the consumer unit and inside the charger. Without taking the small consumer unit front off, w

ch would mean pulling the mai n fuse first,



















































They have not used normal armoured glands at either end so I'm assuming the cable is earthed inside the consumer unit and inside the charger. The only way to tell would be to take the front off the small consumer unit but that would mean pulling the main fuse and breaking the seal, so I probably won't do that.

Very true, but not a lot can be done about that now. They did ask about relocating it a few years but got a huge price for doing it, so did not go ahead. None of the guys involved in this latest EV project have even mentioned the location as not ideal.
