This one looks perfect :)

As suggested I shall just blank off the spare way and explain to my friend that it is not to be used.

I fit loads of chargers. You don't need to be olev approved to install them. Only if you want to offer the £350 grant do you need that. It's just changed, now we can fit any olev approved charger not just ones we have manufacturers approval for.
If the charger has in built 6maDC protection then you need a Type A RCD or RCBO. Can't recall if the tesla unit has this?
Cheapest source of type a rcbos is ironically Rolec. The new RCBOs seem better than the old blue ones which melted!
Not a fan of the tesla wall charger. Find it quite poorly built and flimsy. Also has a huge hole in bottom you need a 32mm gland for as the supplied plugs are often poorly made and undersized. On the positive you can link 4 together to share load easily.
Best options for easy install is the zappi. It only needs a MCB upfront as all the RCD and DC monitoring and earth monitoring is in the charger and needs no earth rod.

Thanks for all, it was very useful :)
With regards the unit I have linked in my last post, the RCD takes up 4 modules and has 415V written on it. It states single phase but looks like 3 phase. is it single phase and if so why all the extra positions for conductors (as if it was 3 phase)?

Not sure why but some type b RCDs are 3 module. That supplier do good double pole RCDs. Give them a call.

Sorry, I just realised you posted two. For clarity it is the EV Chargers Direct ones I've used (and would recommend) - not the Chint ones.

As @Gavin John Hyde says, host get the customer a Zappi. Much better product. Straight forward top install, Has everything inside for protection and is set up for supplying back to the grid as and when that happens

I agree Richy, however his Tesla car and charger are arriving in a few days and I expect the Tesla charger is part of the deal.

One of my customers was offered a free Tesla charger with his model s as part of some deal with leasing company. he took it and had it fitted via their installers. I then took it down and fitted the Zappi for him, Tesla unit since sold on ebay! he says the 2 dont compare for him as he has solar, and the full myenergi set up to link hot water, ev charging.
