Issues with installation of EV Charger

[baseborn]

Thanks both so much. I suspect Octopus have made a mess of it as the guy didn’t fill me with much confidence and everything else says TNS. I will investigate further with the DNO and report back

Normally the earth cable is connected to the sheath of the service cable when TNS and is normally done just below where it enters the head.

Not on new stuff. Two of my TNS supplies have split concentric service cables coming up from underground ducts, into service heads exactly like those, and the earth connection is to the side of those service blocks, exactly like it would be for TNC-S. There's a link inside the head that's fitted for TNC-S, but left out for TNS.

DNO says their records don’t state what earthing they provided - which is very helpful! Waiting for them to book in a survey and will try push octopus for a revisit by a different engineer in the meantime. What a faff!

Well it is progress at least.

With so much conflicting info getting the DNO to survey is the right thing. You will get a definitive answer on the earthing arrangements there which will allow you to move forward.

Something strange is going on because Octopus obviously at some point tried to make it TNCS and for some reason started it and then stopped it, they may have actually done it and then took it out, I guess we will never know!

Good luck and please report back it is always great to find out what actually happened as it helps to inform others.
