Earth spike , through wall?

[grandfortune]

Hi all,

Just fitted a car charger , I need to put an earth spike in but having trouble siting it, the main consumer unit is on the garage wall , directly behind it is earth as the garage is set into the hill if you know what I mean so if I drill through the wall I will hit the mud, is it ok to then hammer the rods in so the rod will be out in horizontal and the rod box fitted on the wall underneath the consumer unit?.

Cheers
Grand

Spinlondon make a comment on usage of earth rod. The earthing arrangement for the installation has not been confirmed on the start of this thread. Suggest you make sure of the earthing arangement first then apply the regs. For simple explanation buy the book above or go to BS7671

Not sure if this post was directed at me, or just mentioned me?
Also not sure whether the Installation Earthing arrangement is relevant.
From what I understand in this instance, the charging point is inside and is not for public use.
Perhaps to save me from having to purchase any literature, someone could explain why an Earth electrode would be necessary in this instance?

The following is a generalism for external EV chargers. The regs should be followed however it’s roughly the following. If it’s TNS and likely to be changed to PME then ev charger should have earth stake. If it’s PME then it must be earth stake. If it’s guaranteed TNS no earth stake. If it’s integral garage EV charger bonded to MET along with anything else in close proximity should have supplementary bonding hope that makes sense.
