The little black box is a fuse for the time clock and the clock is earthed as its a class 1 piece of equipment. Its an old economy 7 arrangement

Could it be a TT with the cable going down to a earth plate or a mat

It could be just a stripped piece of g/y going into the ground. We used to do that on the campsites for TT systems. Should be a min 25mm tho

Another possibility is that it is a TT.

And the water mains is connected to next door.

And its bonded.

And they have TNC-S
