Advice for providing power to a barn conversion

Going back to the question of which end of the SWA should be earthed.
Regulation 542.1.3.3 requires it to be earthed at the installation containing the protective device. In this case the house end of the cable.
Obviously the other option is to connect at both ends.

Hmm. Not considered that. Clients are quite specific about what they do an don't like so the location of the new rod was decided by them. If there'd been any choice in the matter I'd have run some new armour clipped to the underside of a raised step across the path straight into the meter box - but that apparently wasn't acceptable aesthetically.....

Anyhoo.
How far apart would they need to be?

Amazing you're actually listening to the clients, that know absolutely nothing about TT systems, and even less than you seem to know, and allowing them to dictate where the earth electrodes are going to be positioned!!!! Who is the paid professional them or You? .... I'm Gobsmacked!!

Get them as far apart as possible, at least 1.5 to 2 X the buried depth. So what are you going to or thinking about bashing in then, ....3/8'' twiggs (eg 1.2m), or a couple 5/8'' coupled together (eg 2.4m depth)??


Not going to go any further, just going to watch and see what happens on this thread...
