My question is, presumably I would be correct in thinking the 3/8 rods are not worth the time and should...

    two installations, one earth rod

    A customer of mine has two installations (self contained barn coversions) connected to the same earth electrode. Each consumer unit has a 16mm cable connected to the same rod. I cant help thinking this is poor practice, but what regs does it break, if any?

    Earth rod testers

    It's pretty rare that I come across TT installations, but recently been looking at investing in a bit of extra kit so thought I'd take a look at earth rod testers. I'm amazed at how expensive they are! Some of them are extortionate! I don't mind spending money on something I'm going to use...

    earth rod box

    Hi all, does anyone know if there is a earth rod box enclosure that you can basically mount directly on top of a concrete path. Was planning on removing the old twig and using the existing hole to drive some new ones in, rather than risk hitting a service.
