Garden electrics

So many garden electrics cause problems over the years due to poor installation, I've recently refurbished a large garden with multiple garden lights which were tripping the RCD within the property. I was initially called out to solve the problem of the RCD tripping and soon realised that to lighting working again needed quite a bit of work.
This is the first enclosure that I came across in the garden. As you can see it's really rather poorly maintained. It did have a lid on it to be fair, but clearly a lot of moisture and flora and fauna ingress.


First thing to do was to install a new treated post into the ground to site the replacement enclosure.

Then I added additional support to the sides so that the new enclosure was suitably supported.

I then re-terminated all the SWA cabling that was run under the ground and emerged at this point. Previously the installation had no earth continuity on the outer sheath of the cable, you can see here that the use of the brass piranha nuts allow for bonding the earth across the cables.

This was the second enclosure, The following four photos show the before and after.




This was one of the existing junction boxes feeding the individual lights. You can see that the side has been cut away rather than using additional compression glands.

As a result, plenty of woodlice found their way in…

This is another (waterproof) termination that had been installed previously.

And another…

Finally, here is an example of the new junction box installed. You can see that the outer sheath of the SWA has not been earthed. This is because they were all earthed at the larger enclosures. The earth in this case is the third core of the cable itself.
