E.L.V. Garden Bollards.

Zoomup
A customer has some underground S.W.A. cable supplying three low level garden lights. The installation is amateurish and now keeps tripping off an R.C.D. He does not want the garden dug up to replace the cable with bad underground joints at the lights. I was wondering if E.L.V. lights could be used at say 12 or 24 Volts via an isolating transformer. Does anyone know of a suitable type of light please? That way the S.W.A could be reused.

    Another option might be to run new ELV cable and abandon the existing.

    It is in my view acceptable to install "hi-tuff" or similar at a very shallow depth if it is only for ELV. Gardening operations might damage the cable, but there would be no electrical danger.


    Cable may be shallow buried under a lawn without any damage to the lawn. Start at one end of the cable route and drive a spade into the soil. Lever the spade sideways without removing any soil. Poke the cable into the slit, and repeat along the run. Tread the displaced soil back into place.


    Not suited for mains voltage, but fine IMHO for ELV at a limited current.


    Yes, I have seen that method used to run audio cables from a large mixing desk to a stage in a lawned park for a two day concert. After the concert, the cables are removed, the turves replaced, and nothing seems different. No damage is apparent.
