Hi all
We have just been to look at a fairly new outside lighting install which is experience nuisance tripping. The installation is actually to a v good standard, but its fairly large, so i though i'd try and do some research before we spend hours pulling it apart. All joints to light fittings are done with surface wiska boxes which are above the ground and the supplies are in swa with external glands. However the fittings are connected using hi tuff cable. In some areas of the install ie around the patio, in walls and bedding, this high tuff is in the ground. Is this cable very permeable? With a little inspection, there doesnt seem to be much moisture in the fittings etc and its separated across a few circuits, but if there is a problem with this cable, it would make sense. Has anyone experienced this before. I have been caught out with using flex in ducts before (ducts filled with water and permeated the flex), so we started using water proof flex used in fountains etc.
Any thought appreciated.
thanks
