Faulty garden spike lights GU10

[Welchyboy1]

This is the third customer i have dealt with in the last year that has had spike lights installed in the garden, then within months they start tripping out rcds

I have always expected water leakage first etc but every time it has been the black flex that supplies the light fitting

it appears the material in the rubber must be absorbing the dampness over time and the IR readings after only 3 or so months are mostly about >0.1Mohms

i installed the lights on one job but the other two were existing works

one job had 12 and 11 were affected

anyone else had this problem? Must be a manufacturing fault of some kind

must be porous rubber. buy your condoms eslewhere.

poor quality fittings im afraid, like the BQ stainless fittings that go rusty after a few weeks well with the salt round here they do lol

Did you mean 'greater' than 0.1Mohms welchy? I wouldn't have thought poor IR readings would start tripping an RCD until they got down to around 0.008Mohms.

Although perhaps they are getting down that low in the rain and have just bumped up abit by the time you test them.

I have had a similar fault - I always try and encourage people to go for Hunza when speccing outside lights, but occasionaly when using cheap ones this is a problem. I usually remove the old cable and rewire with new, decent cable (not the cheap rubbish from China) and haven't had any problems since.
