Garden lights tripping

[Rauer]

Got called out to someone's garden spike lights tripping out , gu10's metal bodies but there only 2 core flexed! Now the cable is an armoured that is buried and all joints have been resin'd up and no work has gone on in the garden ( apparently) the ir result is 0.14 e-n and l-e ( havent taken the lamps out as of yet!) I was thinking ( I know that thinking is dangerous!!) If one of the neutrals or live has come into contact with the body of the fitting, and the fitting is inserted into the ground ( it's a spike light by the way) could that be the cause? As outside there is also a pond and a hot tub!

find the wet one, theres always a wet one

turn it upside down and watch it drip

Yes as the RCD would see a imbalance and trip out!

Hopefully they are connected to a double pole switch so you can stop the tripping !

 

[Rauer]

Already done that! It all looks ok, I'm just trying to not have to break into that armoured and make off more joints!!!

 

[Rauer]

Only trips under load so I am guessing l-e and I know it's naughty but it trips with the e disconnected hence me thinking traveling back up the water feature and hot tub e!

 

[dcelectrical]

if you split it in half is the pond or hot tub in the 1st half

 

[Rauer]

Yes!! Pond is before the first light and the hot tub is near Ish the 3rd light!

I think anyway! So the homeowner informs me of the cable route!

how is the pond and hot tub wired up..?

 

[Rauer]

Swa, didn't look for a rod by the hot tho. the pond swa I would assume would follow the same route as the lighting swa
