Have just installed 20 external LED spike lights that the client has supplied. All wiring is SWA and on an 10a 30ma RCBO. All was well for a while!
Called back at tripping occurring. Found that the Gardener damaged the SWA and a flex from wiska box to fitting. We returned to repair but after a few hours breaker tripped again and so it continued.
Returned after a rethink. Tested fittings and found insulation resistance on the flexes varied from poor to very poor. Stripped on of the flexes so just single insulted cores and resistance excellent as you would expect (seeing as air has a high resistance)
Anyone had anything like this before?
