[QUOTE="SPECIAL LOCATION, post: 123204, member: 250"] Thought #1.... Damp/Moisture in a junction box, bridging 'L' or 'N' to eartrh? e.g. have found J/b's that got packed full of insects, spider web sort of fluff and bits.. provided a path for moisture to bridge the conductors.. Not direct short but proportional to the amount of current flowing and/or the amount of moisture. Thought #2.... Class2 (double Ins) spot lamp fitting, wired in T&E but nowhere for 'E' to be terminated. Earth wire folded back or trapped between cable and cable-clamp in light fitting. Fitting heats up.. Insulation softens bare (floating) earth wire make high res continuity through softened insulation due to pressure from clamp.. Turn lights off.. light cools down... PVC insulation hardens off again.. No continuity whilst cool! Thought #3.... Say stuff this for a game of soldiers I am going down the pub! :D :Blushing GuinnessGuinnessGuinnessGuinnessGuinness ROTFWLROTFWLROTFWL Thought #4 Send Brian?[URL="http://planetsmilies.net"][IMG]http://planetsmilies.net/confused-smiley-17432.gif[/IMG][/URL] I copied this one from Dekes answer sheet! ]:) :coat [/QUOTE]
