jimeve Posted February 22, 2021 Posted February 22, 2021 G'day, due to the heavy rainfall last night some water got in from our fire wall and short circuit the second floor lights. We have an electrician in now but struggling to find the problem. He checked all the lights and switches but can't find the problem. Water has got in somewhere but can't locate it. I said to him, maybe when it drys out it will be okay. Just made him laugh. 1 1 Link to comment Share on other sites More sharing options...

Keep the power off and use a continuity tester (on any standard voltmeter) and check between wires in the boxes and outlets in the affected area. Look for water or moisture in any walls or on floors. Sorry that's not much help, but that's what I would be doing.... 2 1 1 Link to comment Share on other sites More sharing options...
Kuya John Posted February 22, 2021 Posted February 22, 2021 Hi Jim, sorry for your troubles. The fact it is the second floor circuit it could well dry out, but only till the next time! If no wetness was found at the light points or swiches, I would presume he has checked the fusebox which feeds the upper circuit. Obviously all that and futher checks should be done with the power off. Any appliances wet could trigger the fuse to go. Wish you luck with it mate. 3 Link to comment Share on other sites More sharing options...

Water gets in and travels down the wall. Also found some cracks on the external wall, water might be getting in there too. Needs scaffolding putting up to do the outside and at the highest point is 50 feet not many builders have that. When It was being built they used bamboo tied together, not happy with that. 1 Link to comment Share on other sites More sharing options...

Popular Post Snowy79 Posted February 22, 2021 Popular Post Posted February 22, 2021 Any decent electrician would have a live cable detector that he runs along the wall and follows the circuit until it stops. Taking into consideration that the circuit breaker doesn't keep tripping obviously. If it does then he should be disconecting the wiring at the switches and seeing if the circuit breaker stays on. If it does the short is after that point. 6 1 Link to comment Share on other sites More sharing options...

No, the cracks are on the rendering on the outside, somehow water is getting through to the hollow-blocks and running down the wall. I can see the cracks but my ladders not big enough. 1 Link to comment Share on other sites More sharing options...
Joey G Posted February 22, 2021 Posted February 22, 2021 Yep, it probably will work when it dries. Sometimes when you get a short circuit it will weld a permanent short between the + and the -. If thats happens it will keep shorting till fixed. On the leakage...besides getting to the source causing the electrical problem, you want to seal the leak source to make sure you don't have mold growing between the walls... it may take a lot of water leaking to short the electric... but a smaller amount leaking through could create a pocket of moisture that you can't see, and over time... could cause mold. 3 1 Link to comment Share on other sites More sharing options...

People here will often sell their tools after each job and hope the new boss buys new. 4 Link to comment Share on other sites More sharing options...
