First thing.....what I know about electrics is how to change a light bulb.
Our security lights need changing as they were corroded.
The wiring operates the lights and the PIRs.
That was the seemingly simple bit. Switch power off, attach new lights.....simple.
When the guy touched the earth he got a belt that nearly knocked him off the roof.
After much faffing and head scratching it became apparent that the original installer had only used 2 core plus earth instead of 3 core plus earth so the earth is continually live.
To compound the problem the garage has a stand alone alarm running off the same wiring so 'somewhere' there is a box which steps it down to 12V as it branches off to feed the alarm.
All this was done when the garage was built so this box is hidden above the ceiling somewhere.
So......he now has to run new cables and cut off the old power.
What should have taken maybe an hour is going to take ?? hours PLUS x metres of rubberised external cable.
Its starting to get expensive
