Hi All,
a 5A wired fuse. I first took out every light bulb - 10 plus upstairs rooms(would like to know an easier way to fault find), disconnected the the lighting cable from the CU and measured the resistance between Line & Neutral and to Earth and found the readings to be >99.9K ohms in all instances.
Believing that one of the many bulbs had been causing the problem, I re-inserted the Fuse only for it to blow extremly quickly!
I am now baffled (it doesn't take much!), I have no idea why a circuit which appears to be open is causing a "deadish" short.
Appreciate any pearls of wisdom into any aspect of my fault finding procedure please.
Many thanks
Bob N.
