Just fixed a ceiling light that had stopped working because one of the earths had come out of the terminal inside the ceiling fitting.
Started me thinking, what if one of the wires had snapped off? There's only just enough cabling to (just) reach the terminals inside the ceiling rose, so what would the (sensible) option be? A chocolate block small enough to fit inside the rose, or would you have to replace the whole cabling from there to where it comes from?
Why are some sparkies so obsessed with leaving so little cable that it's almost under tension when fitted? I put up a ceiling fan in my last house and whatever wire I connected first, it left me with about an inch of gap to put all the other wires in the right holes and screw up the fittings, while balancing a heavy motor on my head. Ridiculous.
