I have just swapped over from an old rose light fitting, to spotlights in my sons bedroom. The Lighting is on a 5 amp fuse (in the electrical cupboard) and the wiring had a loop on the old rose. the new fixture had just live, neutral, and earth. i have fitted the loop into a 5 amp chock block securely, and fitted insulation tape over this block ( lots ) and then pushed it back into the ceiling. i have fitted the new light and it is working fine. The question i am asking, is should i have really fitted a 5 amp junction box into the loft space, to accomodate these loop wires, i can get to them easily enough, or is the block adequate?
