I fit quite a lot of 'replace like for like' light fittings. About half of the systems are junction box systems which are easy peasy, the other half are loop-in circuits which can be a right PITA depending on how much cable slack there is.
Every light fitting I come across has a chocky block connector, so the wiring in the loop-in ceiling rose has to be altered. Most light fittings seen to be made in Europe - is the junction box method more standard over there?
After removing the loop-in rose I use a pretty small (2") 5 amp junction box from Maplins which almost always means enlarging the hole in the ceiling to get it through.
In almost every case where the light fitting has been changed in the past I find chocky blocks tucked into the ceiling void, sometimes wrapped in tape, most often not.
Is this use of chocky blocks legal? Am I OTT in my use of 5 amp junction boxes?
