Hi all

i'm still doing my 2330 courses and am being instructed how to wire lighting circuits using a main feed and a strapper down to the switches. We have to told that junction boxes are bad practice as they restrict accessability which makes perfect sense.

I recently had a look at a family members house which has just been re-wired and found that juntion boxes had been used. Is this poor standards to save money on cable or the normal.

cheers everyone

do u mean the JB's were used in the 3 plate lighting connection or someone cut a cable to short and extended it?

its a fairly old house that was re-wired all though. From what i could see junction boxes where used as in the three plate lighting connection.

hi
if the light fittings are not ,ceiling roses ,then "spiders" would be a neater and easyer way of doing it;)

Quite glad someone brought this up. I'm two thirds through my 2330 also, and have worked for several different companies gaining experience on site.

About half have told me that absolutely under no circumstances should a junction box be used even if it means pulling out and reinstalling an entire run of cable that has been cut too short, and the other half have said it's fine to use jb's pretty much wherever it seems the most convenient thing to do.

I'm still quite a bit confused by this! :)

In my opinion using a junction box ,to extend a bit of cable is just lazy and bad practice ,using one to connect to a light fitting thats not a 3 plate fitting ,i think its preferable to using connector block pushed up into the ceiling
junction boxes have provided a solution for electricians for a very long time ,some folks just want to change everything.i will continue to use the good old spider as long as they make them ,but only as a solution not a matter of course
