What would a profesional do? converting a ceiling rose to JB

[PingCrosby]

Hi,

Sorry to be a pain but could i have some proffessional advice.

I am replacing my existing ceiling light with 2 downlights and in the process intended on just converting my ceiling rose to a junction box and hanging the lights of the JB. I then intended on attatching the JB to the floor beams in the ceiling void accessible from screwed floorboards above.

However I am now informed that JBs have to be accessible - what would you as professionals do in this situation? Would you just use crimps or is there any other solution i can consider.

Hopefully my diagram below will explain the situation i am faced with clearer.

I have taken a look at the existing wiring and sadly there is not enough slack in the cable to reach the first downlighter directly, even if i unclipped the cable and routed it directly, the existing cable would not reach. The only way i can see that i can make the existing cable reach is by using crimps/JBs.

I have looked at running complete new cable - but this would be a massive headache as i would have to lift the flooring in half the house - as a last resort i would consider this

Are there any techniques/tips of the trade i can use to avoid this?

Any advice is welcomed.

Thanks

By crimping an extension on to the original loop and sheathing with heat shrink sleeving you would be ok as it is a permanent joint.
The extended lead could then be fed to one of your d/l's and from there a lead taken to your other d/l.

(Sits back and waits to get flamed for this.... )

there is no reg that says a jb has to be accsesable as long as it is fully enclosed and of the correct size

personally i would say that a screwed board under a carpet would be easily accessable, but what happens when suddenly Mrs want a laminate floor? so i would not put a JB under a floor and would loop from one light to the other.

Under any floor anywhere IMO is not accesible.

Have you ever had to try and fault find on a circuit when you know there is a junction box somewhere, but youve got no idea where it is?

It 's under a floor. The board has been screwed down and "joint box below" has been written on it. Then a carpet has been laid on top. Great thats nice and accessible.

Well at least it will be when youve moved the two double wardrobes, one of which collapses, the bed, dressing table, bed side cabinets, book shelf and chest of drawers to get the carpet up and find the joint in the first place

Screwed joints should not be hidden. Lazyness or incompetence are the only two reasons why you would install one.
