Moving light pendant - extending the cable question

[gcltd]

Hi, I'm moving 2 bedroom light pendants to the centre of the rooms, could someone please advise what connection/junction box I need to use when I extend the existing cable?

Many Thanks

The best option is always to entirely replace cables with longer ones, rather than extend.

You should either make sure it's accessible in which case you can use a normal screw terminal in a round junction box enclosure, as seen in b&q etc. Also make sure the cables are clipped down and it's secure.

Alternatively if it won't be accessible then you need a maintenance free connection which probably best to use wago push fit in a proper wagobox. I think you can get them at screw fix and other places.

If you're handy with crimpers or soldering you can do that and heat shrink, but not everyone agrees with crimping.

Or as above, if the cable is easy to replace then just do that.

Seriously?

What if one of the cables that needs extending originates in the CU on a different floor and at the far end of the building?

Unlikely in this case.

How do you know, do you have some knowledge of this house? Nothing wrong with extending cables.

It's likely that your light is fed from a ceiling rose so it might be worth taking pictures and marking cables before you move or dismantle what's there. Chances are if you are moving the pendants to the centre from there existing position by a window? Then they will probably need shortening if you're lucky.

Introduces an extra connection, hence possible failure.
