Connector blocks

[antony.adshead]

I'm just in the process of rewiring a floor of the house (Part P? Don't ask) and need to extend a couple of lengths of 2.5mm T&E cable. Is it acceptable under IEE regs to use connector blocks?

If you are rewiring then why do you need to extend it??

[antony.adshead]

We've opened up a couple of walls and need to re-route cable.

Some of the cable is OK, but because we've opened up a couple of walls we need to re-route some cable

and the helpful response is:

If the joint is to be inaccessible (eg. buried in plaster or under a tiled floor) then you should use solder or crimps, otherwise a protected connector block would be acceptable. Btw, insulation tape does count as acceptable protection, it means in a box.

you mean does NOT count I think Fred!

Indeed, just testing :-D Thanks,

In which case (if classed as 'accessible') it would simply be easier and cheaper to use one of those circular bakelike jobbies ?

[Dave Plowman (News)]

Yes. Called Junction Boxes. It's what they're for.

Yes, just sounded like the OP had an attraction to choccy block so I didn't want to spoil his party. I'm very wary of the circular JBs you mention as I have found many of them to be fragile and poorly made; for anything high current like a ring main I'd rather use a quality choccy block in a box. I've used rectangular 30A JBs from MK and they're fine but cost a fortune.

Fair enough :-)

Yes, I've had the brass inserts crack the bakelite if you over(but not by much) tighten the screw. I used some for both TLC and Wilkinsons recently without mishap however.
