shortly to be relocating a consumer unit from a cupboard (which will become a WC) to a small constructed wooden cabinet outside said cupboard.
Can I use 18mm ply as the backplane for the consumer unit to mount onto? I'll need to extend the circuits to the new location - so what's the neatest way? junction box for each circuit?
thanks,
Jim
Crimps, but practice first. Al
Not a problem for a modern consumer unit. I wouldn't fit an old fuse box, though.
No. Use appropriate crimps applied using a decent ratchet style crimper.

Is there any problem with mounting a CU directly onto masonry?
No, but it makes it harder to attach and route cables.
Christian.
Don't forget that CUs have knockouts into which grommets can be inserted.....

I don't think I've seen this kind of thing for domestic wiring - can you point me in the right direction? brand name, type of crimp connector etc?
thanks,
Jim
Are these the same type of crimps that you use for automotive wiring? I found a ratchet type draper crimper and various crimp connectors over at tooled-up.com - is this the type of thing you mean?
Once you've crimped the conductors together, do you just bind the whole thing up in insulating tape?
Is this good enough for ring main circuits, shower circuits etc?
Thanks,
Jim
Or use heat-shrink sleeving, if you don't want the whole lot to turn into a big gooey mess at some point in the future.
Only if the crimps are appropriately rated for current. I would never use crimps on a shower circuit, for example.

They're nothing special. Just insulated butt crimps with a standard ratchet crimper. Available from almost any electrical wholesaler or DIY shop.
Christian.
OK. Thanks to all replies. A big help.
Jim
Stating the obvious maybe, but you still need to additionally insulate or house the crimped joints in an enclosure.

Yes, I should probably have given the codes for heatshrink tubing, too...
Christian.
Could you? I'm running out and my local store has stopped selling it. I need stuff to cover 2.5mm2 T+E.
Thanks, Al

But any electrical wholesaler worthy of the name will have crimps, the crimp tool and heat shrink sleeving. Probably not a shed, though.
If you're not sure about this, give your area and perhaps someone can recommend a specific dealer.
