I have to extend the cable feeding 13A sockets. Is this:

http://wiki.diyfaq.org.uk/index.php?...Cable_crimping

'maintenance free'? Or should I use a junction box. The cable will be
underneath floorboards, routed properly.

And apologies - I'm sure I've seen this raised before - but I can't find
the question or remember the answer.

If the floorboards are liftable, you could arguably use a regular
junction box. However, bearing in mind that people lay carpets and
laminate over the top, I'd use one of these:

Maintenance free, cable clamps and fixing of the box by screws to the
joist - everything you need in one box at a dirt cheap price. I have
used these BTW and they are good.

Crimping is also fine - and maintenance free - but these boxes are a lot
less effort.

Wago terminals in a wago box are also ok... (and quite nice for PITA
places to work in since like crimps you can make each wire connection
individually and then stuff em in the box)

Many thanks all - I'll be getting some of the boxes Tim mentioned.

Zarabanda my friend!!

I would check the details of that junction box, 32A may be the headline figure when used in a standard setting it might be reduced in maintenance free mode. I have used Wagos extensively recently they too are rated at 32A but the leaflet provided points out that used in maintenance free mode their rating should be derated to 20A and quotes some BS number as the standard for compliance which I suspect applies across the board to all such connectors.

Oops! Just realised I replied to a 2014 post. Ce la vie.

The 773-173 connectors are good for 32A in maintenance free mode (they do appear to be the notable exception to the general rule though).

I suppose over here were pretty unlikely to use aluminium cables, but
I'd never heard of their "Alu-Plus" contact paste

At one point aluminium cables were used because copper got rather
expensive. then 15th, 16th & 17th editions of the wiring regs have tables
labelled "Aluminium Conductors". Not in the current (18th) edition
