this is a favour for someone else and I want to try and keep costs

Any recommendations for cheaper IP66/67 boxes that will be robust and
durable enough, and which will be a good deal less that £60 in total?

I should add that this cable is to run along a garden border about a
foot off the ground.



Anyway, after a few days' use of the old stuff, it would have
needed replacement just as much as new-bought stuff would.

Yup, I quite like those...

For a "straight through" join, the metal conduit boxes make gland to
gland earth continuity a bit easier though, and are very robust.

(he will need three sets of glands as well - probably 20s for 2 core
SWA, or 20 for 3 core).



3 core 4mm uses a 20s.

Yup could be - I have seen conflicting info on that. Our table :

http://wiki.diyfaq.org.uk/index.php/...WA#Gland_Sizes

has it as 20 for three core, but many manufacturers sites say 20s will
still fit.

We probably should update our table.


And end up as accurate as the cleat size recommendations that
manufacturers use?

The only use for black insulation tape is to pack out the SWA when the
cleats are too big.
