Hi,


I need some advice on this product. The instructions that came with it
don't give any wiring examples.


It's not sold as a DIY product, so you'd be expected to know how to wire
it.

I got this because I want to join two pieces of 2.5mm T&E outside to
form a single run (the cable is encased in 20mm plastic pipe). There
are reasons I cannot run a single length of cable point to point. Can
anyone help with these questions?


1. Firstly there are 4 terminals on each set of terminal block, I
presume I just don't use the 4th one, as the cable only has 3 wires?


Correct. The fourth terminal is for where it's being used for the junction
point of a lighting switch, etc.

2. Does it matter as to which of the 4 terminals on a block the live,
neutral and earth connect to?


No. It would be marked if it did.

3. I presume the incoming T&E cable goes to any one of the 4 blocks,
the outgoing cables go from another. Is it simply a case of using small
lengths of cable inside the junction box to join the corresponding
terminals as well? If not, what is the proper way to achieve what I
want, preferably using the junction box and knowing I can't have one
single length of cable and the join is outside.


Each of the four terminal blocks consists of a strip of brass with 4 holes
in it for the cables and 4 screws which go into the top of those holes,
then moulded into the plastic. So each of the four blocks is internally
connected to itself, but not the others.

Thanks,


James
