I'm just wiring up a shower pull cord in a bathroom and so just for an electric shower
it's that one there so just a couple of tips when you are wiring up a pull cord from new
well firstly it's only about an eight and a half kilowatt shower so I could have gone I could have
got away with um six mil twin earth but I always choose to put in um 10 mil for a shower so in
the future if they're going to upgrade the um the shower to anything bigger you've already got the
capacity in the cable again yes it does cost that little bit more but it's not a massive cost yeah
so when you are prepping the cable okay I always like to leave plenty of flexibility or plenty of
length on the cable as nothing worse than trying to come along and change one of these in the
future and it's stuck up there in the corner to stuck up the pull cords up there and you've
literally got no cable to work with so always just leave okay well like he's a couple of spare cable
so hopefully you'll never have to change it but if you have to then um then at least when you
drop it down you've got all that space to work with secondly when you are prepping the cable
what people sometimes do is they just cut all the wires off at the same length the best tip
I've got is cut the line neutral off first bend them round so they go in to the terminals like so
and that then gives you plenty of spare on the earth or the CPC to come around and tuck
it in nicely to the earth terminal something like that okay rather than
cutting them all off nice and short and then it being a real tight I see that all the time you
see a really bad poor earth connection because the cable's just not long enough so prep it in stages
line neutral first get them done leave a little bit extra length on the CPC and then um and then
and then go from there the next stage I know this is obvious and simple but I've just bent
the cables round okay and then they're just going to tuck up into the terminals nice and easily and
so then hopefully it will look something like this basically it means that you use
you don't use much cable in there it keeps everything nice and neat and tight in here
but if you ever do need to replace this pull cord for a different make or whatever it is you've got
all this extra length that you can use to spare however what I just want to show you on this one
so I've bent the cable round and now you can see because I've bent it round on this little radius
here some of the the strands are now shorter than the others so just to get a pair of side cutters
and cut them flush that way they all go in nice and neat they tuck in nice and neatly and
it's a good job it's a good mechanical connection therefore it'll give a good electrical connection
okay so now the pull cord is all wired up again the CPCs like I said earlier they're a little bit
longer but now they loop around nice and neatly they go into the Earth terminal nice and neat I
haven't twisted the strands up as you can see but the reason for that is because the actual hole on
the earth terminal is quite small so if you twist them both up it would be a struggle with getting
both in so I've laid them in side by side and you can see that I have come through on either
side so there is a really good earth connection one of the problems I often see on these is like
for example on the supply side you might have a good CPC connection on the supplier side and
then on the load side the CPC has then come or the earth has then come disconnected therefore there
is no earth at the shower as you can see that's a really nice nice and neat terminations lastly
the pull cord is now fitted the last thing to do because I've been moving it around quite a lot
just to go over the terminations just double check what they are tight again with these ones I have
double checked them a couple of times um movement of pushing the cable back up can be quite tight
one thing to say yes it is a second hand pull cord it's the same couple
cord that was up there previously but there's nothing wrong with it
