Wiring colours for storage heater switch (20 AMP) is reversed

A lot of research went into this switch replacement, and he still got it incorrect, added sellotape, left exposed copper and missed the cord grip.

For the sake of an hours labour, get a sparky in to sort this little out. A sparky could do this in minutes on his way home.

To be fair, the OP selected the correct switch and wired it as found. They checked the UK wiring colours and questioned what would happen if they reversed the wiring. What's wrong with that ? Is that not what this site is about ?

The termination of the wiring is appalling, yes ? So why not tell them how to improve their practical electrical skills buy using side cutters to trim the copper and where the flex grip should be fitted …… it's DIY (y)

Thank everyone. I try not to trim the copper because it will make it shorter. Do you think insulating tape like below any good to replace the sellotape?

He said he didn't want to cut any of the wires because it would make them shorter.

I presumed it is a bit difficult to work with already.

He did, but are you agreeing that to make them shorter would be a problem.

I'm not quite sure what you mean by that but, if the OP would find it difficult, I would probably be inclined to refer him to Lectrician's previous suggestion.

Kind Regards, John
 
Sometimes the wires in the back box are a bit short.


What difference does it make?

He can wrap a bit of s.a.t. round it if he wants.
 
As someone pointed out earlier the flex neutral looks burnt up and does need cutting back as well as fitting the flex into the flex clamp.
The solid cores look doubled over, so shortening them and also doubling them over again, may make them a bit short and harder to connect.
Mk have tunnel terminals and they claim there is no need to double over anyway, so cutting a few mm off should not be a problem.

True, but the pic seems to suggest that there would be no problem in cutting off a few mm of the exposed cores - the terminal screws are even in unusually convenient places!

He can - but neither you nor I (nor many of the others around here) would do it, so does it necessarily make sense for him to be 'advised' to do it?

I also suspect that if the cables were so short that dealing with the terminations were a problem, that wrapping SAT around the cores might also be a bit of a mission!

You can remove the switch and put it on.



Come on; is it slow tonight?
 
The wires in the back box are a bit short, if I trim it. It might be difficult for me to work on it in the future:cry:
