SWA to Switch?

[Colin33]

Any suggestions as to how to terminate swa into a switch/fuse neatly? I've run it through a metal box and out to the switch with the switch cover covering the point where the sheath is split but wondering if there's a neater way to do things?

Would you get two 25mm tails though a single gland?

I'm always a bit late...sorry. I'm still on the yellow book ;-)

Yes if you use a big enough gland.

Are you trying to wind me up. April fools was yesterday

I don't think anyone is going to better you on that one...Olaf!

I'm sure the reg for ferrous enclosures was still included in that version. The reg number in the current edition which you should be using is 521.5.1

I'm joking about the book of course, but I have to admit, the last time I looked at one of these books was during my half day 17th update all those years ago

Anyhow, that must be a massive gland to fit two 25mm's through! Surely too big to fit in a 25mm knockout?

That enclosure will happily take a 38mm gland possibly even a 50mm. I would say you would get 2 x 25mm tails into a 32mm.

How ever you you enter the box with your tails if they are exposed they need to be double insulated and restrained in some manner so any external movement on the cable will not act directly on the terminations... can you not terminate into a 25mm metal through box and bush it to the box running the cores straight through and tapping of the box for earth?

 

[Colin33]

I may just opt for the grommet, got plenty of those... Thanks for the suggestion though, I was trying to work with what I already had but it makes for more sense to splash out on one of these for a much neater job! Even better if I can take the tails out of the top of the unit, with the swa entering at the bottom...

Not sure what you mean there... are we talking about the tails here?

32mm stuffers bang on, will let 2 x 25mm tails and a 16mm earth out no problem and iirc on the Wylex 110M's it's a 32mm knock out so jobs a good'un for our clueless OP and is ALOT neater than a grommet

Oi Oi Oi ! Clueless... thanks cockney reject

 

[Darkwood]

Splashing out!!!... a stuffing gland of the correct size maybe a quid at that, drill a bigger hole if necessary, you sound very defeative tbh .. if it makes the job look more professional then spend a few quid extra ... if its your own house then its not really an issue as long as its functional and safe.

 

[Colin33]

I meant on the switch, not the gland!!
It's not my own house but what stated as a relatively simple layout has got bigger and bigger and I'm running out of space on the wall!! Already have all the sola PV stuff, then a supply to a sauna, and now another to a seperate 'cabin' outside.... it's tricky getting a neat n tidy layout when things are added all the time... a bit like adding another circuit to an already neatly stuffed CU ;-)

your welcome mate

like darkwoods already said a 32mm stuffer ain't a lot of money and if a Wylex units too pricey for you CEF do a metal clad range for not a lot of money and a 32mm hole saws not going to break the bank either, why be defeated by something so simple?
