Hi all,
I'm finally running the cable to the garage.
What is the spacing for SWA cleats clipped to the side of a wall ?
SWA is 10mm x 3 core.

Thanks,
Simon.

AIUI, in a PME area, you must not export the PME Earth
but provide your own earth rod.

Yes. We are TN-S, good old fashioned lead sheath.
We also have lead water pipe coming in.
We love lead !
(No lead paint any more though)

You wouldn't want to be ingesting any of that...

You can export your PME earth - but you must also make sure the
equipotential zone is exported with it.

So that means its only sensible to export it to places where its
possible to maintain the equipotential zone. (So you can't export it to
a place that has easy access to an independent earth like a greenhouse).

Also the earth in the submain will also need to double up as a main
bonding conductor, so the shield of the SWA alone will not usually have
a large enough "copper equivalent" cross section to act as a protective
earth and a main equipotential bond.

Cheers,

John.

You generally treat PME and TN-S as the same things these days.

It might be a separate earth into the house but it could be connected as
PME in the street.

Hmm. So how "far away" does the earth/neutral connection have to be for it to not be PME ?

How many cleats have you got?

Spacing = Distance / (Cleats-1)

With one clip that gives divide by zero...

Should that not be?:

Spacing = Distance / (Cleats+1)

That puts your single clip in the middle!

I was working on a clip at each end ...

IF Cleats>=2
THEN Spacing=Distance/(Cleats-1)

SWA is 10mm x 3 core.
Every foot or so... you could probably go a bit wider on 10mm^2 since
its pretty stiff.

It is 400mm, however two brick spaces will be fine.

Another option is to run the cable in plastic conduit so that
it is supported along its entire length and so will not sag.

That's not clipped-direct. Would it get hot if carrying a lot of
raisons and exposed to sunlight ?.

I wonder what the saddle spacing of the conduit would be?

Someone put some conduit up near here and they used a clip about every
1.2m. it sags about 100mm in the middle.
Supposed to have been an electrician but I somehow doubt it.
