You wouldn't want to be ingesting any of that...
As long as you remember it's *horizontal* distance...
KY ?
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.
One standard hammer's length.
AIUI, in a PME area, you must not export the PME Earth but provide your own earth rod.
I have a sledgehammer and a toffee hammer ...
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)
Simon.
How many cleats have you got?
Spacing = Distance / (Cleats-1)

Well I've managed to find one.
That's easy then. 'In the middle'. ;-)
Cheers, T i m
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.
Every foot or so... you could probably go a bit wider on 10mm^2 since its pretty stiff.
mine is one every brick.
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) ELSE Goto [Screwfix]

Manufacturer's recommendation? Was 400mm last time I used 10mm.
END-IF ??
It is 400mm, however two brick spaces will be fine.
