EEBADS (the actual insulation of such safety measure)

I know we bond pipe work with earth clamps and 4.0mm earth cable. But does anyone know why some people coil up the earth conductor, making it look like a spring? Instead of just putting a small length from A to B without making it go round and round an imaginary loo roll?

Back in the 16th days I always did it with pigtails because it looked nice.

No other consideration just pride in my own work.


Probably was a waste of cable but I wasn't paying for it, as for inductance loops well where is the induced current going to go? down to earth maybe.

I think there is a huge difference between a couple of 360's to give an extra few inches, and something that looks like a garage forecourt airline

Like this, you mean?!

lol that just looks ****

I used to work a lot in commercial kitchens and benches etc would be bonded in the coiled way, allowing for the bench to be pulled out 500mm for the deep clean without having to disconnect the bond, it was in the spec for this to be done.

Well pop over to the brand-spanking newly built QNCC in Doha, and you will find MILE after MILE after MILE of such fine cable wasteage. My theory is that it's been done deliberately so that in the event of a massive fault to earth, the whole place will just become one big electromagnet long enough to drag even more dollar coins into the place.

I will be there in September, I will keep a look out for it

Yhea anything over 2 - 4 inches of pigtail just looks silly.

The kitchen bench scenario makes sense.
