Bonding central heating pipes

[Des 56]

Seem to recall reading somewhere that this was not permitted,as it was not possible to confirm that the minimum size of bonding conductor was used....


An nic inspector once berated a firm I worked for because they did just that
I cant remember his gripe, but perhaps there may be problem with the contact area not being sufficient

Just a stab in the dark
It would seem to me that the connection area is only being made where the screw end presses down, and may not be sufficient

I only ever do this if instructed to.
Whan I do it, I link the bands of the earth clamps together by passing the end of the first one through the next and so on.
I then attach the earth conductor to just one of the clamps.

Sorry i'm being a bit thick, So you use the strap as the conductor?

No project I've ever worked on would let you get away with that.
