Bonding

I'm doing a commercial build at the moment and have about a 20M run to the water stopcock and 30M to the gas.... That's direct if I can, not the silly round about route of the submains..

All me books are downstairs in the van, but I was thinking about running a 16mm just to be safe.

 

[Colin Integrale]

It's a TN-CS by the way...

10mm would work out at about 0.06 Ohms at 30 Metres, just on the borderline!

30 meters of 10mm = 0.0549

Oh, just seen the TN-C-S type!

You have to size on the DNO neutral CSA, not your 'tails'

16mm will cover you for a DNO neutral of up to 50mm

30 meters of 10mm = 0.0549

And to 2 more decimal places!

And to 2 more decimal places!

Calculator says 0.0549 are you going to argue with that as well as spurs on 2.5mm cable lol

Also how often do people ask or look to see what the C.S.A of the DNO's Neutral is ?

 

[IQ Electrical]

Lol, I never argue when the other guy's right!

I know what you mean about the suppliers neutral but them's the rules!

 

[Colin Integrale]

Cheers chaps.
