When is supplementary bonding ommited?

[tomodo]

Rewiring a house and moving db to utility room which is located under bathroom, system is a tns , i know if all circuits are on a rcd then supplementary bonding is not required, but i am running a swa around 6 metres in length from the meter box to the db this is not on a rcd... do i now require bonding or install a 100ma rcd on swa??

i know if all circuits are on a rcd then supplementary bonding is not required

Actually, that is only ONE of the conditions.

So what else?

 

[Risteard]

It's all in Section 701.

...The Russelites failed predictions are not in there...

 

[tomodo]

All final circuits protected by rcd? Does that include circuits that run under the bathroom or above? But do not enter..

Are you referring (for the swa) to the new reg 701.411.3.3. See; (i) serving the location (ii) passing through zones 1 and/or 2 not serving the location.
