ELI Way out of Spec

[GCE]

Thanks for the replies. The comments are as expected. I have bridged the earth / neutral in the main DB and left the sub DB's as TN-S. We will just have to monitor the conductors as I doubt I will get any luck with eskom to replace the earth wire at the transformer although I will try.

I would rather have done it at the meter box if possible at least then i would not have contravened 6.1.6 and if there is a huge surge down neutral earth bond it would happen outside
I say that not knowing cable sizes , positioning etc


SANS10142-1
6.1.6 The neutral conductor shall not be connected direct to earth or to the
earth continuity conductor on the load side of the point of control except as
allowed in 7.16.4.

Noted. I have access to the meter box so I will see whether it can be done there.

I think I jumped the gun there. I cannot join the earth neutral at the kiosk / meter box as there is no earth there. The supply to the kiosk is via aerial bundled conductor and there are only three phases and the neutral which is connected to a dumpy insulator but no earth termination is present.
