Inverter diagram for one phase on 3 phase installation feeding 2 db’s

[GCE]

Hi

I disagree with the technical director of ECB and welcome him to show me in the reg's where it is stated that all neutrals must be common.

The present code SANS 10142 ed2 and what i see on the Draft ED 3, which is now out but I am yet to receive my hard copy ,shows the neutrals to be split.

The neutrals on the output of the inverter need to be on a separate neutral bar according to Annex P .

I would be interested to hear back as to how he arrived at his statement.

I agree 100% with GCE and the annexure has always been like this in the last edition and the new one.

I have just purchased the 2020 version of SANS 10142
