Victorian Electrical Inspectors

Hi there TTA Electrical Inspectors.
When visually inspecting the labelling for a safety service, AS/NZS 3000:2018 clause 7.2.4.4 (b) says the Main Switch must be labelled with the correct lettering.
Which lettering is correct and which lettering is not compliant according to AS/NZS 3000:2018?

Hi there TTA Electrical Inspectors. Did you know that you can earth a switchboard enclosure with a neutral conductor?

AS/NZS 3000:2018 Clause 5.5.3.5(a) gives us this option as shown on page 298.

Of course, we generally earth metal enclosures with an earthing conductor. But for those studying their electrical Inspectors assessments, you need to be aware that a metallic construction switchboard may have a full-size neutral conductor that is providing the earthing for the switchboard enclosure.
While this is unusual as an everyday practice, this is not a defect for this switchboard.

As in other Australian states, where an earth is not available, a metallic structure can be earthed through a supply neutral conductor.

Can you spot the visual defect TTA Electrical Inspectors?
The left hand DIN rail socket outlet is compliant. The right hand DIN rail socket outlet is not compliant as the neutral conductor is 1.5 mm with a 2.5 mm active conductor.
Wiring Rule 3.5.2 (a)(i)
