New Zealand's new electrical rule allowing switches in earthing systems risks lethal shocks, alarming inspectors despite safety claims.
A New Zealand rule change allowing switches or fuses in mains earthing systems has alarmed electrical inspectors, who warn it creates a lethal risk of electrocution by potentially energizing household metal fixtures to 230 volts, even during normal operation.
The change, part of 400 updates effective November 13, removes a long-standing ban on manipulating the PEN conductor, contradicting established safety standards and raising concerns about legal ambiguity and inadequate industry consultation.
While WorkSafe says the move supports safer adoption of solar, EV chargers, and disaster resilience, inspectors argue it could lead to fatal shocks despite RCDs and demand its reversal, citing a lack of clear guidance and delayed review.
