A shocking revelation has emerged from New Zealand's engineering industry, warning of a potential electrocution hazard due to recent changes in electrical safety rules. The country's leading engineering group has joined forces with electrical inspectors to sound the alarm, highlighting a new 'lethal' risk that could impact households and businesses alike.
The controversial change lifts a ban on inserting switches, circuits, or fuses into mains power earthing systems. This move has sparked concern, as it removes critical protections for the primary safety wire in New Zealand's electrical installations.
And here's where it gets controversial... The electrical inspectors association has taken a bold stand, releasing a Youtube video that accuses Worksafe, the regulatory body, of being in 'cover-up mode' after their attempts to reverse the change were unsuccessful. Worksafe acknowledges the concerns but maintains that guidance for electrical workers will be released soon.
Engineering New Zealand has also voiced its worries, stating that the change was sudden and concerning. They argue that the switch in conductors can create hazardous touch voltages, even without faults in the network or installation.
Dr. Richard Templer, CEO of Engineering New Zealand, shared his surprise at the decision, stating that all electrical engineers and technicians he consulted advised against it. He added, "It's surprising that it proceeded in this manner, especially without a full understanding of the thinking behind it."
The letter from Engineering New Zealand highlights that other comparable countries do not allow such a change, and Australia, for instance, has retained these protections.
Master Electricians has also written to the Ministry of Business, Innovation, and Employment, emphasizing that modeling shows a significant risk of fatal electric shock from household appliances and exposed metalwork due to the switch in the earth.
But here's the part most people miss... Despite the concerns, Worksafe plans to meet with Engineering New Zealand and invite feedback on further technical information. They aim to publish interim guidance for electrical workers this week.
The inspectors' association, however, has lost confidence in Worksafe and Energy Safety, believing that the legislation and safety regulation changes were not properly peer-reviewed.
In its defense, Worksafe had previously stated that the change was necessary to enable safer electric vehicle charging and support future technologies and disaster resilience. But Engineering New Zealand argues that there is no evidence to support this need.
The association's Youtube video claims that no competent person would make such a change, and that Worksafe's response has been inadequate, even threatening electrical workers with prosecution for compliant but unsafe work due to the regulatory changes.
The lack of consultation and guidance from authorities has been a recurring theme, with all parties involved criticizing the process. Master Electricians suggests that the technical advice relied upon was extremely narrow, possibly influenced by someone with a gas background rather than an electrical expert.
Worksafe, in its statement, refers to upcoming information for electrical workers, outlining the restrictions in place to prevent switching. However, the association is challenging the delay in responding to their Official Information Act request, which sought details on the experts consulted by Worksafe.
The criticism and concerns have been building for five weeks, with the association pushing for an independent review of the advice given on the regulatory amendment. While Worksafe has agreed to set up a review next year, the association believes this is too slow, given the potential life-threatening nature of the rule change.
So, what do you think? Is this a necessary change to support future technologies, or a hazardous step backward in electrical safety? We'd love to hear your thoughts in the comments below!
