For the service that we offer see our electrical safety testing page.
This page focusses on plug in appliances rather than electrical installations.
Electrical safety is something that must be considered when using any device that is able to cause a hazard. Current legislation places a requirement, primarily on organisations, to make sure that electrical products are safe.
For both organisations and consumers, the Electrical (Safety) Regulations 2010 is the main piece of legislation to consider. The regulations cover activities of technicians, electricians, recyclers, and second hand dealers.
Electrical safety testing is only a test in a snapshot of time as to whether an appliance is safe. Also, not all unsafe conditions will be detected if automated test equipment is used. A thorough inspection is also needed to detect some other types of potential electrical hazards.
Electrical safety testing is carried out to detect any possible fire and electrical shock hazards.
Plug in appliances (called portable appliances in the legislation) that are used in a workplace must by law be tested to ensure that they are electrically safe. A physical inspection detects most of the electrical hazards.
The Electrical (Safety) Regulations 2010 deem appliances in service to be electrically safe if tested to the AS/NZS 3760 standard.
Sometimes poor quality manufacturing or poor design leads to issues with electrical safety in a batch of appliances. A voluntary or mandatory recall is actioned if necessary. Recent recalls in New Zealand can be viewed in this list.
An over-zealous electrical safety testing programme or cursory testing without knowledge of appliance design can lead to higher levels of e-waste. Automated appliance testing equipment can sometimes give a false positive and further work would be needed to be done to see if there is actually a fault. Discarding the item in this case is sometimes seen as an easier (but wasteful) option.
