The new program confirms which home battery products have been tested against the industry’s best practice guidelines… Products that qualify for the Battery Assurance Program … have been independently tested to confirm they are up to the necessary electrical safety and quality standards.
(Letter to the Sydney Morning Herald, March 20th, 1890, about the electrification of Sydney’s street-lighting, replacing gas, and the electrification of the steam-tram network. Post borrowed from the Old Sydney Album in Facebook)..
IF ORDINARY PRECAUTIONS ARE TAKEN THERE IS INFINITELY LESS DANGER IN THE USE OF ELECTRICITY THAN IN THAT OF GAS.
During the past decade (1880-90) there were in the whole of Europe only 13 deaths occasioned by electricity.
The city of Sydney,with a population of less than the 1000th part of that of Europe, can furnish a much heavier record of mortality against gas, and yet people have long ago ceased to complain of the danger attaching to the use of the latter agent.
There are far more deaths attributable to the careless use of “Rough On Rats” and many other household poisons, than to electricity.
No less than 300 persons were injured and 135 killed by the explosion of a cartridge factory at Antwerp last September, and 13 women were killed by the collapse of a carpet factory at Glasgow last November, whilst nearer home, and still more recently, about 150 lost their lives in the ill-fated SS QUETTA – still no one suggests dispensing with cartridge and carpet factories and mail steamers.
Every week has something to record in the way of boiler explosions, killing in the majority of cases over a dozen persons; gas explosions are items of every-day occurrence, yet the cranks who become furious at the bare mention of an electrical accident hardly think such mishaps worthy of mention.
During the year ending December 31, 1888, out of a total of 1258 deaths by accident in New York, electricity gave only 6, versus illuminating gas 32, kerosene 17, and drowning 173 – this alone should suffice to show that electricity is, relatively speaking, safe, and the testimony may be considered of especial value, coming from New York, where nearly every street, shop, and store of importance, and a very large number of public buildings and private dwellings, are lit by electricity, whilst a large number also of factories and workshops and tramway systems are supplied with power by the same agent”.

Consumers are set to benefit from improved safety standards in the gas and electrical goods industry when amended regulations commence on 1 September 2018.
The Act will provide multiple benefits, including:
- Implementing a consistent compliance and enforcement regime for both gas and electricity energy sources;
- Authorising NSW Fair Trading officers to seize or remove any unsafe gas appliance where an offence has been committed or the appliance is unsafe;
- Aligning the maximum penalties for offences relating to gas safety with those relating to electricity safety; and, most importantly,
- Addressing deficiencies in the current gas consumer safety provisions to better provide consumers and the NSW public.
Dr Quach says that unlike ordinary batteries, which take the same amount of time to charge no matter how many you have, the theory is that quantum batteries would charge faster the more you have of them.
“If one quantum battery takes one hour to charge, then two would take 30 minutes, three would take 20 minutes, and so on. If you had 10,000 batteries, they would all charge in less than a second,” he said.
The university’s simulation (was asked) to use Shor’s quantum factoring algorithm to find the two prime numbers (of) the semi-prime 961 307…. This enabled the simulation to solve the equation using just 13.8 terabytes of memory (instead of up to 18 000 petabytes).
The 2018 edition of the Wiring Rules (AS/NZS 3000:2018) has now been released. You can purchase the new standard on the SAI Global’s website.
Some of the changes from the previous edition include:
- new requirements for safety switches
- enhanced requirements for MEN earthing systems, including bonding of pool structures and wet areas
- increased mechanical protection for cables installed within a ceiling space
- additional installation requirements for electrical appliances, accessories and equipment
- enhanced safety requirements for electrical equipment installed in locations exposed to water
- five new appendices:
- continuity of supply for active assisted living
- electrical conduits
- installation of arc fault detection devices
- guidance for the installation and location of electrical vehicle charging stations
- DC circuit protection and switching devices.
Measurement Law Review
The Australian Government is conducting a thematic review of the legislative framework underpinning Australia’s measurement system. The Measurement Law Review aims to identify any aspects of Australia’s measurement framework that can be modernised, streamlined or simplified to better meet the needs of a modern economy. Options for reform are expected to be presented to the Australian Government in 2020.
