More powerful M12 tools from Milwaukee

When Caleb Marshall first looked at Milwaukee Tools’ new M12 cordless soldering iron, it looked quite big and heavy. But once he got it in his hand and started using it, he soon discovered how easy it was to use.

Marshall was one of the first electricians in New Zealand to try the new portable soldering iron and he tried it out soldering some LED strip lights on site.

For this type of job in a remote location he normally uses a gas iron, so he was interested to see if a cordless electric iron could do better than the intense heat generated by the butane gas tool.

“The response was immediate. The cordless Milwaukee got hotter way faster than my gas iron and held its heat without going red hot and molten.

“Not only did the Milwaukee cordless perform better, it maintained a good working temperature in the wind where my gas soldering iron would have struggled.”

What Marshall discovered is what underpins Milwaukee Tools new-tool development strategy: to make cordless tools more powerful than corded tools and better suited to specific tasks tradesmen regularly undertake.

Keeping AS/NZS 3000 on track

Concern over the future of AS/NZS 3000 and where it is heading under Standards Australia control has prompted Australasian electrical regulators to set up a working group to take a closer look at how the Australian standards organisation is developing its Wiring Rules.

With AS/NZS 3000 moving further away from alignment with the international standard for electrical installations with every modification it produces, electrical regulators on both sides of the Tasman have become increasingly concerned with the evolution of the joint electrical installation standard and want to arrive at a common position on how to deal with it.

Regulators from the eight Australian states and territories and New Zealand coordinate their activities through the Electrical Regulatory Authorities Council (ERAC), and it is an ERAC working group that will address matters such as the growing disconnection between AS/NZS 3000 and its source: IEC 60364.

Because AS/NZS 3000 is cited in various ways by these regulators, it plays a pivotal role in how they meet their obligations to ensure the regulations they produce will provide for the safety of the public.

Failure to certify is only half the issue

A woman living on her own in Auckland and needing electrical work done fell victim in January to an unscrupulous electrician when he demanded cash for the job and refused to supply a CoC.

Seeking help, the woman contacted the EWRB and Energy Safety but could not get the answers she needed. She found the New Zealand Electrical Inspectors Association (NZEIA) website and contacted its president, Richard Gibbens, who was able to answer her questions and explain how the law worked.

Gibbens says the woman wanted to know if she was entitled to receive a CoC and wanted a tax invoice for the work, so he advised her on what steps she could take to get both documents supplied as the law requires.

“She told me that the electrician, who had been recommended to her, offered to do a cheap job in return for cash payment and pushed this from the start. Her response was that she was happy to pay the going rate and wanted the work to be covered by an invoice and a CoC.

“She had been told previously by a friend that without a CoC her insurance company would not pay out if the house caught fire and the new work was blamed as the cause of the fire.

New ACQ580 – securing the flow of water

The launch of ABB’s new ACQ580 variable speed drive is not just a leap forward in the evolution of industry-specific drives, it promises to change the way water pumps are managed for optimum performance. ABB’s Drive Business manager John Keir says the advanced engineering in the new ACQ580 changes any definition of what makes a drive fit for a water pumping purpose and invites engineers and integrators to review their designs to take advantage of the new features introduced by the ACQ580.

Designed to be used in water and wastewater treatment plants, pumping stations, desalination plants, industrial wastewater facilities and irrigation systems, Keir says the ACQ580 is compatible with all pumping applications including inflow pumps, transfer pumps, dosing pumps, sludge pumps, booster pumps, and submersible pumps.

Now part of ABB’s all-compatible drives portfolio, Keir says this drive is the perfect solution to support energy-neutral solutions for water plants.

“It provides reduced energy consumption through standby and sleep modes, and application specific control such as level control, booster pump control, multi-pump control, as well as pump cleaning functionality. The ACQ580 includes accurate power measurement and built-in energy efficiency modes and calculators, allowing you to optimise your pump and operation in maximum efficiency ranges.”

Lighting up New Zealand in a smart way

Entering the New Zealand market with a full portfolio of lighting options, Aurora Lighting is launching more than just multiple ranges of LED luminaires and lighting fixtures.

Thanks to the recent development of its AOne control system, Aurora Lighting is also offering affordable smart lighting and end-to-end lighting solutions for almost any application, says managing director of Aurora Lighting in Australia and New Zealand, Fred Nimarota.

Aurora’s New Zealand operation is being set up with three vertical lighting sectors: Trade, Projects and Retail along with a fourth complementary group that takes care of smart lighting solutions and Internet of Things (IoT) connectivity.

Nimarota says Aurora Lighting presents the modern face of luminaire design and manufacture, and is now one of the few lighting companies in New Zealand on a scale that can operate effectively in both the trade and project space.

Aurora Lighting was established in the UK in 1999 as an early adopter of LED technology and now trades in over 70 countries, which places the Aurora Group as one of the world’s largest privately owned LED lighting manufacturers.

Street lighting upgrades

The upgrading of Wellington City’s street lighting is underway with some 15,000 legacy street lamps now being replaced with smart LED luminaires.

Wellington City Council’s team leader for transport Infrastructure, Kevin Turner, says the citywide project has been divided into 20 work packages of approximately 750 lights each. Three of the four contractors undertaking the project are now installing the new LEDs and the fourth contractor is set to go. The contractors have indicated they might employ up to three crews each to achieve target productivity.

Turner says the Council spent two to three months looking at luminaire options and narrowed the choice down to a single product that offered the best solution for the Wellington conditions and topography.

Using light to promote health

While we wait for more scientific studies to be completed on the impact of artificial lighting on human health, there is ample evidence to show that spectra and colour temperature can have a direct effect on human responses and behaviour.

There will no doubt be more debate on the balance between health, safety and aesthetics in the design and selection of indoor lighting, particularly concerning the effect of light levels and blue-rich white light on circadian rhythms and physical and mental health.

We know that exposure to light, especially to blue light, can change our sleep/wake patterns and these changes can cause health issues. It is also known that exposure to blue light can harm the eye itself and is a risk factor in macular degeneration.
