Additional protection by RCDs — What AS/NZS 3000 Clause 2.6.3 means for electricians
If you work with electrical installations in Australia, you’ll know that AS/NZS 3000 is the Wiring Rules we live and breathe. Within it, Clause 2.6.3 is one of the most important because it deals with additional protection by residual current devices, or RCDs. Over...

Choosing the Right Switchboard – How to Get It Right the First Time
The first thing in selecting a switchboard is to know precisely what it has to manage. That requires proper load calculations. What current will be drawn at peak demand? Are there big motors, air conditioning, or EV charging in the equation? Do you anticipate...

How to Detect Harmonics in Electrical Systems?
Imagine we’re supplying our electrical equipment with a nice, clean sinewave current. In theory, that should be perfect. But what actually comes out isn’t always the same—it’s distorted. That distorted waveform is what we call an electrical harmonic. Now, here’s the issue: harmonics are...

Best Practices for Workshop Organisation and Delivery in Switchboard Assembly
For switchboard construction, the finished product doesn’t rely merely on the cabling or the ultimate testing. It starts much earlier, as soon as the material arrives on site, and it goes right through to the organisation of the workshop. Attention to these small details...

Thermal Imaging For Electrical Switchboards
Thermal imaging, or infrared thermography, detects differences in temperature in electrical equipment within switchboards and related facilities. It operates by using a specialized infrared camera to measure heat in the wiring, terminations, and points of electrical component connections. Unlike a routine visual inspection, which...
