A few years back, I was finishing up a routine compliance check on a high-end residential renovation in Sydney. The place was packed with all the bells and whistles: smart dimmer switches, integrated LED drivers, digital timers, and electronic RCDs everywhere.

I used to love seeing that relief on my customers’ faces. But here is a wild, eye-opening fact that most Aussie homeowners have no clue about:…

Have you ever stopped to look at that humble metal box sitting on the side of your house, heard a faint, steady hum, and thought, “Well, as long as the ice cream in the freezer stays frozen, we’re all good”? Honestly, I used to think the exact same way. That was until I found myself…
