Switchboard Upgrade


The owners of a small business called on Zehn Electrical Services to diagnose a fault in a hot water service (HWS).

While diagnosing the HWS issue, we noticed that the power and lighting circuits didn’t comply with AS3000 wiring rules because none of these circuits were on safety switches.

Safety switches minimise the risk of electrical shock hazards to personnel during earth leakage faults and would be a huge issue if not rectified before an electrical incident took place.

The owners were gobsmacked and asked us to retrofit the main and distribution switchboards to comply with current AS3000 electrical standards.

The Zehn Electrical solution

  • We planned the job to work outside their hours of operation to minimise disruption
  • Safely isolated electrical supply to remove existing circuit breakers
  • Installed new safety switches
  • Tested and verified the installation of circuit protection for each circuit affected by the upgrade

“Justin has worked on a number of electrical issues for Amazing Oils over the last year or so. We have always found him to be extremely professional, friendly and efficient. He is always very considerate of how having the power turned off will affect our business so has come in as early as 6.30am to make sure that the job is completed by the time we need to open the office/warehouse. We would have no hesitation in recommending his electrical services to other businesses.” – Uma, Amazing Oils
