Have you been asked to install an electrical appliance that your customer purchased online? Was it likely from overseas? Perhaps lights or air conditioning units?
If you're an electrical contractor, you are responsible for the installation and selection of equipment and must comply with section 1.7 of AS/NZS 3000:2018 (Wiring Rules), even if supplied by a customer.
Some products aren't designed or tested in Australia, and they can cause electric shocks and fires.
There’s one immediate step you can take – check for the regulatory compliance mark (RCM) on the product or its packaging. That’s your assurance it’s electrically safe to use in Australia and that you can install it in accordance with the Wiring Rules.
