The key points
- Choose the exact model before the electrical design is finalised.
- Check the cut-out and ventilation, not just the appliance width.
- Coordinate gas, electrical and bench work before removing the old cooktop.
Start with the installation sheet
The front-page product description does not contain everything the installer needs. Download the manufacturer’s installation sheet for the exact model. It identifies connection arrangements, load and physical clearances. Keep this alongside the product dimensions and warranty information.
Do not assume a wider or more expensive cooktop has the same supply requirements as the old one. Model-specific information lets the electrician assess the existing circuit and quote any changes before the appliance arrives.
Have the existing supply assessed
Send an accessible photo of the switchboard front and explain where the kitchen sits relative to it. The electrician may need to inspect on site to assess cable size, protection and supply capacity. A free space in the board is not by itself proof that the installation is ready.
Include other planned loads such as an EV charger, hot-water upgrade or extra air conditioning. The goal is to understand the combined plan, even if only the cooktop is being fitted now. Do not change a breaker or wiring yourself.
- Exact model and connection requirements.
- Existing appliance and circuit details.
- Distance and access from the switchboard.
- Other major electrical upgrades being planned.
Measure the opening and agree who handles alterations
The external glass dimensions and the cut-out are different measurements. Check the required opening, bench thickness, ventilation and clearances against the manufacturer’s instructions. Drawers or an oven underneath can affect the available space.
Electrical installation does not automatically include stone cutting, cabinet changes or splashback repairs. Confirm each trade’s scope and sequence. If you are renovating, the cabinetmaker and electrician should work from the same final appliance information.
Sequence a gas-to-induction change carefully
A gas cooktop must be disconnected and its connection made safe by an appropriately qualified gasfitter. An electrical licence alone does not authorise that gas work. Confirm who is arranging it and when, rather than assuming it is covered by the appliance delivery.
Have the bench ready before the electrical fit-off is booked. If cooking facilities will be unavailable overnight, plan meals and access accordingly. A coordinated date is especially useful in an occupied family kitchen.
Keep a clear handover checklist
Ask for a demonstration of the isolation arrangement and basic controls. Keep the model information and any installation paperwork in a place you can find later. Check cookware suitability using the manufacturer’s guidance before replacing all your pans.
Electrical installation work in Victoria requires a Certificate of Electrical Safety. Keep it with the appliance documents, particularly when the work includes a new circuit.
- Appliance stable and installed to its instructions.
- Controls and isolation explained.
- Work area and included removal complete.
- Electrical paperwork and warranty details retained.
Quick answers
- Why does my oven trip the power when I turn it on?Most often an oven element has failed or taken in moisture, and current is leaking to earth, which trips the safety switch.
- What is the switch next to my outdoor unit for?It's an isolating switch that cuts all power to the air conditioner, so a technician can work on the system safely without relying on the switchboard.
- Why does my electric heater trip the safety switch?A safety switch trips when it detects electricity leaking to earth, and portable heaters are a common cause.
- How many appliances can I plug into one power board?It's the total load that counts, not the number of sockets.
