Running an Induction Hob and Built-In Oven Together: Does Your Kitchen Have Enough Power?

Does running a hob and oven together strain a Singapore kitchen's wiring?

Most flats simply weren't wired for either appliance at its full draw. A 60 cm induction hob and a built-in oven each need their own dedicated circuit, sized to that appliance's own published power figure, not a shared one. Add a hob to a kitchen that already has an oven, or the other way round, and an electrician typically has to reassess the flat's total supply before signing off, because two new heavy circuits together can push past what an older distribution board was designed for.

How much power does a built-in induction hob actually draw?

More than most other kitchen appliances, and the figure varies a lot by model. A 60 cm induction hob's published power ranges from around 3,500 W on a smaller model to 7,400 W on a full-width one running every zone at once. That upper figure needs roughly a 32 A circuit at Singapore's standard 230 V single-phase supply, which is well above the 13 A a general power point is rated for.

A model with "no plug" on its spec sheet is designed to be hard-wired directly into a dedicated circuit by a licensed electrician rather than plugged into a socket, which is normal for a hob in this power range. The Bosch PXE675DC1E is one of the heavier draws in the catalogue at 7,400 W, so it's a useful upper-bound example to hand an electrician even if it isn't the model you end up choosing. Fujioh publishes a fuse rating rather than a wattage figure on most of its hobs, typically 15 A or 30 A depending on the model, and that figure is what an electrician sizes the circuit against directly.

How much power does a built-in oven actually draw?

Less than a high-output induction hob, but still enough to need its own circuit. Bosch's built-in ovens range from about 2,300 W on a compact single oven to 3,600 W on a larger model with steam or pyrolytic self-clean, each with its own published fuse rating. The Bosch HBG7341B1B sits at the top of that range, at 3,600 W on a 16 A fuse.

Do a hob and an oven share one circuit, or does each need its own?

Each gets its own dedicated circuit, sized to its own published power figure. A 7,400 W hob is not added to a 3,600 W oven to size a single circuit; the two are wired separately, each on a breaker rated for what that one appliance draws. What does add up is the total number of new dedicated circuits the flat's distribution board has to support, which is exactly what changes when a renovation adds a hob and an oven where a two-burner gas stove used to be.

What if your flat's existing circuits aren't rated for it?

This is the point where a real electrician has to get involved before an appliance is chosen, not after. HDB's own renovation guidelines for electrical works require any new circuit for a heavier appliance, including higher-capacity power points, to go through a licensed electrical worker, and a flat that's never had an induction hob or a 3,600 W oven may need its supply reassessed before either can be added safely. This is a wiring and permit question, not a shopping one, and it sits with the electrician doing the installation, not with the appliance's spec sheet.

How to check before you commit to a hob and oven pairing

Pull the published power figure for the exact model, not a similar one, since it varies by several hundred watts between models in the same range. Every product page on this site lists it. Hand both figures to the electrician doing the renovation before the appliances are ordered, so any circuit or distribution board work is priced and scheduled with the rest of the job rather than discovered on install day.

Frequently asked questions

Every hob in the induction hobs collection and every model in built-in ovens lists its published power requirement on the product page, alongside the cut-out it needs, so both figures are in hand before an electrician quotes the job.
