Induction Hob Electrical Requirements in Malaysia
The installation usually fails because the board was sized after the hob was ordered. This guide is the planning sequence for 240 V tabletop units and three-phase commercial plant.
Written by Better IH Malaysia · Updated 25 August 2026 · For Malaysian homes and commercial kitchens
What Malaysian kitchens actually supply
Single-phase sockets and lighting in Malaysia are 220–240 V, 50 Hz. That is the supply for most tabletop induction cookers and built-in induction hobs in this catalogue (typically 1 kW to 5 kW). Line-to-line three-phase for commercial plant is commonly 380–415 V (this catalogue lists 380–420 V 3N for ranges, wok stations, and large fryers).
Do not assume a 13 A plug is enough. A 3.5 kW hob at 230 V draws about 15 A continuously at full output; a 5 kW hob about 22 A. Those figures are why commercial tabletop units are often supplied without a plug — the electrician terminates to a dedicated circuit.
Planning loads (for discussion with a licensed electrician)
| Hob class | Typical supply in this catalogue | Planning note |
|---|---|---|
| Warmers ~230 W | 220–240 V | Not a cooker. Still use a proper outlet; do not share a random trailing socket with a 3.5 kW hob. |
| About 1–2.2 kW built-in / compact | 220–240 V | Dedicated circuit is still the right habit in a new kitchen. |
| 3–3.5 kW commercial tabletop or built-in wok | 220–240 V | Dedicated MCB. Expect hard-wiring on many commercial bodies. |
| 5 kW tabletop | 220–240 V | Treat as a heavy single-phase load. Confirm the board has spare capacity. |
| 8–15 kW fryer, griddle, wok station, multi-zone range | 380–420 V three-phase | This is kitchen plant. Needs a planned isolator, not a wall socket. |
Dedicated circuit, RCD, and isolation
Share a 3.5 kW cooker with a rice cooker, blender, and kettle on a trailing board and you will trip it. Give the hob its own circuit from the distribution board, with an accessible isolator so the unit can be switched off for cleaning and service.
Residual current protection (RCCB/RCBO) is normal in Malaysian boards. Induction appliances can nuisance-trip a poorly selected device if several units share one sensitive RCD. That is a coordination issue for the electrician, especially on a commercial line with several cookers.
Built-in hobs need air under the counter as well as amps
A built-in induction hob dumps heat into the cabinet. If the carpenter closes the cupboard with no ventilation gap, the hob will throttle or cut out even on a correctly sized circuit. Confirm cut-out, cable entry, and clearance on the model page (for example BT-350T) before the worktop is cut.
Tabletop units still need a stable, non-flammable table and space for the fan intake. Do not park a 5 kW cooker against a wall that blocks the vents. See built-in vs tabletop.
Three-phase commercial plant
If you are replacing a multi-burner gas range with an EW5/5T induction range or specifying the EW15WOKB 15 kW wok station, budget for three-phase as part of the kitchen, not as an accessory. The connected load can be 15–30 kW. That is in the same conversation as extraction, grease filters, and floor drainage — not a “buy a thicker plug” conversation.
Confirm 3N voltage, earth, and isolator location with the contractor before you lock the furniture layout. Moving a 110 cm wok station after the floor trap is poured is expensive.
Recommended sequence on a Malaysian project
- Pick the cooking job (wok, flat, fry, buffet) and the installation type.
- Open the model page and write down wattage, voltage, and dimensions.
- Send that page to the electrician before the carpenter cuts the counter.
- Only then order the hob. Warranty and commissioning assume the supply matches the rating plate.
Frequently asked questions
Can I plug a 3.5 kW commercial induction cooker into a normal 13 A socket?
Often no. At 230 V, 3.5 kW is about 15 A at full output. Many commercial bodies are supplied without a plug so they can be hard-wired to a dedicated circuit. Confirm with the electrician and the rating plate.
What voltage do Better IH commercial ranges use?
Free-standing ranges, 10 kW-class fryers, griddles and the 15 kW wok station are listed at 380–420 V three-phase. Compact tabletop and many built-in hobs are 220–240 V. Always check the specific model page.
Do I need a licensed electrician?
Yes for new circuits, three-phase work, and hard-wiring. Malaysian electrical work should be carried out by a competent person. Better IH Malaysia can advise on the appliance; the electrician is responsible for the board.

What Wattage Induction Hob Do You Need in Malaysia?
Wattage is the first number the electrician needs. This page maps 2 kW pantries, 3.5–5 kW restaurant cookers, and 10–15 kW wok plant onto typical Malaysian supplies.
How Much Electricity Does an Induction Hob Use?
Nameplate watts are not your bill. This guide shows how to estimate kWh from wattage, hours, and duty cycle, using the kinds of loads in a Malaysian home or F&B kitchen.
Installing a Built-In Induction Hob in Malaysia
Most failed drop-in jobs are joinery, not electronics. Cut to the written dimensions, leave the cupboard breathing, and hard-wire the circuit before you power the glass.
