Installing an electric oven is a manageable project when you follow the right sequence — but skipping even one step can create a real safety hazard or void the appliance warranty. The video above walks through the physical installation clearly; this guide adds the context that matters specifically for Greek kitchens, holiday rentals, and hotel units, including local wiring standards and what to check before the power goes back on. Work methodically, respect the electrical work, and your new oven will be running safely within an afternoon.
Types of Electric Oven and What Changes Between Them
Electric ovens in Greece fall into two main categories: freestanding cookers (which combine hob and oven in one unit) and built-in ovens (fitted into a cabinet housing, with a separate hob). The installation process shares the same electrical principles but differs in how the appliance is secured and ventilated. Built-in ovens slot into a dedicated housing unit and are held in place by side screws; freestanding models simply push into a gap between cabinets and are levelled on adjustable feet.
Most residential and rental properties in Greece use a 230 V single-phase supply for ovens up to roughly 3.5 kW. Larger ovens and combination units may require a dedicated 32 A circuit. Always check the appliance's data plate and compare it against the circuit breaker rating in your distribution board before you begin.
What You Need Before You Start
Gather the appliance manual, a voltage tester, a flathead and Phillips screwdriver, a spirit level, cable clips, electrical tape, heat-resistant flex (at least 1.5 mm² for most domestic ovens, 2.5 mm² for heavier units), and a connection box or cooker control unit with an isolation switch. In Greece, a dedicated oven circuit must terminate at a switched fused spur or cooker control unit — you cannot wire an oven directly into a standard 13 A socket.
If the existing wiring in the kitchen is old aluminium cable or the socket point shows signs of heat discolouration or burning, stop and call a licensed electrician (hlektrologos) before continuing. Greek electrical regulations (ELOT EN 60364) require that any new or replacement hardwired appliance connection be signed off by a licensed technician who issues a DEI compliance certificate (Υπεύθυνη Δήλωση Εγκατάστασης) — essential for rental properties and insurance purposes.
How to Install an Electric Oven: 5 Steps
- 1
Switch Off Power and Verify the Circuit is Dead
Go to your distribution board and switch off the breaker for the kitchen circuit — or the dedicated oven circuit if one exists. Use a non-contact voltage tester at the wiring point where the oven will connect to confirm there is absolutely no live voltage before touching any wires. Tape over the breaker switch and, if other people are in the property, put a note on the board. Never rely on simply turning the oven control knob to 'off'.

Prepare the Housing and Position the Oven
For a built-in oven, measure the cabinet opening against the appliance's installation dimensions (found in the manual). Most standard European built-in ovens fit a 560–600 mm wide, 590 mm tall housing. Remove the cabinet shelf or old appliance, clean out any debris, and confirm the housing has the ventilation clearances specified in the manual — typically a 5–10 mm gap at the rear and ventilation slots at the top or bottom of the door. For a freestanding oven, adjust the levelling feet until a spirit level reads true on both axes; an unlevel oven causes uneven baking and can stress the door seal.

Connect the Electrical Supply
Feed the supply cable through the oven's cable entry point and connect the conductors to the terminal block on the back of the appliance. Greek domestic wiring uses brown for live, blue for neutral, and green-yellow for earth — match these to the L, N, and Earth terminals on the oven terminal block and tighten each screw firmly. Double-check that no bare copper is exposed outside the terminal block and that the cable clamp grips the outer sheath, not just the inner cores, so a tug on the cable cannot pull conductors loose. If your appliance requires a three-phase connection, this step must be performed by a licensed electrician.

Slide the Oven into Place and Secure It
Carefully slide or lift the oven into its housing or into the kitchen gap. For built-in models, open the oven door to access the side fixing screws — most manufacturers supply these in the accessory bag. Drive the screws into the pre-drilled holes in the cabinet side walls until the oven front sits flush with the surrounding cabinetry. For freestanding models, some units include an anti-tip bracket that should be screwed to the floor or the adjacent cabinet; fit it — it is a safety device, not optional. Check that the door opens and closes smoothly and that the door seal makes even contact all the way around.
- 5
Restore Power and Test
Go back to the distribution board and restore the oven's circuit breaker. Set the oven to a mid-range temperature (around 180 °C) on the conventional bake function and let it run for 20–30 minutes — this 'burn-off' cycle evaporates protective coatings and oils applied at the factory. Expect a slight smell and a little smoke; this is normal on first use. After the cycle, verify that all heating elements and the oven light work, test the timer and any electronic controls, and check around the terminal connection for any warmth, burning smell, or discolouration, which would indicate a loose connection that needs immediate attention.

FAQ
- Do I need a licensed electrician to install an electric oven in Greece?
- For any hardwired connection — which covers all built-in ovens and most freestanding models above 3.5 kW — Greek regulations require the work to be documented by a licensed electrician (hlektrologos) who issues a DEI compliance certificate. This is especially important for holiday rentals, where insurance and platform liability depend on certified installations. A straightforward oven swap on an existing, correctly rated circuit is often done by a competent handyperson, but the paperwork and final sign-off should still involve a licensed professional.
- What cable size do I need for an electric oven in Greece?
- Most domestic ovens (up to about 3.5 kW) are wired with 2.5 mm² three-core heat-resistant flex on a 16 A or 20 A circuit. Larger ovens, range cookers, or combined oven-hob units that draw more current typically need 6 mm² cable on a 32 A circuit. Always check the data plate on the appliance for its maximum rated current and match the cable and breaker to that figure — never undersize the wiring.
- How long does it take to install a built-in electric oven?
- For someone replacing a like-for-like appliance where the housing and wiring are already in place, the physical installation takes 30–60 minutes. If the housing needs adjustment, new ventilation needs to be cut, or fresh wiring needs to be run from the distribution board, allow half a day. Add the first-use burn-off cycle (around 30 minutes) before cooking anything in the new oven.
