Kitchen electrics in Seville, Spain: dedicated circuits for induction hob, oven and dishwasher

Why the kitchen needs its own circuits

The kitchen concentrates the most power-hungry appliances in the home: induction hob, oven, dishwasher, washing machine (in many Seville flats it sits in the kitchen or in the utility gallery), water heater (termo), microwave and extractor hood. If they all hang off one or two lines, breakers trip, sockets heat up and cables work at their limit.

That is why the Spanish Low Voltage Electrotechnical Regulation, in ITC-BT-25, sets out specific circuits for the kitchen. If you are used to a British ring main, the Spanish approach is different: radial circuits, each for a defined use, with a breaker sized to its cable.

Kitchen circuits under ITC-BT-25

For high-power induction hobs, which can reach about 7,000 W, a dedicated 6 mm² line with a 25 A or 32 A circuit breaker, depending on the hob, is common. We explain it in detail on induction hob circuit.

What your kitchen electrics include

• A line for the hob, induction or ceramic, with an accessible connection box.
• A line for the oven, shared with the hob or separate depending on the power.
• A circuit for the washing machine, dishwasher and water heater, with earthed sockets and protection against damp.
• Auxiliary sockets spread along the worktop and the island, and dedicated sockets for the fridge, hood and microwave.
• Lighting under the wall units, in the hood and on the ceiling. To add points, see extra sockets and lights.
• Adapting the fuse board with the new breakers and, if needed, another RCD. See fuse board replacement.

How we work

1. Kitchen plan. We start from the units and appliance layout to place each socket at the right height and in the right space.
2. Fuse board and power check. We confirm whether the fuse board can take the new circuits and whether your contracted power is enough.
3. Chasing and wiring while the walls are open, before tiling and fitting the units. If the kitchen is part of a bigger project, we coordinate it within the renovation electrics.
4. Connecting the appliances once the fitter has finished the units.
5. Tests of insulation, earthing and RCD, and a certificate if the work requires it.

Kitchens without gas: switching to induction

More and more families in Seville are giving up the butane bottle or the gas supply for an all-electric kitchen. The change needs three things: a dedicated line for the hob, its protection in the fuse board and a contracted power that can carry the hob together with the air conditioning and the rest of the home. If the power is not checked, the symptom soon appears: the power goes off while you cook dinner. If that happens, see MCB keeps tripping and, if your power falls short, increase contracted power.

Kitchens in Seville flats

In the 1960s and 1970s flats of Nervión, Los Remedios, Heliópolis or La Macarena, the original kitchen usually has a single line for everything and, with luck, one socket for the washing machine. A typical renovation: the family opens the kitchen onto the living room and wants an island with an induction hob, a tower oven, a dishwasher and a worktop full of small appliances. With the walls open we run the hob, oven and washing lines from an adapted fuse board and spread sockets along the worktop and the island. In new homes in Sevilla Este or Entrenúcleos the kitchen already has its circuits, and what is most requested is a new line to change the hob or for an island that was not planned.
