Household circuits C1 to C13 (circuitos de la vivienda)
The separate lines into which a Spanish home installation is divided, each with its own MCB in the board. ITC-BT-25 numbers them C1 to C12 and adds C13 for electric car charging.
Why a home has several circuits
Splitting the installation into circuits gives each line the cable size and protection suited to what it feeds, and means a fault in one place does not black out the whole home. Each circuit has its own MCB (the PIA) in the fuse box.
The five basic circuits
Every home with basic electrification has at least:
- C1, lighting. All the light points. 1.5 mm² cable and 10 A breaker.
- C2, general sockets. Bedrooms, living room, hallway and the fridge. 2.5 mm² and 16 A.
- C3, cooker and oven. 6 mm² and 25 A.
- C4, washing machine, dishwasher and electric water heater. 4 mm² and 20 A.
- C5, bathroom and kitchen worktop sockets. 2.5 mm² and 16 A.
High electrification circuits
Better-equipped homes add circuits such as C8 for electric heating and C9 for air conditioning, plus others for a tumble dryer or to split lighting and sockets in large homes. C13 is the dedicated EV charging circuit, compulsory in new detached houses under ITC-BT-52.
When it affects you
If the kitchen goes dark when you turn on the oven and hob together, everything probably hangs off one undersized circuit. Older flats often have fewer circuits than today’s rules require, one of the reasons Spanish apartments seem to have so few sockets. The fix is dedicated lines, for example an induction hob circuit or a line for air conditioning, or rewiring the apartment completely in Seville, Spain.

Rewiring old apartments
Rewiring an apartment in Seville, Spain is the answer when the installation is more than 25 or 30 years old: fabric or dried-out cables, no earthing, a single RCD and a supply that cannot run the air conditioning and the induction hob at once. We renew cables, conduits, fuse board, earthing and fittings and hand you the boletín.
Kitchen electrics
Kitchen electrics in Seville, Spain need dedicated lines for the induction hob (cooktop) and the oven, another for the washing machine, dishwasher and water heater, and enough sockets along the worktop. We wire the circuits with the cross-section and protection the Spanish regulations require, in a new kitchen or when you swap gas for induction.
Induction hob circuit
The induction hob electrical requirements in Spain are clear: to fit an induction hob (cooktop) in Seville properly, the electrician runs a dedicated 6 mm² line from the fuse board, with its own 25 or 32 A circuit breaker and a connection box behind the unit. That way the hob works at full power and the electricity does not trip when it coincides with the oven.
