The main distribution board, or fuse box, is the heart of the installation: every circuit in the home starts there, and it holds the devices that protect you from fire or electric shock. Many flats in Málaga built in the 1960s, 70s and 80s still have fuse boxes with porcelain fuses or a single RCD for everything.
A modern consumer unit splits the home into separate circuits (lighting, sockets, cooker, washing machine, bathroom…), each with its own circuit breaker (MCB), and protects people with high-sensitivity RCDs. It's one of the best safety improvements for the money.
Signs your fuse box needs replacing
Porcelain fuses
Old fuse boxes with no circuit breakers or RCD. They don't meet current regulations.
A single RCD for everything
Any fault leaves the whole house without power, fridge included.
Heat, buzzing or a smell
Loose terminals or protection devices at their limit. It's a fire risk.
Frequent tripping
Circuits carrying more load than their protection devices allow.
No room to expand
You want to add air conditioning, an oven or an EV charger and there's no space in the fuse box.
You're increasing your power
The main switch and protection devices must match the new power.
What the fuse box replacement includes
- New enclosure with spare space for future additions.
- Main circuit breaker (IGA) matched to your contracted power.
- 30 mA RCDs, type A or super-immunised where appropriate.
- Circuit breakers for each circuit: lighting, sockets, cooker, washing machine and bathroom.
- Protection against transient and permanent overvoltages.
- Labelling of each circuit and RCD trip test.

Circuits and protection under the REBT
Instruction ITC-BT-25 defines the minimum circuits in a home: C1 lighting (10 A), C2 general-purpose sockets (16 A), C3 cooker and oven (25 A), C4 washing machine, dishwasher and water heater (20 A) and C5 bathroom and kitchen sockets (16 A). For high-demand electrification, extra circuits are added for heating, air conditioning or a tumble dryer.
Each circuit must be protected by a circuit breaker suited to its cable size, and all of them by 30 mA RCDs. The REBT also requires surge protection in new installations, which is especially useful on the coast because of storms and grid disturbances.
Frequently asked questions
How much does it cost to replace a fuse box?
For a home with 5 to 8 circuits it usually costs between €300 and €800 plus VAT, depending on the number of circuits, the type of RCDs and whether surge protection is added. We give you the exact price after seeing the installation.
How long will I be without power?
In a standard home the replacement is done in one day and the power is off for just a few hours. We let you know in advance so you can plan around it.
Is it compulsory to replace an old fuse box?
There's no general obligation to replace it while it works, but it must comply with the REBT when you renovate, request a new certificate or increase your power. And a fuse box with no RCD is a real risk to people.
What is a super-immunised RCD?
A type A RCD designed not to trip because of grid disturbances or the harmonics produced by modern electronics (inverters, variable-speed drives, chargers). It prevents nuisance tripping while keeping you protected.
Is an auto-reclosing RCD worth it?
In holiday homes and holiday lets, yes: if the RCD trips during a storm, it switches back on by itself after checking there's no dangerous leakage, so you don't lose what's in the freezer.
