If the RCD (differential switch) in your fuse box keeps tripping and won't reset, or trips again as soon as you reset it, there's a real fault in the wiring that shouldn't be ignored. It's not random: the RCD trips to protect you from a current leak.
At Servicio24 Electricistas we diagnose the exact cause and fix the fault on the spot, 24 hours a day, 365 days a year, anywhere in Barcelona.
Most common causes of a tripping RCD
💧 Current leak from moisture
Cables or fittings in contact with moisture in bathrooms, kitchens or older installations.
🔌 Faulty appliance
An appliance with an internal leak trips the RCD as soon as it's plugged in or switched on.
⚙️ Worn-out RCD
RCDs have a service life: after years of use they can fail even if the rest of the wiring is fine.
🔥 Circuit overload
Too many devices connected at once on the same circuit trigger the protection to trip.
🧵 Damaged wiring
Stripped, gnawed or poorly connected cables cause intermittent earth leaks.
🏚️ Old, non-upgraded wiring
Decades-old installations don't always meet current electrical safety standards and fail more often.
What to do if the RCD trips and won't reset
Don't keep resetting it
If it trips several times in a row, there's a real fault. Forcing it repeatedly can damage the installation further.
Unplug appliances
If you suspect a specific appliance, unplug it and try resetting the RCD again.

Frequently asked questions about a tripping RCD
Why does the RCD keep tripping in my home?
It's almost always a current leak to earth, caused by moisture, a faulty appliance or damaged wiring. An on-site diagnosis is needed to pinpoint the exact location.
Is it dangerous to keep resetting the RCD?
Yes. If the RCD trips and you keep resetting it without diagnosing the cause, you risk worsening the fault and increasing the risk of electric shock or fire.
Can I find the fault myself?
You can try isolating the circuit by unplugging appliances one by one, but accurately locating current leaks requires measuring equipment and professional experience.

We typically arrive within 20 minutes anywhere in Barcelona, 24 hours a day, 365 days a year.
Do you repair it the same day or do you need to order parts?
