RCD Replacement
A failed or constantly tripping RCD leaves circuits unprotected or your power unreliable. We diagnose and replace faulty RCDs and RCBOs across Marbella and the Costa del Sol.
An RCD protects you from electric shock by cutting power when it detects a fault. When one fails, sticks or trips for no clear reason, it needs proper diagnosis — sometimes the device itself has failed, sometimes it's reacting to a genuine fault on a circuit. We test to find out, replace the device where needed and confirm the protection works correctly.
Covering Marbella, Estepona & across the Costa del Sol
