Electrical Fault Finding in Highbury & Islington – RCBO Tripping Due to Damaged Cable
Our team of Electricians in Highbury & Islington recently attended an emergency call-out after a homeowner reported that an RCBO (Residual Current Circuit Breaker with Overcurrent Protection) was repeatedly tripping, leaving part of the property without power.
Electrical faults that cause protective devices to trip should never be ignored. They are designed to disconnect the power supply when a fault is detected, helping to prevent electric shock, fire hazards and damage to the electrical installation.
Using professional diagnostic equipment, our experienced electricians quickly identified the cause of the problem, carried out the necessary repairs and safely restored power to the property.
The Electrical Problem
The customer had experienced repeated RCBO tripping, with the circuit disconnecting shortly after being reset. This prevented the affected sockets from operating correctly and caused ongoing inconvenience.
An RCBO combines the protection of both an MCB (Miniature Circuit Breaker) and an RCD (Residual Current Device), providing protection against overloads, short circuits and earth leakage faults. When an RCBO repeatedly trips, it is usually an indication that an electrical fault exists somewhere on the circuit and requires investigation by a qualified electrician.
Rather than replacing components unnecessarily, our engineers carried out a systematic Electrical Fault Finding process to identify the exact cause of the problem.
Our Solution
After safely isolating the circuit, our electricians carried out a series of electrical tests using calibrated professional testing equipment.
Through insulation resistance testing and circuit diagnostics, we identified a damaged section of cable creating a fault between the live conductor and the protective conductor (earth). This fault was causing the RCBO to operate correctly and disconnect the supply to maintain electrical safety.
Once the damaged cable had been located, we:
- Safely isolated the electrical supply
- Carried out comprehensive electrical fault finding
- Located the damaged section of cable
- Repaired the faulty wiring
- Retested the circuit in accordance with BS 7671 (18th Edition Wiring Regulations)
- Verified the correct operation of the RCBO
- Restored power to the property
Following completion of the repair, all electrical test results were satisfactory and the installation was safely returned to service.
Why This Matters
A repeatedly tripping RCBO is often the first sign that an electrical installation has developed a fault. Continuing to reset the device without investigating the underlying cause can lead to further damage or create unnecessary safety risks.
Professional electrical fault finding enables faults to be identified accurately, avoiding unnecessary disruption and preventing costly repairs later.
Common causes of RCBO tripping include:
- Damaged electrical cables
- Earth faults
- Faulty socket outlets
- Damaged accessories
- Water ingress
- Faulty appliances
- Wiring deterioration
Our electricians use advanced testing equipment to diagnose faults efficiently, ensuring repairs are carried out safely and correctly the first time.
