Professional Electrical Fault Diagnosis Across London
When lights flicker, fuses trip or circuits fail, it's time to call the professionals. At RCD Electrical, we understand that electrical faults can disrupt homes, delay businesses, and potentially become dangerous. That’s why our NICEIC-certified electricians follow a clear, structured six-step process to identify and fix faults quickly, safely, and effectively.
Step 1: Client Consultation & Symptom Review
The fault-finding journey begins with you. When you contact RCD Electrical on 02034882928 or via info@rcdelectrician.co.uk, our experienced team takes a detailed account of the symptoms you’ve noticed — whether it’s random power loss, overheating sockets, or faulty lighting. This step gives us crucial insight into where to begin testing and what problems may be present.
Step 2: Initial Visual Inspection
On arrival, our qualified electricians carry out a thorough visual inspection of the electrical installation. This includes checking the consumer unit, sockets, switches, and wiring routes for any signs of damage, overheating, or wear. It helps to quickly rule out obvious issues like loose connections, broken components, or outdated equipment.
Step 3: Testing for Safe Isolation
Before any fault-finding tests begin, safety is paramount. RCD Electrical ensures safe isolation procedures are followed to eliminate the risk of electric shock or damage to appliances. We disconnect the affected circuits properly, verify isolation, and prepare the system for deeper testing.
Step 4: Systematic Electrical Testing
Using industry-grade diagnostic tools, we begin methodical testing. This may include:
-
Continuity Testing: Ensures that conductors are intact and properly connected.
-
Insulation Resistance Testing: Identifies leakage paths and potential short circuits.
-
Polarity Testing: Confirms correct wiring of live, neutral, and earth conductors.
-
Earth Fault Loop Impedance: Assesses the effectiveness of the earthing system.
Our NICEIC-approved electricians don’t guess — they test with precision.
Step 5: Fault Diagnosis & Root Cause Analysis
Once we’ve collected all necessary data, we carefully interpret the results to pinpoint the root cause of the fault. Whether it’s water ingress in fittings, damaged cabling within walls, aged consumer units, or overloaded circuits — our technicians explain the issue clearly, along with recommended solutions.
Step 6: Rectification & Verification
Once diagnosed, the fault is promptly rectified using quality-approved materials and components. After repairs, we re-test the system to verify the issue has been fully resolved and that your installation now meets current safety standards. A final safety certificate may be issued, depending on the work completed.
