RCD Testing In Glasgow
Professional RCD testing, replacement and upgrade services. Ensure your life-saving devices work when you need them most.
Your RCD Is Your Last Line of Defence
RCDs (Residual Current Devices) are designed to save your life by cutting power in milliseconds if electricity leaks to earth. But like any safety device, they can fail. We test, replace and upgrade RCDs across Glasgow to ensure this critical protection works perfectly. Whether your RCD is nuisance tripping, has failed its test button, or you need advice on upgrading to modern types, we have the expertise to keep you safe.
RCD Services We Provide
RCD Function Testing
Test every RCD in your consumer unit to ensure it trips within the required time at the correct fault current.
RCD Replacement
Replace faulty, expired or recalled RCDs with modern A-type or B-type devices appropriate for your installation.
Nuisance Trip Investigation
Diagnose why your RCD keeps tripping randomly and fix the underlying earth leakage or equipment fault.
RCD Upgrades
Upgrade from basic AC-type RCDs to modern A-type or high-immunity SI-type RCDs for better protection and fewer false trips.
