Overview
Residual Current Devices (RCDs) are critical components of electrical safety systems — designed to disconnect power instantly when a fault or imbalance is detected.
However, RCDs can fail mechanically, degrade over time, or fall outside required trip-time tolerances without visible warning.
Our NICEIC-certified engineers carry out structured RCD inspection and testing to verify:
- Correct operation
- Compliance with BS 7671 disconnection times
- Ongoing reliability of protective devices
Regular RCD testing supports compliance under:
- BS 7671 (IET Wiring Regulations)
- Electricity at Work Regulations (EAWR)
- Insurer and audit requirements
RCD verification is often delivered alongside full Fixed Wire Testing (EICR) inspections, or as a standalone compliance programme for high-demand sites.
Who This Service Is For
RCD testing is essential for:
Key benefits include:
Manufacturing facilities
Pharmaceutical sites
Warehouses and logistics centres
Commercial offices and retail environments
Facilities managers responsible for electrical compliance
If your site relies on protective devices to prevent shock, fire, or escalation of electrical faults, structured RCD verification is critical.
What We Deliver
Testing of Type AC, A, B, and S RCDs
Trip-time and ramp testing to BS 7671 limits
Verification of correct disconnection times
Functional testing under simulated fault conditions
Asset identification and labelling for future inspection
Clear pass/fail reporting with remedial recommendations
Integration with full Electrical Installation Condition Reports (EICR)
Optional inclusion within broader Electrical Maintenance & Compliance Services
We carry out testing during operational hours, phased shutdowns, or weekends — ensuring minimal disruption to production environments.
Benefits of Regular RCD Testing
Routine RCD verification ensures protective devices function correctly when needed most.
Key benefits include:
Demonstrable compliance with BS 7671 and EAWR
Reduced risk of electric shock incidents
Protection against undetected protective device failure
Early identification of mechanical or sensitivity faults
Improved audit and insurer readiness
Clear documentation for internal safety records
Safer environments for staff, contractors, and visitors
Structured testing demonstrates proactive electrical risk management — not reactive correction.
Why Structured RCD Testing Matters
In high-demand commercial environments, RCD failure is rarely visible until a fault occurs.
Routine verification ensures devices operate within required trip-time limits — preventing escalation of electrical faults and protecting both personnel and production systems.
For regulated sectors such as pharmaceutical and manufacturing, this level of control is essential.

Case Study
Pharmaceutical Compliance Testing Programme — Beeston, Nottingham
Challenge:
A major pharmaceutical manufacturing facility required full RCD testing and verification across its live electrical infrastructure.
The site required:
Compliance with BS 7671
Zero disruption to sensitive production
Asset-level traceability for audits and insurer review
With nearly 1,000 RCDs installed across multiple distribution boards, paper-based reporting was insufficient for long-term compliance control.
Solution:
ElectroGlow delivered a structured, compliance-led RCD testing programme tailored for a regulated industrial environment.
Our engineers:
Tested 991 RCD protective devices across the full site
Carried out all testing during weekends to minimise production risk
Assigned each RCD an individual QR code, linking directly to test certification
Implemented a secure online compliance portal with real-time asset history
Delivered clear reporting aligned with pharmaceutical audit standards
The programme was integrated alongside the site’s wider Maintenance & Compliance Services
Results achieved:
991 RCDs tested, verified, and logged under a structured compliance system
Zero disruption to live production
Full asset traceability through QR-coded device tracking
Real-time compliance visibility via secure portal
Insurer- and audit-ready documentation issued immediately
Why Businesses Choose ElectroGlow

Structured compliance-led approach
Minimal operational disruption
Clear, audit-ready documentation
Integration with EICR and ongoing maintenance schedules
Proven experience across regulated environments
Protection that works when it matters most.
Frequently Asked Questions
Answers to common questions about our solar and EV solutions.
How often should RCDs be tested?
RCDs should be manually tested every 6 months using the built-in test button. Professional testing and recorded verification is typically required every 1–3 years, depending on site risk level, operational environment, and insurer requirements.
Can RCD testing be carried out during live operations?
Yes. We regularly work within operational commercial and industrial facilities and can phase testing or schedule out-of-hours and weekend works to minimise disruption.
Will RCD testing interrupt power?
Each RCD must briefly trip to confirm correct operation. We coordinate testing with site teams to ensure controlled, minimal impact on protected circuits.
Will documentation be suitable for insurers and audits?
Yes. All testing is completed to NICEIC standards with clear certification suitable for compliance audits, insurers, and internal records.
Do you carry out remedial works if defects are identified?
Yes. Where faults or non-compliances are identified, we can complete corrective works efficiently, re-test affected circuits, and issue updated certification.
Ensure every protective device on your site is verified, documented, and compliant.
