Authentic User Feedback

🔌 Residential Electrical Installer Reviews

⭐⭐⭐⭐⭐ James Peterson - Licensed Electrician
"Installed the Onesto RCD05 Base Model in a family home last April, and it’s been flawless. The 30mA sensitivity trips precisely when needed—caught a minor fault in the bathroom circuit during testing. Double pole design gives me confidence in full circuit disconnection. A solid, code-compliant choice for modern homes."

🏭 Industrial Maintenance Engineer Reviews

⭐⭐⭐⭐⭐ Elena Vasquez - Facility Maintenance Manager
"We upgraded our workshop panels with the Pro Model of the Onesto RCD05, and the difference is noticeable. In high-load environments with mixed AC/DC equipment (including solar inverters), the Type B detection capability is essential. No nuisance tripping, even under variable loads. The fast response time likely prevented a potential fire incident last month."

Purchase Date: February 2025 | Usage Period: 4 months

🏢 Commercial Building Contractor Reviews

⭐⭐⭐⭐☆ David Lin - Electrical Contractor
"Used the Advanced Model across three office renovations. The enhanced durability and faster response are worth the premium. Installation was straightforward, and compliance with IEC 61008 made inspections easy. Only downside: slightly bulkier than older models, so panel space planning is crucial."

Purchase Date: November 2024 | Usage Period: 6 months

🌞 Solar Installation Specialist Reviews

⭐⭐⭐⭐⭐ Priya Nair - Renewable Energy Technician
"Type B RCDs are non-negotiable for solar setups, and the Onesto RCD05 delivers. Installed the Base Model in a residential PV system, and it handles DC leakage currents reliably. The chemical-resistant housing is a plus in outdoor enclosures exposed to UV and moisture. Peace of mind for both installer and homeowner."

Purchase Date: June 2024 | Usage Period: 10 months

🏠 Home Safety Enthusiast Reviews

⭐⭐⭐⭐☆ Tom Reynolds - DIY Homeowner
"I’m not an electrician, but I upgraded my main panel with the help of a pro. Chose the Onesto RCD05 for its safety reputation and Type B certification. The unit is well-built, and the status indicator is clear. Only wish the manual had more beginner-friendly diagrams. Otherwise, excellent protection for a modern home with EV chargers and solar."
