FAQ
Reader questions
Can this rcbo be used in a residential ongrid solar installation with a 80 A main supply?
Yes, the rcbo2p80a2way 80a 2p rcbo 100ma ac ongrid ln is designed for exactly this type of application, matching the 80 A main supply and providing 100 mA sensitive residual current protection for homes with solar integration.
How does the 100 mA trip sensitivity improve safety compared to higher settings? The 100 mA setting detects smaller leakage currents, which significantly reduce the risk of electric shock and fire compared to less sensitive devices, while still avoiding nuisance trips caused by normal capacitive currents in PV systems. What should I check if the rcbo trips frequently on my ongrid PV system?
Review load patterns for inrush currents, verify proper coordination with upstream devices, inspect wiring and insulation for faults, and confirm that the device settings match your installation requirements and standards.
Is polarity or phase rotation important when installing this 2 pole rcbo in an ongrid panel?
Yes, correct polarity at the input and neutral, plus proper phase connection for the AC side, is essential for accurate operation, reliable residual current sensing, and safe coordination with upstream protection.
