WebDec 1, 2024 · RCD vs RCBO. RCDs are designed to protect against electrocution or electrical fires by cutting off the power supply whenever current leakage is detected. They accomplish this by continuously monitoring the current levels going through a wire in both directions. The circuit is automatically broken in case there’s a difference of 300mA or less. WebRCDs work by monitoring the live and neutral wires by passing them both through what is a small current transformer. If everything is OK the current in on the live wire returns on the neutral and cancels out exactly resulting in a sum of zero.
