Rcds and rcbos
WebFirstly fuses and MCBs – that is miniature circuit breakers – they both ‘blow’ when current is exceeded, but an MCB can be reset after the fault is fixed, a fuse must be replaced. A fuse is basically a piece of wire between two contacts to make a circuit. When current flows heat is produced and the wire gets hot.

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. 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.
WebOct 21, 2024 · These types of RCDs protect the circuit from overload, as well as earth leakage faults; therefore called an RCBO. What’s the difference between a Residential and a Commercial RCD?
