What is meant by stalling of motor?

Stalling is a condition at which a motor stops rotating even when there is sufficient voltage at it’s terminals. This condition occurs when the torque required by the load is more than the maximum torque (Breakdown torque) that can be generated by the motor. At this condition, the motor drains the maximum current and the speed comes zero.

Difference between RCCB and RCBO

RCCBs and RCBO are residual current protection devices. Residual current protection is achieved by monitoring the flow of current in the line and neutral. In a healthy circuit, the current flow through the line will be equal to the return flow in the neutral. In the case of any abnormalities, this return flow may not be equal to the current flow in the line. Residual current devices sense such scenarios and interrupt the circuit.
