How to wire RCBO in an AC circuit | air conditioner switch wiring

RCBOs function as MCB and RCD at the same time. we can use RCBOs to protect individual circuits instead of MCBs, or RCCD with MCB. mean while for economic reasons, a higher-rated RCBO Can be used as the main breaker to serve the whole wiring. In that case, the use of MCBs can not be overlooked because every individual circuit must be protected against the risk of overcurrent.
In this video the RCBO used is rated 63A so a 20A MCB was required to protect the air conditioner circuit against the risk of excess current.
