What is rccb?
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the electric currents not balanced between the energized conductor and the return neutral conductor.
Where is connect input in rccb?
An RCCB has 4 electrical connections.If you look at the circuit picture of the device (usually on the front) you will see that these 4 connections are split into 2 live/hot connections and 2 neutral connections. Furthermore they are divided again so 1 live on top, 1 live on the bottom, and also 1 neutral on top 1 neutral on the bottom.Electrically the device will function regardless of which side is used as the input.Which side (top or bottom) you choose to supply the device from is up to you and usually decided by the ease of access to the terminals at the time of connection.You may also consider from the point of using a busbar that it may be easier to mount the device on top of it (thereby feeding the device from the bottom), this is perfectly OK.From a strictly technical standpoint the armature (the moving part) of a switch should not be live/hot if the switch is in the off position, however from a practical viewpoint (since the device works regardless of polarity) this is usually disregarded in lieu of mounting and wiring ease with respect to RCCBs, MCBs etc.Summing up: As long as your supply cables (Live and neutral) are on one side (top or bottom) and your feed cables are on the other side you will not have any problems with the functioning of this device.Lastly,if in doubt, please contact an electrician.
