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.

Residual current circuit breaker
How the rccb works?
An RCCB (Residual Current Circuit Breaker) works by constantly monitoring the current flow between the live and neutral wire. In normal operation with the two lines in balance the circuit works. If for any reason, even a small amount of imbalance in detected (as small as 30 milliamps) the breaker will trip in no more than 200 milliseconds. This is well within the limits of preventing both fire and bodily harm. Installation of these breakers is fast becoming mandatory around the world, especially on electrical circuits in areas prone to water (bathrooms, kitchens, etc...). It should be noted however, that if an impedance load (such as a motor) in introduced to a circuit protected by an RCCB there may be a problem with nuisance tripping of the breaker. So in most instances the bus bar in a breaker panel can be cut and the RCCB only installed on on side. This provides the protection required in areas where an RCCB is recommended, and allows standard breakers to be used in areas where the more expensive RCCB is not required or may affect equipment operation.
Full-adder using 4 X 1 multiplexer?
its simple......just you have to make truth table of input and output ......then u will notice that output column can be obtaining by just replacing it by third input or negation of it... in some cases output just hav to connect to one or zero input........for the corresponding output
Is PNP sourcing or sinking?
PNP is sourcing. NPN is sinking. You generally connect NPN to ground and your PLC(or any load)input. With PNP you connect to V+ and to your PLC. Your PLC (load) should have the same ground or V+. Sourcing (PNP) provides a path to +24DC generally. Sinking (NPN) provides a path to 0V DC.
What do you mean by crisp input value in fuzzy logic?
nonlinear or irregular input
Is an RCCB the same as a fuse?
no
What does rccb stand for?
RCCB stands for Residual Current Circuit Breaker. It is an electrical switch that automatically disconnects the circuit in case of a leakage current to prevent electric shocks and fire hazards.
Is a rear usb a input device?
A USB port is both and input and output port. Depends on what is connected to it as to which is functions as. Connect a camera and it is an input device. Connect a printer and it is an output device. Connect a printer/scanner and it is both.

How do you connect headset with two 3.5mm jack to one input 3.5mm jack I have laptop Lenovo G510 and there is only one input for headset sound and there is built-in microphone bad quality any help?
You cannot connect headset with a two 3.5mm jack with a one input 3.5mm jack. It is not made for a two jack connect.
