An RCBO protects Electrical equipment against 2 types of faults. Residual current and over current. Residual current. or earth leakage as it is sometimes referred to, occurs when there is a break in the circuit which can be caused by faulty electrical wiring or if the wire is accidentally cut. When there is a break in the circuit which may be due to faulty electrical wiring or accidental cutting of the wire. To prevent the current from being redirected and causing an electric shock. the RCBO current breaker stops it.

A timer is a type of time-switching device that controls and controls Electrical circuits and electrical and electronic devices through time setting (on/off). The timer is basically 8-pin. Like other controlling devices the timer has a coil and when this coil is magnetized, the timer works on/off. The timer has 2 common ends and each common end has normally close and normally open options. When the timer is set by time, the timer trips at the end of that time and turns the common is normally closed (on) to open (off) and normally open (off) to close (on). This is how the timer works.

CFL stands for Compact Fluorescent Lamp which is an improved version of tube lights of earlier days. Like tube lights, it is a vacuum glass tube with fluorescent powder coating which is not as long and straight as tube lights but curved/twisted compact, or small in size. Like a tube light, it has electrodes or filaments at both ends. But in this case, instead of a choke, there is an electronic circuit that drives the Compact Fluorescent Lamp. Because the red wave is less in the light of the Tubelight and Compact Fluorescent Lamp, the object looks a little pale or the correct color of the object does not appear.
