In this post I will explain, that why 30mA type RCCB breaker is used in the home and tripping time of the 30 mA RCCB. And if 30mA is not possible. Then how to use 300mA type RCCB breaker.
I will explain. where to use higher rating type RCCB breaker. Protection concept and as usual, I will share some extra knowledge as per my experience.

I discuss, an arc fault detection device (AFDD) or arc fault circuit interrupter (AFCI). You also learn some functions in AFCI AFDD breaker like flame formation, electric current signature sensor, algorithm concept of measurement, a block diagram of AFDD, causes of arc fault, and types of arc faults.

I will explain, AC or DC, which is more dangerous in this post. There are many factors that decide the intensity of electric shock on the human body. These other factors also play a very important role in addition to DC or dangerous AC frequency.
I will explain all these like AC or DC, which is more dangerous frequency to the human body in this post. Further, I also will discuss in detail the other factors affecting the intensity of electrical shock to the human body.
