- What is the RCCB circuit breaker working principle & how does residual current RCCB trip work explained in the video tutorial. A residual current circuit breaker (full form of the RCCB) or residual current device (RCD) is a current sensing electro-mechanical device that breaks an electric circuit in case of a fault. It operated, whenever the difference between line and neutral current (called residual current) becomes more than the set value. It is an electrical shock protection device for safety at home. What is the RCCB circuit breaker used for human safety from electrical shock, RCD residual current device is explained. RCCB types AB, A & B and also poles; test method for trip action is explained in the lecture. ELCB Earth leakage circuit breaker explained in electrical engineering lecture. Educational video tutorial 145 by G K Agrawal.

Wow, this explanation help me a lot. Thank u sir.
Very clear explanation, anybody can understand.
Thanks sir
Comments welcome
Excellent. Easily understandable to anyone.
thats what i was looking for. how opposite magnetic flow through core cancel each other and thus do not induce current into secondary wire
Wonderfully explained sir ❤
Thank you for your guidance very Helpful
I found it very difficult to understand what you're saying, but extremely easy to understand what you're showing!
Thank you for this very helpful video.
CC subtitle is written in English in video. You can read that. you have to enable that.
This is the greatest content, thanks sir
Good information
Sir, what happen to the electricity in final circuit when the RCCB trip??
Thank you sir,for your clear explanation
Excellent explanation sir....
Wiseman
I like your explanation. Very detail. It make me understand easily.
Hope that u can share video in english much more. Coz it’s hard for me watching your video in india language
My many videos are in English version also, many times with CC in English also. If no English version, then I will write CC in English. If it is advance topic then it is sure to be in English version also.
You are legend
Respect to this simplicity of explanation not like University teachers they made things completely out of the world
one que agar kisine line wire ko touch kar liya aur usne chappal pehni ho to rccb kam karega. second que gar me rccb lagane ke bad line aur neu ke sath ear wiring kare ya nahi.please video banaye sir thanks
RCCB chappal ko nahee janta hai. Agar 30 mAmp leakage hogee, tho trip karega. Ab chappl kasee hai, uska resistnce kitna hai. Industry me Special shoo pahenna jarooree hota hai. Aur rubber pad bhee dhartee per pade raheta hai.
Thanks Sir, this explanation help a lot. Type B ELCB is that suitable for pure DC network?
sir,ur good electrical traner (firoj Alam,soudiarabia)
Sir is it rccb trip on short circuit phase and nutral? Pls reply
No, it will trip due to leakage current between line and earth. Please watch video again
@@GKAgrawal2 thank you so much sir
Very elaborate explanation
Great sir... keep it up...😊
Good explanations tike bay.if someone touch .it will trip .
Is there any electronic circuit inside of control circuit to amplify current ?
Thanks a lot for this useful lesson sir jee.
So clearly .Thank you
sir ji a doubt- ELCB and RCCB are same. ELCB is called so ,because it trips on earth leakage.i.e. the name due to its function.
RCCB is called so,that it is working on the principle of residual current inside the breaker circuit. AM I CORRECT Sir? So many people are asking question the difference between ELCB and RCCB.
You are right. Both are same object wise. ELCB was used olden days. RCCB is used now days. Now ELCB may be used in very specialized application in industry only. ELCB uses ground wire to measure current. So ELCB may not be able to measure the current flowing in human body during shock as this current does not flow in the ground wire. while RCCB can measure current in body during shock also. Above explanation is based on my understanding. Now day lot of electronic based protection are used in industry, and they are defined based on various protection requirement. These electronic based relay may not use the gender name RCCB or ELCB ( they are not interested in name but in function only). Protection and monitoring panels are designed to protect the equipment in quite complex way. but we do not use RCCB or ELCB wordings.
thank you sir
Thank you ❤
Why 2Poles dont hv 2 switches. Or 4 poles hv 4 switches.. used for shutoff
They do have 3 or 4 switches, but they are mechnically joint together to make all 2 or 4 switches Operation at a time.
Hi, for a condition, Will RCCB trip if a person touch both-line(phase) wire and neutral wire together with both the hands?
so sir, what will happen if we have leakage at the Neutral conductor and we touch this conductor? ( is it working familiar with leakage at the Live conductor?
RCCB will trip in case of leakage in neutral also.
@@GKAgrawal2 and if I change the load side of RCCB with deals as below:
L(RCCB load side ) is connected to N(Load)
N(RCCB load side) is connected to L (Load)
is it still working fine?
In case, I see the first time, I connect L( load side of RCCB) to L(Load) and N(Load side of RCCB) to N(load) then it was not trip but when I changed it like that I described above and then it was trip.
So could you explain to me this situation?
Thank you so much
Your load one wire may be leaking. When the particular wire gets connected to the line, then leakage will become more.
@@GKAgrawal2 thank you so much
Thank you. I have one question. Whether RCCB trips if there is a sudden fault at input side of RCCB? Say phase to ground fault at the input of the RCCB, then also there is possibility of transient residual current through RCCB?? Please give your opinion on this.
Sir, you teaching method is Awesome.
Thanks.

Sir when power off and on the RCCB is tripping.
no, it will not trip.
Ur explanation is awesome 👏💐. Thank you so much 🙏
For what applications is it a must to use either type B or type A RCCB?
What is the meaning of RCD CURRENT rating?
Thanks from Bangladesh
what will happen if reverse connection is given
Sir, Very Good Tutorial .. Commendable. However, I don't know, why you didn't elaborate on Type B & the applications for it. As per regulatory standards - what type should be used where ?? if you could add, will be nice, in my opinion.
Voltage between neutral and earth, in early morning is 10 to 18 volts, in afternoon 8 to 10 volts, in evening 10 to 15 volts. In early morning if I start /run, 2kw water heater or 1HP bore jet pump or both, RCCB(32A/30ma, Havells) of my house trips. If I run both load in afternoon or at night, RCCB donot trip. What is the problem.
Then what you did after?

Thanks brother.. for your explanation.. very helpful for us.
Pl note that I am Senior citizen.
thank you very much sir
Excellent
Thanks

is it okay to use in line to line connection
See breaker data sheet, different type of breakers may be available.
Sir, Where to install RCCB before oscillator or after oscillator switch . in home, where 3 phase domestic current .
Where is the oscillator, where is 3 phase current in homes in oscillator ?
Sir, In the main board DP Box 3 phase Power supply in home, it is having Legrand-63-Amp-4-Pole-Isolator is there, for safety where i have connect RCCB 63 amps install it
rk sona Hi, you can install it in two ways.
1. Install a 4 pole RCCB on mainline coming out of isolator.
2. Install 3 single phase (2 pole) RCCBs, one one each phase after isolator.
First method is good if you have a 440 volt usage such as 3 phase motor.
Second method is good when you have divided load across 3 phases. It will trip only that portion of load which has leakage.
can we use rcd in home without ground earthing connection means supply only 2 wire in entire home
RCCB require only line and neutral wire, so it will work and trip during earth fault. However earth wire is required for safety. Watch importance of earth at th-cam.com/video/Vl3tvO51RTI/w-d-xo.html
Wrong analogy.
There can't be a current flow in neutral wire, unless it is an unbalanced circuit.
Name itself is saying neutral means zero voltage. There can never be a current with zero voltage.
Since no current in neutral you Don feel shock in practice.
I welcome everyone's Comments
Current flows when there is potential difference occurs...so phase to neutral current flows
