YOUR TEXT DISPLY IS COVERING (COMES OVER) THE DIAGRAM . THANKS FOR EXPLANATION . WHY THERE IS 2 RINGDS SHOWN FOR CORE BALANCE CT .? SINCE BOTH PRIMARY AND SECONDARY WINDINS ARE ON BOTH THE RINGS ??
Elcb mai earth conection ka terminal rahta hai jaha se earth in hoke out hokar sabhi equipement mai conect hota hai jabki rccb mai earth ka conection nahi hota hai earth ka conection sedhe equipement se hota hai
My question: if I use the RCCB and change the sequence of the connection( L(RCCB) connected to N of load and N(RCCB) connected to L (Load), So what will happen? is it still working fine and detecting the leakage current?
ELCB comes in both voltage ELCB and current ELCB based on voltage and current sensing respectively. But the sensing phenomena is same and that is from the earth connection
Hi Sir, I have a 48V battery operated equipment. This equipment has a metal enclosure and is not connected to Earth. Can I use an ELCB to protect against shock hazard?
hi sir, you earned new subscriber. thanks for sharing. i have a few question. 1) why ELCB using 50V to trigger tripping? 2) for ELCB if any personal touch live part, current will pass through the personal only and not going to the earthing. This means no protection for people at all? so this ELCB only operate if live part touch the earth part? correct my understanding sir.
1.The ELCB (Earth Leakage Circuit Breaker) is typically set to operate at voltages higher than 50V for AC (alternating current) and 120V for DC (direct current) before it triggers. 2.If a person touches the live wire, the ELCB might not trip immediately because the circuit is open, and the current may not directly flow to the ground if you're not in contact with earth. thank for seen.🥰
ELCB has P and N terminal and how earth connection is made to ELCB In the diagram u show earth connected to ELCB .Is there separate terminal in ELCB for earth connection? It seems that earth is connected to load
Leakage current only flows where there is some leakage in the electrical network . Not every equipment has. But mostly it refers to the fault current which is undetected from breaker thats why we use these leakage breakers
Obviously the main thing that trigger tge protection is leakage current flowing in earth link. But voltage sensing means as the magnitude of leakage current is increases such that voltage across the tripping coil increased to 50v it trips the circuit
Now I clearly understand thanks to animation
Thank you very much. You explained very clearly. Now you cleared my doubts. Thank you again.

Very good. Thanks 👍
U welcome. Stay tuned and don't forget to subscribe
Thank you sir 👍🏻
Thank you for the clear explanation. Does it matter if the input and output connections are swapped?
it does
most important is the RCD or RCCB protects humans ...... and ELCB needs earth connection to work
Yes true
in one line if you have earthing, use elcb. otherwise use rccb,
i personally like rccb. it prevents from any electric shock
YOUR TEXT DISPLY IS COVERING (COMES OVER) THE DIAGRAM . THANKS FOR EXPLANATION . WHY THERE IS 2 RINGDS SHOWN FOR CORE BALANCE CT .? SINCE BOTH PRIMARY AND SECONDARY WINDINS ARE ON BOTH THE RINGS ??
2 rings only represent core. And i ll move the text
Tell please how to distinguish between them. What features have labels on their bodies?

My question: if I use the RCCB and change the sequence of the connection( L(RCCB) connected to N of load and N(RCCB) connected to L (Load), So what will happen? is it still working fine and detecting the leakage current?
i believe it will still work.

Hi. If ELCB is operated through the voltage, why the ratings shown as 40A/30mA?
ELCB comes in both voltage ELCB and current ELCB based on voltage and current sensing respectively. But the sensing phenomena is same and that is from the earth connection
@@electricallectures the thing is, you told in the video as the main difference between ELCB & RCCB is voltage and the current.
Hi Sir, I have a 48V battery operated equipment. This equipment has a metal enclosure and is not connected to Earth. Can I use an ELCB to protect against shock hazard?
Below 50v it's not required
Good
If I understand it correctly then on the Mains after MCB I should use RCCB then regular distribution breakers right?
yes
Good explanation
Thanks stay tuned and dont forget to subscribe
How many RCBs should I use? is just one enough for entire house?
If it's 3 phase supply... recommend to use each phase 1 no of rccb..
1 only
Excellent

Sir, in your experience, which company RCCB, give better performance sir. give me advice
Any branded company like schneider, abb, or any EU brand, koreon or japanese
Thank you sir🙏

ELCB has P and N terminal and how earth connection is made to ELCB In the diagram u show earth connected to ELCB .Is there separate terminal in ELCB for earth connection? It seems that earth is connected to load
VO-ELCB does have additional Terminations
to Earth Rods & to DFB E-Bar
could u show me the earth point in ELCB in any model?
Good, Kindly explain the meaning of Residual and Nuisance current
Residual current is the resultant of phase and neutral current . And nuisance tripping occur when unwanted tripping occur due to sensitivity
@@muhammadwaqas427 well explained 👍🏻
THANKS SIR.

So which one is better?
Obviously elcb has many advantages first it is more sensityve second earth connection is not required as in case of rccb
@@electricallectures Thanks for the explanation.
@@electricallectures 😵
rccb is better

Why does all equipment have leakage current?
Leakage current only flows where there is some leakage in the electrical network . Not every equipment has. But mostly it refers to the fault current which is undetected from breaker thats why we use these leakage breakers
Elcb, RCCB , design base is IEC 61008-2 according to this norms thease two working same principle e.g. earth leakage (current base)
Not voltage.
Obviously the main thing that trigger tge protection is leakage current flowing in earth link. But voltage sensing means as the magnitude of leakage current is increases such that voltage across the tripping coil increased to 50v it trips the circuit
@@electricallectures TRUE
This youtuber is talking abt VO-ELCB & you are on 61008

Nice videos but rcd is more sensible
Love it
