My lift for G+3 floors ELCB which has 40A 300mA at home is tripping often in 3 phase. Lift company technician is telling us to increase it to 63A300mA. Whole house has 3 phase 9KW from the state electricity board. Any idea what may be the reason please?
Why you Wana improve power factor for your home? There are already capacitors installed in substation by power company for this. Do you want to help them? Or any specific reason?
What are you using in your house that would require you to start attempting power factor correction...? Large motors? Drives...? Transformers...? Welders...? Laser cutters...? X ray machines...? Perhaps you've got an induction melting & holding pot in the dining room...? Just asking...😒🇬🇧
Sir Mera set top box (GT Media andriod GTC) hy naya liya hy lekin koe b signal nahi le raha . even not taking local cable tv network. me ne buht se repair centres par dikaya hy lekin sab jawab dete hen k new hy android hy is ka nahi pata . so sir please help me. i can also send you in courier . please sir reply.
These devices are designed for lighting and house hold use where single phase power is used. Three phases acts like three single phases in house hold condition. So this explanation is valid.
This isn't "testing" an RCCB.... What happened to subjecting it to X1/2, X1 & X5... Then the same again at 180° of the waveform...? With thanks Glenn GLMelectrical...🇬🇧👍
Thank you...Excellent explanation 👌👌👌

If no supply is given but remove the neutral wire from any of the junction box can switch on the RCCB ?
Brother can use rccb as isolator is safe to use?
Yes sure
What if I have 3 phase and take current beetween 2 phases for example. Does the circuit breaker trip in this case?
No. As long you don't send current from any phase to ground earth after the elcb.
Where do you purchase it
Thank you!

क्या RCCB को 440V पर यूज्ड कर सकते हैं
You have explained only on single phase circuit not explained for three phase where phase current and neutral current are not same.

Hi
Is rccb is same as rcd.
In uk main supply from switch goes to rcd input and from output it goes to busbar then MCBs..
This isn't "testing" an RCCB....
What happened to subjecting it to X1/2, X1 & X5...
Then the same again at 180° of the waveform...?
