I am an electrical power engineer and arranged power system
for a data center, I installed MCB, ELCB and erthing system
TN-C-S.
But some times several ELCBs Disconnect circuits at the
same time! what may be the reason? (the ELCBs are 25A ,30mA)

Dear Mahdi
Some Current is leakege in earth form circuit and
equepment . so your ELCB was trip.so frist check the all
circuit .
you are using TN-C-S earthing .in this common earth use
for nutral and grounding .
I suggested you for use TN-S type earthing .

I want to put this query to SENIOR & EXPERIENCED ELECTRICAL ENGINEERS. 1)I want to know about the control circuit diagrams for control panels. I found it difficult to understand. Is there ant booklet through which we can learn the circuit diagrams? 2)I want to learn about conduiting, laying cables, preparing cable schedules and various techniques which is the part of building infrastucture(construction field). I don't have any experience in this area. I have experience in control panels only. that's why i am not getting any opening in building infrastucture (construction field).Can I get the job in this field as Trainee Engineer? How to enter this field? I need job in PUNE
