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
