FAULT CURRENT CALCULATION

The answer IS valid thank you very much (another GA for you). This is not a forum for answering peoples homework questions, nor is it a forum where information is given out to people who are trying to do something that they are clearly not qualified to do.

I would have written the same thing (and have done so on many occasions), except would have included a request that the original poster please explain WHY they are asking the question, so that we may discover the actual nature of the question.

As professionals it is our responsibility to ensure that the information is not only accurate and precise, but is also not going to be used irresponsibly by others (like answering someones homework questions or helping an unqualified person to further endanger the public). Something to think about, and before you jump to any further conclusions perhaps you should look at sb's previous posts before you politely tell him to "go away" for wasting peoples time.

Mr Sharma,

There is a reason why 'sb' was so much irritated to give such a reply . He is right in answering so and I give GA to him .

If you read the way the original thread is made , what any one will feel about it, is that , it is an examination question and the person who initiated the thread did not even bother to study the subject and ask certain question. He is not polite in using his language and he demand reply from members as if he is trying to test the technical competence of members. Do you think the members here are his paid employees to reply his examination questions . CR4 is not a site for that. Here members are to discuss about their technical doubts and help each other by mutual sharing of experience. No engineer is perfect in all fields even after many years of practically carrying out their job in the field as electrical engineering is so vast. To have doubt in any new area is understandable. But that does not mean that if a member raise his protest or anger seeing such an irritating thread he can be termed incompetent or arrogant .

In fact this thread does not deserve a reply as the subject need a through study and not the area of an amateur. It is an area that is most vital in electrical protection.When first I saw this thread I thought of replying, but decided otherwise as I thought of knowing the technical competence and knowledge of the person who raised the question. If he is an amateur he does not deserve a reply since only a competent qualified and authorised certified engineer is supposed to do this job.He must be competent otherwise , life of other people will be in danger. Hope you understand why 'sb' made that reply . Let the original owner of the thread come forward and tell his credentials so that a proper reply can be given, if he really deserve an answer.

Hope you will also join CR4 as a member and actively participate in discussions.

Regards

Sharma,

With an attitude like that you should take your own advise:-

"kindly do not open the cr4 link again"

Sapper.

Look who is talking.

A man who has not even joined the group is preaching. That too to a guy who is member for more than an year and has more than 30 good answers to his credit.

Join the forum man and then lets discuss this out rather than giving off the cuff remarks.

SB a GA from me as well.

Hope this helps.
