Ring and Radial Looping

Radial is not really a loop. Where there is wire there should be a breaker. If in doubt check the code. Has the wire changed. Do a search on breakers. It will help with the homework.

abuee,

You need a lesson in professional ethics.

If, as you claim, you are an engineer: "I Mohammed Abueed, an engineer who works in the field of buildings consultant", your client probably thinks that you are competent to perform the task to hand. Clearly, you are not.

You've come here before, wanting the forum to do your work for you.

Good luck, I think that you should do your own work and consult the appropriate codes and regulations.

dear

I am a mechanical engineer and changed to the field of contracting. this issue was discussed at electrical department and some guys agreed that there will be a change of the main breaker but some resist that no need. so for curious to know this answer because our electrical guys assume to be professionals in there work. but the lecture you gave totally rejected and un-accepted nd shows how that much you are arrogant and unwilling to help others you can simply give hint or codes to use regarding this issue or you can keep your word in your mouth and be silent without giving instructions to others. if you consider yourself as a encyclopedia, keep your information to yourself and set far away from others to get any information as per target of this group.

regards

Before you start complaining go back and look at what you have posted here on CR4. You have mentioned none of this and not explained any of your reasons.

Are we expected to read your mind? We comment on what's given and what we perceive based on the limited information. I posted the same thing as an answer to you as did others, the information provided by you previously dictated our response.

Now, with so little information provided and no standards or even country mentioned we still can provide no answer as to why your electrical guys don't agree with whatever standards and building codes they are working to (they vary from country to country and site to site by the way).

Have you considered just asking them?

dear

I agree with you that i didn't mention complete details for the case but it would better if you asked about details or prefer not to answer keeping in mind that i am not professional as you in this field but the knowledge in the issue is better than not.

Anyway, what i understood is that there is something not related to country standard but its considered as electrical basic which is extra devices related to earthing in main breaker should be added to be suitable for ring loop after changed from the radial one.

regards

You have been on CR4 long enough to know (if you have been viewing regularly) that we get plenty of homework questions and people asking us to unethically do their job for them, we don't take kindly to unethical behaviour hence some of the comments.

Your going to have to provide us more on the standards involved as they vary and so do earthing requirements (there are a number of different earthing schemes world wide and they effect what is and isn't allowed). What country is this in?

Can you explain the question in more detail again and at the very least provide the country it is in.

You are a building consultant.

That means that your client is paying you because they think (for whatever reason) that you are a knowledgeable engineer.

Every time you have come here has been to ask the forum to do your work for you. I remind you that that is the work for which YOU are being paid, not the forum.

You have an obligation to your client to know the answers yourself or pay a professional who is then affirming that they are competent in their field.

Asking an anonymous forum for answers that may have life safety implications is not the way to conduct business.

dear

don't talk too much to shine yourself here. also, as the proverb said " don't give me fish but just learn me how to hunt" just give ref. to read or just keep silent without accusing others

regards

Look if you want an answer spend more time explaining your question better and adding important information we have requested and less time being defensive.

Assuming that you are on planet Earth, even you should be able to locate the applicable electrical codes for the project. If not, you are unfit to be on this job and should resign!

Seems to me that you are the arrogant one here.

Yes (probably).

Refer to the applicable standards you are already working to, as Lyn has said already it's your job and your being paid to know.

Refer BS for ring and radial circuits for socket outlets which gives no of sockets in each circuit,CB size and wire size as well as floor area. It may be applicable to buildings but not sure whether applicable to industries like Garment factories where each sewing machine is connected to socket outlet in radial circuit consisting of many sockets. I wonder whether BS has separate regulations for industry other than BS7671.

So, these people, the ones who are arguing, do they work to any national electrical standards at all, or is it all make it up as you go and double check it with a bunch of anonymous geeks on the internet just to make sure? And you're actually charging for this? Ye gods!
