Hi this is Steven Mill and today I want to tell you about my experience as an electrical engineer. That’s why I wrote this article which gathers 10 safety precautions you should take when you work on LV equipement.

electrical safety precautions

I have put together this article with an intention of providing some safety precautions to all those electricians and electrical engineers out there, who work on low voltage equipment regularly. Irrespective of the kind of experience you have in this field, I strongly suggest you to stay alert even when you are repairing the minutest of the faults, especially, when the electrical equipment is live.

Being an electrical engineer and having served in this field for over 10 years, I strongly recommend you to follow the below mentioned ten most important safety precautions that can help you keep away from electrical hazards.

Have you already shared your own calculation tool? And above all, are you ready to share it? This is the debate of the month that you could answer in this article. This month in our community we will introduce Gunther, a member who has written an article about arc flash for the blog some weeks ago. We also are going to ask you to help some members who have no answer to their topics launched in the forum. By the way you can also respond to Fred’s blog article “Schneider Electric sells products with fuses… LOL“. (more…)

This month in the community we have launched a survey about MV/LV transformer protection. We also published a blog article, about the US regulations regarding the protection of maintenance people, from the risks of Arc Flash named Arc Flash: are NFPA 70E and IEEE1584 dangerous? In the following article we will evoke some topics which have no answer in the forum and also introduce a member, Manh_hoa09 .

Arc Flash: are NFPA 70E and IEEE1584 dangerous?

My name is Günther Müller, I have 20 years of experience in electrical engineering, and I work for a Consultant in Germany. I currently work on the extension of the electrical installation of a site in Europe, owned by a large American industrial group.

In this context, we were asked to evaluate the risk related to Arc Flash, in compliance with NFPA 70E standard and the IEEE1584 calculation methodology. It was the first time I had to do this evaluation, as this is a US standard which I did not know about and which has no equivalent here.

First, we had to make the audit of the existing installation, and the dimensioning of the extension. Then, we had to make the estimation of the Arc Flash risk level for every electrical switchboard, in order then to choose the category of PPE (Personal Protection Equipment) which electrical maintenance people should wear when operating on or near these equipments.

But now I really wonder: will this really help to protect the maintenance operators against arc flash risks?
