As a power systems analysis consultant we regularly get asked to carry out arc flash studies. We are always happy to do them, as it is a useful exercise in most cases. However, what we often see are clients asking for arc flash studies that are are not relevant or required. We have seen no end of arc flash reports that have pages and pages of meaningless tables and results.

We have put together a list of some common misconceptions and misunderstandings that we hope you find useful!
