My company produces shelters for harsh environments. Normally the shelters have a 208/120V input however this project I am working on has a requirement for a 380V/220V. I am looking to hook a transformer to power the shelter for basic tests and verification and would like to ensure the risk of an arc flash is minimal. When I look at the 462 tables and decision diagram it looks like I would have to do an incident energy analysis. I found a few online calculators and have come up with an IE less than 1 cal/cm^2. Would someone be willing to do an informal check based on the attached diagram and run it through ETAP? We do not have a license for it since we would not use it enough. I would like to get something done informally and then take it to get a proper analysis done if there is discrepancy.
