3/19/2024 0 Comments What is the arc flash boundaryJust like the incident energy distance, the limited and restricted approach boundaries should be on your arc flash labels. Limited approach boundary is not directly tied to the incident energy level but rather to the voltage of the panel upstream, example 600V is a 3ft and 6inch electrical limited approach boundary. Looking to get arc flash labels on your equipment? Contact us for more details. Having a detailed arc flash label on your equipment will spell out exactly what your arc flash boundary working distance is, ensuring you have the proper space to protect from arc flash. Standing outside of the arc flash protection boundary will ensure that you are not exposed. So, does the incident energy have a direct effect on the arc flash boundary distance? Yes! As mentioned above, arc flash distances are increased when dealing with higher incident energy value due to the increased risk of receiving 2nd-degree burns if exposed to an arc flash. So, instead of changing how far away this distance really is the term protection was dropped and now we have the arc flash boundary. The reason this was selected is because that is what is considered the survivable level… not the most comfortable level. This boundary (or invisible barrier) is the distance away from a potential arc flash hazard that someone would receive 2nd-degree burns if exposed to an arc flash. Originally this was referred to as the arc flash protection boundary… until someone realized it didn’t offer much protection. FREE DOWNLOAD: DEFINITIVE GUIDE TO AF STUDIES
