I would say the short answer is "yes". The voltage range you are talking about is within the bounds of IEEE 1584. What is the specific utilization voltage you are using?

Even if it uses the DGUV 203-077 method for arc flash calculation, the method is applicable over 50V; so the calculation should have been done. It may depend on the electrical safety standards of the exact country you are talking about.

In Europe, arc flash studies typically cover equipment operating above 208 volts. The range you mentioned (208-240 volts) should indeed be included in the study. Standards like IEC 61482 provide guidelines. Make sure all relevant equipment and voltage ranges are considered for safety assessments.

Yes, an arc flash study is required for equipment operating between 208V and 240V, but whether the study must cover these voltages depends on several factors, including standards and local regulations.

Hello. I am wondering why arc flash studies in Europe usually focus on equipment operating above 208 volts and why the 208-240 volt voltage range needs to be included in the studies?

208VAC three phase with short circuit current greater than 2000A. Not required for single phase 240VAC.
