Single Phase Arc Flash Label Requirements
(OP)
Based on the latest NFPA 70E and other latest references/guidelines are single phase panels in industrial facilities required to have arc flash labels?

Incident energy levels do not determine whether or not a specific device will get a label or not. If a device requires a label you would calculate the incident energy level to determine necessary PPE category, arc flash boundary, and etc.
My question is do these panels require labels, or is there some sort of exemption, as this will determine whether or not I will model them for inclusion in the study. I can not find anything stating clearly yes or no or even if a generic label would suffice but it is something that will play a large part of a project as the time to model and label these additional panels can become quite extensive in an industrial setting.
The 2012 edition stated an exemption for certain cases but the 2015 version does not in regards to label requirements it just list types of equipment in article 130.5(d).

So should we label everything that needs inpection?... My opinion is yes but is there a standard in place that calculates single phase and lower voltages?

ETAP gave the same reference to using IEEE 3 phase for conservative results and then tried to sell me on the single phase module but cant reference where single phase is actually required.
