Does any one have specifications they have used for the periodic analysis reviews that are required by 70E article 130.5. Or, if you don't have specifications, do you have a suggestion for what should be included in these reviews?
Thanks
We have treated the arc flash study review much like a short circuit / coordination study. At our sites if there are major changes i.e. new additions, new major equipment, we will go back and revisit the study. Otherwise we go back for a complete study review every 5 years or so. (sometimes a little longer

)
When we review our studies, we just check the data to see if any device settings were changed, utility data changes etc. If no changes were made, we just reconfirm the existing study. If a few changes were made, we revise the data base and rerun the study to see if it had a significant affect on the results.
I can see a problem if an older study just had minimal info on the arc flash labels. They would need to brought up to the latest requirements. Our labels have all the info and then some, so this is not a problem.
