Capital Electrical Supply in Baltimore and Upper Marlboro, MD.
I'm the instructor.
It's a 5-hour class that can be used for DE or MD CEUs. I've actually applied for North Carolina because Capital has a store there, but they've yet to issue approval.
I use SKM Power Systems Analysis to show how the arc-flash calculations are performed and how a "maintenance switch" is used to reduce the incident energy while working on an energized system.
You'd leave qualified in determining what PPE is required for an application whether it's labelled or by using the 70E Categories method, as determined by a 30-question quiz at the end.
And as a point of emphasis to anyone using 70E, the latest edition has been issued. I think the date was June 1st, but that edition is now in effect. I've modified my classes to reflect the change because 70E is a National Consensus Standard and as such is in effect when issued. Judicial systems use the latest edition of a National Consensus Standard.
I'm surprised that the NFPA.org website offers classes on 70E and they use the 2021 edition. It's like they should have coordinated the issue update.
If you register for a class let me know who you are.
