In table 130.5(C) The task of "Application of temporary protective grounding equipment, after voltage test." is listed as a "Yes" for Likelihood of occurrence. Does this mean an EEW permit is required?
What document are you referring to? And what edition?

Thanks. I'm not a 70-E guy, but there are plenty in the forum who will answer.
In my past experience in an industrial setting, irregardless of voltage level, we always treated grounding cluster/equipment application as requiring a EEW. The EEW is required to voltage test, so while the PPE is on why not place the grounds. This practice could be debated based on the voltage level and type of circuit. We worked with everything from 120, 480 and 12,470 circuits. Especially with 12,470 circuits we theorized that a flash-over or lightning strike could accidentally energize the circuit while applying the ground. So to standardize safety procedures we used appropriate PPE and EEW for all testing/grounding jobs.
