Clip-On Ammeter testing, does it count as voltage-testing?

Our worksite is currently in the process of going through an arc-flash study to determine hazard levels.  However, in the meantime, we are utilizing the NFPA guidelines as provided by the Canadian Workplace Electrical Safety Guide, (Z462-12).  For this we are using Table 4A, the Hazard/Risk Category Classifications table, to determine our hazard ratings for equipment, however we were questioned about clip-on testing.  The equipment in question requires a cover to be removed to access the conductors, however the conductors are insulated, and the terminals and relays are guarded.  Does this still qualify as a level 2 hazard as indicated by the table when concerning voltage testing, or is it considered a lower hazard as there is no contact being made to the terminals?
