circuit under some of the following conditions, EXCEPT for: - ANSWER ✓
The isolation can be operated from the ground directly at the base of a
structure.
3. Isolation and tagging (no locks) is acceptable for an overhead distribution
circuit under some of the following conditions: - ANSWER ✓ 1. The
isolation point is a physical and visual like a line cut or riser removed.
2. The isolation point can only be operated by the operating authority or
qualified worker.
