EWT - Grounding
- Prudently treat all lines and equipment as live – and as vulnerable to fault currents – unless s/he has verified that the equipment is correctly de-energized, tested for zero voltage, and grounded.
- Select protective ground equipment of appropriately high conductive capacity and low impedance, and verify that grounds are spaced at required minimum intervals.
- Safely connect and remove grounds (including specific scenarios for parallel and cable grounding).
The lesson covers establishing key conditions for safely working lines and equipment as "de-energized"; treating all lines and equipment as live, unless those key conditions are verified; anticipating and mitigating fault currents; correctly selecting and spacing protective grounding equipment; and safely connecting and removing grounds.
