Which statement best describes the required relationship between EPP III and ECS/RS when considering hazard reduction?

• A. Position at the maximum distance allowed by cable lengths and terrain
• B. Position as close as possible to ECS
• C. Position without regard to terrain
• D. Position at a fixed distance regardless of cable length

Answer: (A)

The key idea is hazard reduction through maximum practical separation. To protect people and equipment, EPP III and ECS/RS should be spaced as far apart as feasible within the limits of the cable lengths and the terrain. Extending the distance increases clearance, limits the potential impact of faults to a smaller area, and makes safe maintenance access easier, while still allowing the required connections to be made. If you place them closer to ECS, or ignore terrain constraints, you raise the risk and potentially create unsafe routing or unnecessary exposure. A fixed distance that ignores actual cable length and terrain doesn’t reflect real-world feasibility and can undermine safety and functionality.
