In accordance with NETA-ATS, what should be investigated if shield continuity test results exceed ____ per 1000 feet of cable?

For the question regarding shield continuity test results in accordance with NETA-ATS, the key threshold that triggers further investigation is 10 ohms per 1000 feet of cable. This indicates a level of resistance that could potentially compromise the effectiveness of the shield in safeguarding against electromagnetic interference and ensuring signal integrity in the cable.

Keeping the shield within acceptable resistance levels is critical for maintaining the performance and safety of the electrical system. A result exceeding 10 ohms suggests that the shielding is not providing adequate grounding or protection, which could lead to increased susceptibility to noise or disturbances in the signal carried by the cable.

Understanding the specifications provided in standards like NETA-ATS is essential for ensuring compliance and preventing issues that arise from poor shield performance. In this context, the selection of 10 ohms emphasizes the importance of maintaining a low-resistance connection in shielded cables to maximize functionality and safety in electrical installations.
