What must be monitored for cables connected to equipment to ensure they are within safe pressure limits?

Monitoring the pressure exerted at cable ends is crucial for ensuring that the cables remain within safe operational limits, especially in hazardous locations. Cables that are subjected to excessive pressure can experience damage, leading to insulation breakdown, conductor exposure, and potentially hazardous conditions such as electrical shorts or fires.

When cables are connected to equipment, it is important to assess the mechanical forces acting on them. Excessive pressure can arise from various sources, such as improper installation, environmental conditions, or physical obstructions. By continuously monitoring the pressure at the cable ends, operators can detect any pressures that exceed safe limits, allowing for timely intervention before a failure occurs.

Other options like temperature stability, load distribution, and vibration levels, while important in their own right, do not specifically address the critical aspect of pressure at cable ends. Failure to monitor this pressure can lead to catastrophic equipment failure or create unsafe conditions in areas designated as hazardous. Thus, monitoring pressure is a primary safety concern in the context of hazardous environments where cables are utilized.
