Trailering cables and power cable connections shall not be broken under load. True or False?

Trailering cables and power cable connections shall not be broken under load. True or False?

• A. True
• B. False
• C. Not specified
• D. Sometimes

Answer: (A)

Under load means when the equipment is energized and may be pulling or carrying a load. Trailering cables and power cable connections must not break under that strain because a break can expose live conductors, cause shocks, arcs, fires, or power loss, all of which create serious safety hazards in a mine setting. To prevent this, these cables and their connections are designed and maintained with adequate insulation, strain relief, and connectors rated for the expected electrical and mechanical stresses, and they are inspected regularly. If a cable or connection were to break under load, it would compromise safety and reliability, which is why this rule is stated as true.
