How many cross ties should be provided on a multiple row circuit?

• A. At least 1 path
• B. At least 2 paths
• C. At least 3 paths
• D. At least 4 paths

Answer: (B)

The reasoning for requiring at least two paths in a multiple row circuit is based on the importance of redundancy and safety in electrical systems. In mining and other industrial environments, having multiple paths ensures that if one path fails or becomes compromised, an alternative route is available to maintain the integrity of the circuit. Two paths are crucial for reliable operation, allowing for continued functionality and reducing the risk of complete circuit failure. This redundancy also helps in maintenance situations, where one path can be taken offline for repairs without disrupting the entire system. Therefore, establishing at least two cross ties is a best practice in circuit design, particularly in settings where safety and operational continuity are paramount.
