What is the function of the overcurrent device regarding LFMC?

• A. To maintain proper voltage
• B. To limit the current to 60A or less
• C. To enhance flexibility
• D. To prevent bonding

Answer: (B)

The function of the overcurrent device in relation to Liquid-tight Flexible Metallic Conduit (LFMC) is primarily to protect the conductors within the conduit by limiting the current that can flow through them, specifically to a rating such as 60A or less. This is critical because excessive current can lead to overheating, which poses a risk of fire and equipment damage. The overcurrent protection device, such as a circuit breaker or fuse, serves as a safety mechanism that interrupts the electrical flow when it exceeds the set limit, ensuring that the conductors do not carry more current than they can safely handle. While maintaining proper voltage, enhancing flexibility, and preventing bonding may be relevant considerations in electrical installations involving LFMC, they are not the primary roles of the overcurrent device. The focus of the overcurrent protection is solely on managing current levels to ensure safe operation.
