During periods of ground fault, loose couplings and connectors in metal conduit systems can cause a fire hazard. Is this statement true or false?

The statement is true. Ground faults can lead to unwanted current flow that may not be properly managed if there are loose couplings and connectors within metal conduit systems. When these couplings and connectors are loose, it creates the potential for arcing or sparking, which can generate heat. If this heat builds up enough, it can ignite surrounding materials, thereby posing a fire hazard.

In metal conduit systems, proper bonding and grounding are essential to ensure safety during electrical faults. The loose connections can disrupt the integrity of the grounding system, increasing the risk of fire, especially if the system is subjected to ground fault conditions. Therefore, the maintenance of tight, secure connections in such systems is vital for preventing electrical hazards, including fires, particularly during faults.
