What is the primary function of the ground cone in LFMC fittings?

The primary function of the ground cone in LFMC (Liquid-tight Flexible Metal Conduit) fittings is to ensure effective grounding and bonding of the conduit system. This is crucial for electrical safety, as it provides a path for fault current to flow safely to the ground, minimizing the risk of electric shock or fire. The ground cone ensures that the metal conduit is securely connected to the grounding system, which is necessary for both compliance with electrical codes and the overall protection of equipment and personnel.

While LFMC fittings serve other purposes, such as supporting the conduit and preventing water ingress, the grounding and bonding function is fundamental. This grounding capability is particularly important in environments where electrical faults could pose serious risks, making it vital to maintain a reliable ground connection throughout the conduit system to safeguard against potential hazards.
