What additional safety measure is required for underground installations?

The installation of underground electrical systems often requires protective measures against potential hazards such as moisture, mechanical damage, and environmental exposure. The use of protective raceways is a significant safety measure because these conduits shield electrical wires and cables from physical damage and help prevent moisture infiltration, which can lead to electrical failures or hazards such as short circuits or electrocution.

These raceways provide a secure environment for the wiring, ensuring that the conductors are properly insulated and protected from the surrounding soil and underground conditions. By installing wiring within protective raceways, it not only enhances the longevity and performance of the electrical system but also complies with established regulations and standards that govern underground installations. This measure is crucial for maintaining safety and reliability in such environments.
