In environments where explosive materials are present, the grounding of electrical equipment is a critical safety measure. These environments, classified as hazardous locations, often contain flammable gases, vapors, or dust, which, when exposed to electrical sparks or faults, can cause explosions. Proper grounding of electrical equipment is essential to prevent the accumulation of static electricity,
