In hazardous (classified) locations, where is the bonding means required to be installed?

In hazardous locations, bonding means is required to be installed from the hazardous location to the service equipment to ensure safety and compliance with electrical codes. This practice is critical because it helps to mitigate the risk of static electricity, electrical faults, and potential ignition sources in environments where flammable gases, vapors, or dust may be present. By bonding the hazardous location to the service equipment, any electrical faults can be safely cleared through a low-resistance path back to the ground, reducing the likelihood of sparks that could ignite combustible materials.

Establishing a reliable bond between the hazardous area and the service equipment helps maintain a controlled and safe environment. It ensures that any dangerous electrical buildup is effectively managed and prevents the accumulation of static charges which can pose significant risks in such environments.
