Under OSHA standards, what is the minimum bond size between the suspension strand and the existing ground?

The minimum bond size between the suspension strand and the existing ground is specified as No. 6 AWG copper according to OSHA standards. This gauge of wire is necessary to ensure proper grounding, which is critical for safety in electrical installations. A No. 6 AWG copper bond provides adequate conductivity and can effectively handle fault currents, reducing the risk of electrical hazards. It is designed to minimize voltage drop and help ensure that equipment is properly grounded, thus providing a reliable pathway for electrical faults to ensure the safety of workers and the equipment in industrial settings. Using a bond size smaller than No. 6 AWG could compromise the effectiveness of the grounding system, leading to unsafe conditions in the workplace.
