Is it true that iron wire can be used as an equipment bonding jumper?

Iron wire is not suitable as an equipment bonding jumper because it can corrode over time, especially in environments where moisture or chemicals are present. Bonding jumpers are specifically used to ensure electrical continuity and the proper grounding of equipment; therefore, they need to maintain their conductive properties over an extended period without degrading.

Using conductive materials like copper or aluminum ensures reliable performance and long-term durability. While there may be temporary setups in which iron wire might be utilized, the standard practice dictates the use of materials that are more resistant to corrosion and degradation. Similarly, the requirement for insulation highlights that equipment bonding jumpers should maintain their conductive properties without risk of damage or reduced effectiveness over time. Thus, the claim that iron wire can serve this purpose is not aligned with established electrical safety standards.
