What is the threshold for replacing temporary static bonding cables?

• A. One Quarter
• B. 1/3
• C. One Half
• D. Two Thirds

Answer: (B)

The main idea here is keeping bonding cables reliably capable of carrying current and maintaining a solid, safe bond during operations. Temporary static bonding cables are used to equalize electrical potential and prevent static sparks in environments with flammable or explosive atmospheres. Once the insulation or jacket shows wear that compromises safety, the cable should be replaced at the point where damage reaches about one third of its original condition. Why one third? When roughly a third of the insulation is worn, cracked, or exposed, the cable’s ability to resist arcing and to carry current safely is compromised. Replacing at this threshold preserves electrical integrity and reduces the risk of insulation failure or sparks during use. If you see visible damage such as cracks, cuts, frayed strands, melted spots, or exposed conductor, replace it immediately—the aim is to prevent any potential ignition source. In short, use the one-third wear threshold as the practical safety limit for replacing temporary static bonding cables.
