What is the minimum resistance required for personnel ground straps?

The minimum resistance required for personnel ground straps is set at 250,000 ohms. This requirement is established to ensure adequate grounding and static electricity discharge, which is critical in aviation and aerospace environments where sensitive electronic equipment is used. High resistance values protect personnel from electric shock and mitigate the risk of damaging electronic components during operations. Ground straps must effectively allow static electricity to flow to the ground without permitting excess current, which could lead to dangerous conditions. A specified minimum resistance level helps maintain a safe environment by ensuring that ground straps are both effective and reliable for personnel working in proximity to aircraft and other equipment.
