What should be used to bond across a gate in a fence?

Using a buried bonding jumper to bond across a gate in a fence is crucial for maintaining electrical safety and integrity. A buried bonding jumper provides a reliable and secure connection between two separate systems or grounding points. It ensures that if there is a difference in electrical potential between the gate and the rest of the fence, the buried bonding jumper allows the current to safely flow, reducing the risk of shock or electrical fault.

This method is particularly important because gates often create a break in conductive surfaces that could otherwise be at the same electrical potential. By utilizing a buried bonding jumper, you can effectively reduce the risk of galvanic corrosion and maintain a continuous path for grounding, which is essential for protecting both personnel and equipment.

The other options are not suitable as they either do not provide a reliable electrical connection or can compromise safety. A loose wire lacks the necessary stability and reliability, conductive metal bars, while potentially effective, may not be proper for every installation and might not be as reliable as a bonded solution, and plastic ties do not conduct electricity, making them ineffective for bonding purposes. Thus, using a buried bonding jumper is the correct approach for ensuring safety across a gate in a fence.
