What is the primary purpose of a bonding wire between metallic containers?

Bonding wires keep metal containers at the same electrical potential. As flammable liquids are transferred or poured, static charges can build up on each container. If there’s a potential difference between containers, a spark can jump when they’re connected or during handling, creating an ignition risk. The bonding wire provides a conductive path so charges flow and equalize, eliminating the voltage difference and the chance of a spark. This isn’t about making everything more conductive or preventing corrosion, and it doesn’t serve as a leak detector.
