What purpose do bonding jumpers serve?

Bonding jumpers are crucial components in electrical systems primarily used to ensure electrical continuity between connected parts. This means they create a low-resistance path that allows for the equal distribution of electrical potential across different conductive elements. This continuity is essential for preventing differences in voltage that could lead to dangerous electric shock hazards or equipment damage.

By connecting various conductive parts, bonding jumpers help to maintain the same electrical potential across these connections, reducing the risk of electrical arcing or other issues that could arise from potential differences. They effectively mitigate the risk of stray voltage and enhance safety by ensuring that all bonded components are at the same voltage level, which is especially important in systems with multiple metallic parts.

While bonding jumpers play a role in ensuring safe and effective operation of electrical systems, they do not connect non-electrical piping systems, ground isolated devices specifically, or regulate voltage levels. Their primary function is to support safety and reliability by maintaining electrical continuity.
