When is it acceptable to use uninsulated bonding jumpers?

Uninsulated bonding jumpers should never be used in any situation because they pose significant safety risks and violate electrical codes. Bonding jumpers are essential for establishing a safe, low-resistance path for electrical current in case of a fault, and they must be properly insulated to prevent accidental contact with live circuits. The use of uninsulated bonding jumpers can lead to electrical shock hazards and increase the risk of equipment damage.

In scenarios such as residential use, relying on uninsulated jumpers would compromise the safety measures put in place to protect both properties and individuals. Similarly, while the use of copper wire is common in electrical work, the presence of uninsulated components in any wiring system is unacceptable. Finally, temporary fixes should adhere to the same stringent safety standards as permanent installations; therefore, using uninsulated bonding jumpers as a temporary solution is inappropriate. Proper insulation ensures that all components of the electrical system function safely and effectively.
