Can bonding conductors be connected to either aluminum or copper busbars?

The correct answer reflects that bonding conductors can indeed be connected to both aluminum and copper busbars, but there are specific requirements that must be met to ensure safety and compliance with electrical codes. This is important because both types of busbars have different properties and conductivities that could affect their performance in a bonding system.

For instance, when connecting a bonding conductor to aluminum busbars, it's necessary to use appropriate connectors and apply anti-oxidizing compounds to prevent corrosion and maintain a good electrical connection. Similarly, different expansion rates between aluminum and copper may necessitate special considerations when installing connections together to prevent issues due to temperature variations.

Recognizing these requirements helps ensure that electrical systems maintain proper functionality and safety standards. Thus, understanding the nuances of connecting different metals in electrical systems is crucial for professionals working in the field.
