What best practices should be followed when connecting grounding to structural steel?

Both using corrosion-resistant connections and ensuring that no insulation barriers are present are essential practices when connecting grounding to structural steel.

Using corrosion-resistant connections is crucial to maintaining the integrity and effectiveness of the grounding system over time. Corrosion can lead to resistance in the grounding path, which diminishes its effectiveness in providing safety against electrical faults. Materials such as stainless steel, copper, or other alloys that resist corrosion should be used to ensure a reliable connection.

Additionally, ensuring that there are no insulation barriers is equally important. Insulation can prevent a proper electrical connection between the grounding system and the structural steel, ultimately compromising the ground's ability to dissipate fault currents. This could result in hazardous conditions where the electrical system fails to properly route excess electricity to the ground, potentially leading to equipment damage or electric shock.

Thus, recognizing the importance of these two aspects in grounding practices enhances the safety and efficiency of electrical installations, making the combined approach the correct choice.
