During installations, what is essential to prevent corrosion in bonding connections?

To prevent corrosion in bonding connections, essential measures focus on maintaining the integrity of the connections against environmental factors. Environmental protection involves the application of barriers or coatings that shield connections from moisture, chemicals, and pollutants. These external factors can lead to corrosion, which undermines the reliability and safety of electrical systems.

In practical applications, ensuring that bonding connections are protected from conditions such as water exposure or corrosive chemicals is vital. This can be achieved through the use of protective coatings, sealants, or by placing connections in less exposed locations, thus mitigating the risk of corrosion over time.

While other options may play roles in ensuring effective bonding connections, such as proper torqueing to ensure a tight join or the use of sealants in some contexts, the primary focus here specifically highlights the importance of environmental protections against corrosion, making it the most relevant choice for the question asked.
