Is an inhibitor required to be applied on all aluminum connections?

An inhibitor is indeed required for all aluminum connections to prevent corrosion and ensure electrical continuity. Aluminum is susceptible to oxidation, which can lead to the formation of aluminum oxide on the surface of the connections. This oxide layer can act as an insulator, increasing the resistance at the connection point and potentially leading to overheating or failure.

The application of an inhibitor helps to mitigate these issues by providing a protective barrier against moisture and contaminants that can cause corrosion. This is especially critical because once aluminum begins to corrode, it can be challenging to maintain a reliable electrical connection.

While it might be tempting to think that inhibitors would only be necessary in specific situations, such as wet conditions or underground connections, the reality is that any aluminum connection stands to benefit from the protective qualities of an inhibitor regardless of the environment. Therefore, applying an inhibitor on all aluminum connections is a best practice that ensures reliability and longevity in electrical systems.
