Should inhibitor paste be applied to aluminum wire in the service entrance panel?

Inhibitor paste is typically used on aluminum wire connections to prevent oxidation and enhance conductivity. However, its application must be approached with caution. The presence of inhibitor paste can help reduce the risk of corrosion that can occur if aluminum is not properly maintained.

That said, the application of inhibitor paste is not universally required in all situations. In some contexts, using inhibitor paste may lead to unintended consequences, such as promoting corrosion if applied improperly. Therefore, the specific requirements of local electrical codes or the manufacturer's recommendations often guide its use.

Ultimately, correctly applying inhibitor paste according to best practices allows for optimal performance and longevity of aluminum wiring connections, making it essential to consider both the material properties and local code requirements when deciding to apply it. This means that while it may seem beneficial to always use inhibitor paste, it's important to evaluate whether it is the right choice for each specific installation.
