Should antioxidant paste be used on all aluminum conductors?

Using antioxidant paste on aluminum conductors is not a universally required practice. The correct approach depends on the specific application and environment. In many cases, it is advisable to use antioxidant paste to prevent oxidation and enhance conductivity at connections, especially where aluminum conductors are involved, as these conductors are more prone to oxidation than copper.

However, using antioxidant paste on all aluminum conductors is not necessary. There are scenarios, such as in dry or controlled environments and certain types of installations, where the application of antioxidant paste may be excessive or irrelevant. For example, in secure indoor settings where moisture and environmental factors are minimal, aluminum conductors may not require the added protection afforded by the paste.

This understanding emphasizes the necessity of assessing each situation individually rather than applying a one-size-fits-all approach to the use of antioxidant paste.
