Hi all,

We use a popular anodized aluminum extrusion product for some of our custom equipment enclosures.

Please forgive the commercial link, but something like these:

I'm concerned about proper earthing of of all of these anodized aluminum bits, specifically with the above mentioned manufacturer.

Does anyone have any experience with this issue? They do sell an "anodization breaker" meant to electrically connect two adjacent pieces (Part# 12300). However no specs are given.

This type of AL extrusion system is very common in industry/factory floors. Any insight would be welcome.

Regards,

Chris

We use a washer between aluminum solar panels and the aluminum rails. They pierce the anodized coating. Might work, it can be used with a ground lug too.

I suppose you use that with grease. As dissimilar metals and the elements will quickly oxidize, compromising the connection.

I wonder what the automation guys and factories do with this aluminum extrusion stuff?

How do they ground entire assemblies?

For some reason, is this not a concern for these 8020 guys?

No grease, the washer system seals it self. I think it called a WEEB washer.
