Typically stainless steelWhat is the enclosure made of where these hubs will be connected?
Just be careful with the spec.So this has a locknut on it but no bushing. Is a sperate bushing required? I assume no beccasue it has an insulated throat?

Nema 4x..why?What is the enclosure made of where these hubs will be connected?
You're correct that is spec most of the time. I believe it's a locknut with a screw on itJust be careful with the spec.
Often times the specs call for these hubs to be grounding type
It comes with a bonding locknut. You could also purchase the grounding locknuts separately.
If it's stainless steel there's going to be a galvanic corrosion issue with the hub. We started switching to stainless steel hubs to prevent the issue.Nema 4x..why?
I think those would probably cost less too.If it's stainless steel there's going to be a galvanic corrosion issue with the hub. We started switching to stainless steel hubs to prevent the issue.
However, if the design and specifications called for this, then that would become a design problem.
The issue would become protecting the threads at the hub. The SS hub will not have the protected sleeve that the one you showed does.I think those would probably cost less too.
