Who sizes Elevator Fused Disconnect Switch?

[designer82]

Working on a basic, single elevator project.
Vendor is telling me they don't size the Fused Disconnect switch protecting the elevator controller/elevator due to liability?

Would you agree with the above and it should be sized by the engineer?
I would think the vendor should size it.

The vendor probably does not have a PE licensed in Mass, and the law in most states would classify that as engineering work.
Typically the only exemption from PE law is being a licensed electrical contractor doing a design/build.
