On a slightly related topic....a machine tool dealer was telling me
he is losing sales of certain CNC machines to larger companies.
These companies no longer will buy equipment unless it has UL
approval. It's an insurance issue of some kind, not sure if it's
labor & industries or the private insurance provider who is creating
the requirement.
In cases where the machine manufacturer has not sought UL approval
the potential purchaser has the option of hiring a professional
engineeer to inspect the machine and certify the wiring is properly
done.
The Haas and Fadal "starter" mini-mills are two machines the dealer
mentioned as not having UL approval. He felt sales of these will
suffer without the UL rating.
