I do not actually know. My point was simply in response to the question of 'does UL mean anything anymore'. Whether a product was properly categorized and safety risk properly assessed - I do not know. So your point is that the UL stamp on the motor may be good enough. Could be true. Not sure. (Does UL cover 'only' electrical connections, or does it include other aspects of safety like exposed vanes, imbalance, proper install, packaging failure, potential for misuse, manuals, etc?) And if you are buying 'components' does that shift risk to the user doing the assembly?
In theory this assessment was made during the development process prior to release for sale, and deemed good enough for that particular manufacturers appetite for risk.
Glenn is correct.
And by no means was I meaning to fan flames or come across as all knowing... could not be further from the truth so my apologies. (Just have seen first hand a handful of lawsuits due to product failures, which in some cases turned out to not be due to the product at all but instead customer neglect... and at least one case, even with UL stamp, was deemed inadequate design controls and the company was held liable). Also have experienced several instances of aggressive customer behavior trying to get a settlement that was undeserved (in the consumer world some bozo somewhere is going to sue, even if unfounded, just because they think they might get a big $$).
