If I have something that drives a motor, destined to be installed in a comsumer enviroment, must it be UL certified? This will be behind a panel, no exposed wiring, etc. I heard once that UL certification meant...it was tested not to explode or burn up due to normal idiot operation, but never meant as a total safety certification.
