Hi,
The subject more or less says it all, my question is: "Is using a UL or
CSA approved wall wart considered a safe, legal, and relatively
liability free way to create devices for retail to end users?"
The background to this, is that I've been asked to research the UL
requirements for some friends who are looking to import low power
electrical devices from overseas. The devices are not currently
certified or tested to any North American standard. They are low
power; however, so I am wondering if it is a good idea to switch the
power supplies to UL listed wall warts.
I've done a quick survey of gear around the house, and with the
exception of my laptop, I have not found any wallwart powered devices
that have a UL or other stamp directly on the device -- they all seem
to rely on the safety (and implied reduction in liability) offered via
external power supplies.
Thanks in advance for the insights!
Regards!
Leonard
