A small open-frame line powered power supply (Cincom CFM05S033) doesn't
have a ground connection. It will power a tiny device which only has
+3.3V/0V DC connections. This will be used in a 6x6x4 plastic enclosure so
there is no chassis ground. An electrician will be wiring it in.
Is this inherently unsafe? Do I need to find another supply with a ground?
Perhaps someone can suggest how to safely wire and enclose a small 3.3V
device with 120VAC power supply for use outdoors.

be ungrounded and all the energized parts will be enclosed by the
maker so you won't need to worry. By the way, please don't pay
attention to phil allison. He is probably in need of professional help
but instead spends his time trying to rile up anybody he can online.
Just like when CB radios were a big craze and all sorts of shy whackos
would get their hands on a radio and broadcast all sorts of stuff
pretending to be something or someone they were not.
