Bought 2 LED lit mirrors with defogger May of 2021. Installation documentation is incomplete (at best). Site states they are Code compliant for the USA. The 120V internal power supply device has an internal UR (Underwiters Lab mark for certified products that are intended to be used inside of other devices). The tail supplied is 2-wire. No grounding wire. [The internal AC/DC power supply is a Jinbo JLV-12030KA-U] The NEC has required since 1971 -and now mandated for use as of 2020, connection to a GFCI. The Grounding is material to the GFCI operation. Regardless if a combination GFCI/AFI or AFI, or GFCI sensor to work. 2-wire connected devices requires labeling of an uncertified ground. The Jinbo has a ground wire that has been cut & capped. Ungrounded condition would take a separate UL card file. Which is not provided or referenced. No wiring diagram provded. Wholly unresponsive customer service or even an FAQ. No direction provided for "compliant" installation.
