Just getting started with all the fun things, and first light I attempted to replace has no existing ground (Metal box, simple dimmer switch). This is a large condo complex so want to avoid any major reconstruction projects
The caseta quick start guide states the following:
GroundingWhen no “grounding means” exist in wallbox, theNational Electrical Code (NEC®) allows a control tobe installed as a replacement if
1) a nonmetallic,noncombustible faceplate is used with nonmetallicattachment screws or
2) the circuit is protected by aground fault circuit interrupter (GFCI). When installinga control according to these methods, cap or removegreen wire before screwing control into wallbox.
As this is an entry switch, there are no outlets nearby to add GFCI. As such, can anyone confirm that the Claro screwless faceplates meet the requirements of #1?
There are still metal screws attaching the switch to the wall, but these would be covered up by the switch plate.
