Codes
Install in accordance with all national and local 
electrical codes.
Grounding
When no “grounding means” exist in wallbox, the 
National Electrical Code (NEC®) allows a control to 
be installed as a replacement if 1) a nonmetallic, 
noncombustible faceplate is used with nonmetallic 
attachment screws or 2) the circuit is protected by a 
ground fault circuit interrupter (GFCI). When installing 
a control according to these methods, cap or remove 
green wire before screwing control into wallbox.

Some lights have one wall switch, while others 
have two or more wall switches (such as stair 
lights, which have a switch at both the top 
and bottom of the stairs). We’ve included 
instructions for lights with one wall switch 
(called a single pole). If your light has more than 
one switch (called a 3-way), please visit 
www.casetawireless.com/3way for 
complete installation instructions and how-to 
videos.

  The maximum lamp wattage is determined by the efficiency of 
the transformer, with 70%–85% as typical. For actual transformer 
efficiency, contact either the fixture or transformer manufacturer. 
The total VA rating of the transformer(s) shall not exceed the VA 
rating of the in-wall switch.
