How do I add a wall-mounted master control if there is no wallbox?
• Replace a set of “3-Way” switches with a dimmer and master control. (Note: Not all 3-way wiring schemes will allow this replacement.) • Rough out a new wallbox over an existing box, mounting the master control at eye level (60 inches) and running hot and neutral from the existing box. • Add a gang to an existing wallbox. • Rough out a new wallbox over an existing receptacle, mount the master control at eye level and run hot and neutral from the existing receptacle.
