They add smart control to the existing electrical installation without replacing the visible switches and loads.
Installation must be completed by a qualified electrician. Before ordering, verify the neutral conductor, box depth, load type, inrush current, total power and existing protection devices. Current and power ratings do not imply equal suitability for every load type; motors, transformers and LED drivers require separate confirmation.
