Is it safe to cap and abandon a neutral wire for a standard switch?
When replacing a smart switch with a conventional switch, you can safely cap the unused neutral wire and leave it hanging in the electrical box while connecting only the hot, load, and ground. Standard conventional switches do not require a neutral connection to operate safely, provided the bare copper or green ground wire remains properly connected.
