I want to install an in-wall lighting timer for my front outdoor lights, replacing an existing light switch. I turned off the breaker to the switch I wish to replace and I've determined which black wire is the line (blue tape in image).
The timer switch installation calls for using a single neutral wire, but I have two separate neutral wires on the existing light switch. As well, no ground wire is installed on the current switch; I do however see some ground wires twisted together in the same box behind the other switch.
To install the timer switch, do I wire-nut both neutral wires together with a pigtail to the timer switch neutral screw and pigtail a ground to the current ground-wire group?
Thanks in advance!
