Hello.....my name is ***** ***** I will be happy to assist you with your electrical question. My goal is to exceed your expectations on Just Answer!
1) When a wire is looped around a switch terminal screw, that is typically for the hot circuit feed or the LINE side of the switch. Looping wires on switch screw terminals is old school and is not recommended. Should have been a pigtail splice originally. If you have an AC voltmeter available, you can confirm that the looped wire is the constant hot circuit feed into the switch.
2) You can also confirm the wire colors by performing a visual inspection of the load that you are trying to time.....ie.... if a light fixture, take a look at the 2 conductors that splice to the light. If one of them is yellow, that is the LOAD side or the "switched loop" conductor that was leaving the light switch and extending out to the LOAD.
3) Yes, green is always used as the equipment grounding conductor.
Hope this helps………If you have any additional questions, let me know and I’ll be glad to answer them for you.
