I recently had a renovation complete with only the rough in work done for electrical. Due to the pandemic, its hard to get people to come by to finish the work. I am trying to install a single pole light switch for my laundry room, but i am confused by the layout of the wiring to the box. It seems there are four wires coming into the box – and i cant tell which to use to wire the switch.
Any help would be really appreciated, or an explanation. Thank you!
