Basement wiring


The electrician I hired to wire my basement went out of business so I can't get an answer from him. I finished an office downstairs and went into the light switch box to hook up a switch for lights and found 3 sets of Romex going into the box. I am confused. I was expecting 2. I am figuring the 3rd might be the smoke detector that is in the room? I need lights!! I doubt all 3 get hooked up to the single switch but what do I know. Please help if you can. Thanks.

You might have a power in, a power out and a cable running to the lights. Are any splices made in the switch box?

How many cables and what kind are in the box for the smoke alarm?

Thanks for the quick response. I can't see what comes from where any longer since it is behind drywall. The 3 whites are wire nutted together as are the grounds.

If you are comfortable you could install a single pole switch temporarily to see if you can get the light to work. This may take a couple of tries. The black that does not get used would still need to be figured out. A toner to follow that black might help.

Is there 1 black wire wrapped around the other 2, or vice-cersa?
