I am trying to upgrade a switch that controls two wall outlets in a 2-gang switch box with a Kasa smart switch. The wall outlets controlled by the switch are split switched outlets.
Here's a diagram of my existing configuration (in the US, the house was built in 2013):
I'd like to understand the function of the cables in this configuration and use that to install my new smart switch.
So far, the one thing I know for sure is that the (bare) copper cable is ground :). As per my research, I believe these statements are true:
- The white wires are neutral (the 2011 NEC mandates that a neutral wire be present in switch boxes).
- The top 3-wire cable connects the switch box to the fan.
- The bottom 3-wire cable connects the switch box to the wall outlets; I have split switched outlets with a switch loop, where the source is located at (one of?) the outlets.
- The hot wire coming from the switch loop is spliced and goes to both switches.
Is that accurate? What tests can I run with a multimeter to confirm this?
I'd be happy to report back with multimeter test results (once I know what tests to perform) if that helps with the identification. Thanks a bunch!
