Replacing old switches with kasa 220. Replaced almost 20 of them without any issues. Finally opened this switch box that controls the pool light and pool waterfall and I am stumped. Please help.
Here is a diagram (Actual PICS at the bottom of the post, they are too cluttered) of all the stuff in the box with the voltage readings against the ground wire:
My main points of confusion are :
a) The three capped wires are all by themselves, not connected.
b) Which is the neutral wire than I can use for the two smart switches?
c) Why is there a low (approx 20 V) voltage in the white wire in the lower left sheath ?
Thanks.
