Issue installing 3-way switch HS210 kit
I wanted to install an HS210 3-way switch but the light bulb started repeatedly turning on and off. I have two sets of wires coming into the first switch box. A three-wire and a two-wire.
I removed all the connections from the switch box and noticed out of 5 wires only the white one coming out of the two-wire set is hot. I think it should be the black one. Right? Is it possible that the previous electrician mistakenly used the white as hot?
what should I do in this case?
