I just bought a house - it was built in 1966. I want to replace some
light switches with timer switches that can control compact
I bought two different timers - a Grasslin KM2 and an Aube 1103. Both
timers have three wires and require a common wire.
I tried to replace the first switch. It's one of three switches in a
3 gang box. Each switch is a regular one way switch.
Here's my question. What's a common wire and how do I figure out
which one it is.
There's a jumble of three different wires in the box - white, black
The switch I want to replace has two black wires to it. The switch
next to it has a black a red wite to it. One of those black wires is
connected to one of the black wires on the switch I want to replace.
Can I assume that this black wire is the LINE (these 2 switches get
power from the same circuit - the 3rd switch is on a different
circuit)? The other wires (the red on the other switch and the other
black wire on the switch I'm replacing) should be the load wires,
So my questions are:
1. What is a common wire and how to identify it?
2. The LINE wire is the hot wire, right?
3. The load wire goes from the switch to the light, completing the
