Single pole timer
(With or without neutral wire available inside box)
Applies to most ordinary in-wall timers
How to replace ordinary wall switch with single pole timer
Your wall switch has 2 wires, plus green ground screw for bare-copper ground wire.
Timer has 3 wires, plus green ground wire.

Extra wire on timer is used to run clock inside timer.
Typical in-wall timer clock consumes .8 Kwh per year

Manual says:
Timer-Black-wire to Hot;
Timer-Red-wire to Load (lights)
Timer-White-wire to Neutral.
Timer-Green to ground.
Heres what to do
1) Timer-green-wire connects to bare ground wire.
2) Switch has 2 wires.
Take switch wires and connect them to timer-black-wire and timer-red-wire.
Choose either one for now.
Variations: (Leviton timers have blue wire instead of red) (and Some 3-way timers have both red and blue... use blue and cap red)
3) In back of electric box are white wires twisted together and covered with wire connector. Connect timer-white to these wires.
4) If electric box does not have white wires described above, then connect timer-white to bare ground. Timer will work until you have time to run additional White neutral wire from nearby outlet.
5) Turn on electricity, and push ON-OFF button. If lights come on, timer is wired correctly. If lights do not come on, then reverse timer-red and timer-black wires.
If lights blink after installing timer, then white wire is connected to red wire.

1) Strip stranded wire longer.
2) Wrap stranded around the solid wire
3) Twist wire connector over both wires
4) Twist wire nut very tight
5) Pull stranded wire and make sure it will not come loose
