How to install timer
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
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 instad 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.
