How to wire air compressor motor to 220v

OK, your new switch will require the use of a neutral wire. So you will have to do what is called a pigtail. You will have to twist another white wire in with your other white wires to attach your neutrals to your switch. Note: white wires are called neutral not common. Hook the wires that were originally hooked up to your LINE to your HOT (Black) on your new timer, and the what was originally LOAD up to the new timer LOAD. SO as far as wiring all that will change is your white wires that need to attach to your timer NEUTRAL.

Find the Hot wire:
Your switch has 2 wires. One of these wires is Hot, and one goes to load. Disconnect wires from switch. Turn on power. Do not stand on wet surface. Test each wire to bare copper wire. When tester lights up, that is Hot wire. The other wire goes to load.

Connect wires:
Hot wire goes to Black timer wire
Wire to load goes to Red timer wire
White wire connects to white wires that are twisted together
Bare copper wire connects to Green wire from timer

How to connect white wire to white wires that are twisted together.
a) Strip white timer wire so you have 1-1/2 " of bare wire. Stranded wire will wrap around other wires easily.
b) Remove wire nut. DO NOT UNTWIST wires.
c) Hold all whites together so bare copper lines up. Wrap stranded copper around the twisted wire.
d) Replace wire nut, or use larger wire nut. Twist real tight. Do not use tape. You can solder the connection.
e) When done, pull on white time wire to make sure it is held tight. Push whites back into box.

Review:
Black goes to Hot wire from breaker box
Red wire goes to Load (light, fan, motor)
White wire goes to Neutral
Green to bare copper ground wire

Orientation:
Your original switch had 2 wires plus bare ground.
One of these wires is Hot, the other goes to Load.
You said original wires are Red and Black

How do you find Hot wire?
-Your original switch had 2 wires.
-Remove timer from box.
-Pull original 2 wires out where you can test them
-Turn on power
-Use regular tester
-Tape tester leads to wood sticks so your hands stay away from voltage
-Power is on
-Test each original wire to bare ground wire
-When tester lights up, that is Hot wire ... this wire connects to Black wire on timer
- The other wire goes to Load so it connects to Red wire on timer

How to test for Neutral wire
Test Hot wire to your white wires - No need to untwist them.
When tester lights up, that is Neutral
White wire from timer connects to Neutral.
Green goes to ground wire.

How to reset timer
I'm not sure which timer you have. Probably GE 15086. Reset is small round button below HOUR button. Use paper clip and push-in reset until timer flashes 12 o'clock.

SOURCE: I the manual wiring doesn't match what I have in

I test these timers.
GE 15071 timer has internal clock that runs on electricity. That's why timer has extra wire.
Intermatic, GE, Tork, Leviton, Sylvania, Woods, Utilitec etc in-wall timers each wire the same way.
The only tiny difference is GE doesn't have green ground wire.

Here's what to do:
1) Old switch has two screws (excluding green ground screw)
One screw on old switch has 2 black wires >> these are hot wires > timer black wire connects to these hot wires. This will power the timer.
2) The other switch wire connects to timer red wire. This will send timer signal to lights.

3) Timer white wire is for the timer clock.
Timer white wire connects to other white wires that are twisted together and covered with wire nut >>> these are neutral wires, and now timer clock will operate
4) For EZ connection to other white wires, strip back another inch on timer white wire so stranded wire can wrap like a candy cane around solid copper wires. Then twist wire nut on very tight.

5) When wiring is complete, push door on timer for manual override. Lights should turn ON-OFF. If lights do not turn on, reverse timer red and timer black wires. Make sure outdoor bulbs are working.

Thank you for clear description of wiring, switches, and for including timer model number.

1) Open following link for ez programming and wiring for Utilitec.

2) Your single-pole switch has 2 wires.
0192773 replaces single-pole switch only.
Black wire that connects each of the switches is Hot wire: connect this wire to timer Black wire.
Other black wire that connects to switch goes to load: connect this wire to timer red wire.
Timer white wire connects to white wires that are covered with wire nut.
Timer green connects to bare ground wire.
