I'm asuming you have 220V since this is a 220v Timer. See diagram at site:
http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/t104%20-%20english.ashx

Pay attention that the incoming circuit hots should be on 1 & 3 the same terminals that the clock motor leads connect to. Just to be sure it's a 220V clock motor, look at the back of the motor (it snaps out of the enclosure) and be sure motor says 220V.

Hello,

I suspect on teh wiring from the house the black&white will be the hot wires and the bare will be ground/neutral

use a volt meter before connecting tonew cooktop and check for;
black/bare to have 120volts
white/bare to have 120volts

if that is what you find...connect new cooktop as such;

black to black
red to (house) white

Utilitec 7-day timer will only replace single-pole switch.
Single pole switch has two brass screws and a ground screw.

Links below show wiring for both Utilitec 7-day timers
http://waterheatertimer.org/Program-wire-Utilitec-0192773.html
http://waterheatertimer.org/Program-wire-Utilitec-0141224.html
If this is not your timer, then add a comment and specifically state which timer you have and which wires came off which screw on old switch.

The best way to start is to identify exactly which wires came off old switch.
How to wire
1) Timer-green-wire connects to bare ground wire.
2) Switch has 2 insulated wires. Take switch wires and connect them to timer-black-wire and timer-red-wire. Choose either one for now.
3) In back of electric box are white wires twisted together and covered with wire nut. Connect timer-white to these wires.
4) If electric box does not have white wires described above, then connect timer-white to bare ground, along with timer-green wire.
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.

I have the unit wired and it does not wotk.I have black to black,red to red green to ground and white to white,any thoughts? Thank you


Electrician test wiring before connecting anything.
First of all, you don't mention what type of switch was replaced.

1) Leviton 6230 countdown timer is made to replace single-pole light switch only.
Single pole is where 1 switch controls the Load (light fan motor)

Your wiring sounds like 3-way switch.
3-way is where 2 switches control same Load.
For example a hallway usually has 3-way switches.

To confirm. If old switch has 1 dark screw, 2 brass screws, and 1 green screw, then that is 3-way switch. Use Leviton LTB15, LTB30, LTB60, LTB02, LTB12 countdown timer for 3-way.

http://www.smarthome.com/4255/Leviton-LTB60-1LZ-4-Button-10-20-30-60-Minute-Countdown-Timer-Switch/p.aspx


2) If old switch has 2 brass screws and 1 green screw then that is single-pole switch.

3) If you are replacing single-pole switch, here are testing & wiring instructions for Leviton timer.
Remove device and separate wires for testing.
Use ordinary two wire tester.
Tape tester leads to wood sticks so hands are away from power.
Do not untwist wires that were twisted together before you started.
Turn on power.
Test each wire to bare ground wire.
Tester lights up on Hot wire. This wire will connect to timer black wire.
Now you know Hot wire.
Test Hot wire to each of the other wires, excluding bare ground wire.
Tester lights up on neutral. Timer white wire connects to Neutral wire.
If box does not contain Neutral wire, then timer white wire connects to bare ground.

Timer green wire connects to bare ground wire.
Timer red wire connects to wire going to Load.

GE 15086 programmable timer replaces single-pole switch only.
Single pole means 1 device turns Load on-off.
3-way is where 2 devices turn Load on-off, for example 2 switches located in hallway.

Your existing timer has white, black and blue wires.
Your new timer has white, black, red and green wires.
Green wire connects to bare ground wire in every occasion with every wiring device.

Electricians don't guess, they test the other wires.

Remove old timer.
Separate wires for testing.
Turn on power.
Tape ordinary tester leads to wood sticks to keep hands away from power.
Test each wire to bare ground wire.
Tester will light up on Hot wire. The Hot wire will connect to timer black wire.
Now test Hot wire to each other wire (except bare ground)
Tester will light up on Neutral wire. Neutral wire connects to timer white wire.

The remaining wire connects to timer red wire.
After connecting timer, push manual override button to check that Load turns on-off.

Manual override on 15086 is the door that covers buttons > use door as push button to check Load.
Next, program the timer.
Programming is straightforward and similar to other timers.
If you have a problem, add a comment.

I've tested these timers.
Here's what to do:
1) Connect green to bare copper
2) Switch has 2 wires. For now, connect these two wires to timer-black and timer-red. Choose either one.
3) In back of wall box are white neutral wires twisted together and covered with wire nut. Timer-white wire connects to these white neutral wires. This action gives power to time clock.
4) If wall box does not have white neutrals described above, then connect timer-white to bare ground wire. Bare ground connects to neutral busbar in breaker box.
5) Turn on power and click manual override button or switch. If lights turn on, timer is wired correctly. If lights do not turn on, then reverse timer-red and timer-black wires.

New switch GE model 15265 ... to light up 2 lightbulbs outside. Old switch all cables are black. Those who light up the tester are the hot=Red/black?? Those which do not light up are white?? Green I know...


Manual for GE 15265
http://waterheatertimer.org/pdf/GE-15265-manual.pdf
15A timer works fine on two bulbs, up to 1440 total watts.

If old switch has 2 screws plus green ground screw, then timer is right.
If old switch has 3 screws plus green ground screw, 15265 doesn't replace 3-way switch.

Timer-green wire connects to bare ground wire

Old switch has 2 screws with wires on each.
One wire is Hot-from breaker and this connects to timer-black wire.
One wire Goes-to-lights and this connects to timer-red wire.
If you get these two wires reversed, timer will not work, so reverse them.
It will not blow circuit if the timer-red and timer-black wires are reversed.

Timer-White wire is the confusing wire for everybody:
Timer-white wire runs clock motor located inside timer.
In back of electric box are neutral white wires that are twisted together and covered with wire nut.
Connect timer-white to these neutral wires.
If box does not have neutral white wires, connect timer-white to bare ground wire.

You posted under ST01C timer which has 3 wires: black blue and red (no white wire)
Your description seems to say your timer has 3 wires: black white and red

These are two different timers
I'm going to give you two different instructions that are dead-accurate for both types of timers above:

1) Instructions for ST01C and EJ500 Intermatic timers with black blue and red
Lets do the black and white with electricity:
The black Hot wire connects to Timer-black-wire
The white Neutral wire connects to white wire going to Load (to lights)

Now the black and white to the Load (lights)
The black to Load (to light) connects to Timer-blue-wire
The white wires are connected together with wire nut

The red wire is capped off, and used only if you have 3-way switching.
Green connects to bare ground

2) Instructions for all in-wall timers with black, red and white wires (except Aube series timers)
Lets do the black and white from electricity
The black Hot wire connects to Timer-black-wire
The white Neutral connects to Timer-white-wire and to white wire going to Load

Now the black and white to the Load
The black wire to Load connects to Timer-red-wire
all three white wires are connected and covered with wire nut
Green connects to bare ground

DO NOT CONNECT RED TO WHITE with any model in-wall timer and then turn on power or it can blow out the timer >>> I just did that while experimenting with the Utilitec 0192773.
Red wire goes to Load on all timers, except with Intermatic ST01C and EJ500

Did you get instructions with the switch? Does it say what is line and what is load? You can hook the green and the white to the green, it won't hurt, but I think one of the colored wires is in and one is out, you have to find out which one is hot. Got a tester? The new timer is polarized for modern electricity, which hasn't gone into effect yet, it is coming. Your house wouldn't have it. If it does, you will know by the fuse box being separated by ground and neutral, the old ones were wired together. If it is, the new switch will only work with the white wire to neutral and the green to ground. Now that you are totally confused. try wiring it up with the green to ground, red and black to to the 2 blacks. See what happens. Hope this helps.

Utilitech Wall Timer #0192773 does not switch landscape lights on? Replaced Intermatic that had 3 wires. Black to Black, blue to black and red was capped. Utilitech came with 4 wires - black, white,...


Old timer: Intermatic EJ500 & ST01C timers have a battery. Battery operates the clock motor. Red wire is for 3-way circuit [a hallway with 2 switches is a 3-way circuit].

Utilitec timer, clock runs on 120Volt circuit instead of battery. So clock has to have power.

How to connect wires:
Black timer wire connects to hot wire from breaker box.
Red (or blue) timer wire goes to landscape lights.
White timer wire connects to white neutral wire [or if no neutral is available, connect to bare ground wire].
Green timer wire goes to bare ground wire.

How to find black hot wire and white neutral wire inside box
: Disconnect and separate wires so you can test. Use ordinary tester. Power is on. There is only 1 black hot wire inside each electrical box. Test each black wire to bare ground until tester light comes on > that identifies the black hot wire. Next, test black hot wire to white wires until tester light comes on > that is the neutral wire. Exception: This test does not necessarily work with 3-way switches since they reverse each time switch is thrown.
