Measure the voltage across the two hot leads. if it is at least 208 volts that is considered 240 volts. If it is not at least 208 then you are not connected to both phases at the breaker/fuse box assuming you have two phases in the box. With the cover off of the breaker panel, look near the top for two LARGE GUAGE cables. Eack will be connected to a seperate POWER BUSS. If that is what you find then when your wires are connected one each to a two pole Breaker you will have designated 240V power.

Testimonial: "granitledge and gbob59 hit it right on the head. I was using a thin double breaker and did not hit the second phase. Went with a full size breaker and it worked great. Thanks so much."

Sounds like a bad connection at the Main breaker box and the 220vac 30 amp breaker or more.

Can a tork timer 1101 be used to control a 240 volt pool pump motor by controlling only 1 lead of the motor thus having the other lead hot all the time?


Yes: 240 volt can be controlled by turning off 1 hot leg of 240V circuit.
But the tork 101 clock motor still requires 120Volts (unless you buy a tork 240volt 201 clock motor to replace the 120volt 101)

Copy following links for handy resource and wiring diagram:
http://waterheatertimer.org/Tork-timers-and-manuals.html#1101

http://waterheatertimer.org/images/Tork-1101-wired-to-control-240.jpg

In the wiring diagram above, it shows white neutral wire running to Tork 1101 timer terminal 2. Bring this white neutral wire from any nearby 120volt outlet.
In event that you do not have this white neutral wire, you can connect ground wire to terminal 2 and that will give 120volts to the 101 clock motor.
Completing circuit to clock motor using ground wire is violation of national electric code for many reasons, however the tiny clock motor only draws 3 watts, and you will remember to bring a white neutral wire to this timer at later date so you can sleep better at night.

How to wire a cooper Quadra Mark MH 277 Volt light


Quadra mark is commercial metal halide light
It appears the 208-240 480V model is different from 120, 277 or 347V model.
You cannot connect 277Volt light to 240Volt
These are two different things.
Commercial 277V has 1 hot leg and a neutral (very similar to residential 120V which also has 1 hot leg and neutral)
http://waterheatertimer.org/images/How-to-wire-outlets-14.jpg
While residential 240V has 2 hot legs
http://waterheatertimer.org/See-inside-main-breaker-box.html

Check rating label on light and see if it shows 120V in addition to 277V
If rating plate shows 120V, then it should work.

Residential 240Volt has 2 hot legs, each Hot leg measures 120V to ground
So you can use one Hot leg from the 240Volt breaker, and use ground wire to make 120Volt circuit.
Using ground wire to complete circuit in this manner is completely out of code and not recommended by any professional electrician. But it will work.

You have 220Volts (same as 240V), then that circuit does not need a neutral.
All household single phase voltage requires two wires to complete the circuit.
With 120V, you have 1 hot wire and 1 neutral wire.
With 240, you have 2 hot wires, and these hot wires are called 'out of phase' since each comes from separate side of breaker box.
Notice that your 220V 10-2 wire goes back to a double breaker. This double breaker snaps over two different busbars. The breaker pulls 2 out of phase 120Volt lines, and when testing voltage across those two out of phase 120V wires, you get 240V potential.
The ground wire is redundant safety in both 120 or 240 Volt circuits, and is not necessary for either 120 or 240 to operate.

New intermatic T101 timer problem - timer is not


Manual override lever is good overall test of T101 120Volt timer.
T101 timer has 3 terminals: A 1 2

See wiring diagram on following link:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101

Electricians test, they don't guess.
So test your wire:
Separate all wires for testing.
Use ordinary 2 prong tester.
Tape wood sticks to tester leads to keep hands away from power.
Stand on dry boards. Do not hold or touch anything metal.
Turn power ON.
Test each wire to bare ground wire.
Tester lights up on Hot wire. 120V circuit has only 1 Hot wire. If you have 2 Hot wires, you might have 240Volt circuit and need T104 timer. If circuit has 1 Hot wire, then that Hot wire must connect to terminal 1.
If you have NO Hot wire, then check circuit breaker.
Hot wire is identified.
Now test Hot wire to all other wires, except bare ground wire.
Tester lights up on Neutral wire. Neutral wire must connect to terminal A.
If you have NO Neutral wire, then additional wiring is needed, or circuit needs further testing to see what type of wiring you are working with.
Bare ground wires connect to green ground screw.

Notice there are small white wires also connected to terminals A and 1. These small white wires power the 120V clock motor. With Hot on terminal 1 and Neutral on terminal A, the clock motor will run, and yellow dial will rotate.

If timer dial does not rotate after connecting Hot ans Neutral, then test voltage across Hot and Neutral to make sure it reads 120V.

Your circuit should have 2 wires remaining.
These wires go to 120Volt load (fan, light, motor)
Connect these two wires to terminals A and 2.
Try manual override.
If Load turns ON-OFF, then timer is wired correctly.
If Load does NOT turn ON-OFF, then reverse Load wires on terminals A and 2.

Add a comment any time.

How to wire a intermatic timer T104 240 v to a 120v?


T104 is 240volt timer.
Timer has terminals A 1 2 3 4
T-104 clock motor must receive 240Volts to operate.
Clock motor wires are white-colored and can be seen connected to terminals 1 and 3.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
http://waterheatertimer.org/images/Back-of-WH40-2b.jpg

There are two work-arounds for using T104 for 120V.

1) Diagram 1 showing how to change wiring:
http://waterheatertimer.org/images/T-104-control-120V-Load-500.jpg
Move 240V clock motor wires to terminal 1 and A.
Connect 240V Hot leads to terminals 1 and A. This will power the 240V clock motor
Hot wire going to 120V load connects to terminal 2. This wire will be turned on each time timer turns on, and 120Volts will power the 120V load.
To complete 120V circuit, neutral wire that comes from neutral busbar in breaker box connects to 120V load.

To control additional 120Volt circuit, run jumper wire from terminal 1 to terminal 3.
Connect Hot to second load to terminal 4.

2) Second method is to change T104 timer into T103 timer:
http://waterheatertimer.org/images/T-104-control-120V-Load-2-5.jpg
Replace T104 240V clock with identical 120V clock motor from Grainger
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK1?Pid=search
Neutral wires connect to terminal A.
Hot wire from Breaker connects to terminal 1
Hot going to Load connects to terminal 2

To control additional 120Volt circuit, run jumper wire from terminal 1 to terminal 3.
Connect Hot to second load to terminal 4.

How do you wire a intermatic t103


I'm looking at the T-103 sitting here in my office.
Terminals are labeled: A 1 2 3 4
I have about 10 different Intermatic timers on the shelves & each is a bit different

The T103 has a 120Volt (or 110V) clock motor
You need a white Neutral wire to operate the T103 clock

120V: Let's say your Load (light, fan, pump) is 120V
The white Neutral from breaker box connects to Terminal A
The 120V black Hot wire from breaker box connects to Terminal 1
The black wire going to Load (fan, light, motor) connects to terminal 2
The white wire going to Load connects to terminal A along with the Neutral
Ground wires connects to green ground screw
If your wires from breaker and wires to load are wired in reverse, the timer will turn ON the Load but the timer will not shut the circuit OFF.
To test which wire is Hot and Neutral, look at explanation at bottom of page.

240V: Let's say your Load is 240 Volts (or 220 Volts)
The clock motor is still 120V so you still need a white Neutral wire connected on Terminal A
Now you have 2 Hot wires coming from breaker box
Hot wire 1 from breaker box connects to Terminal 1
Hot wire 2 from breaker box connects to Terminal 3
Wire 1 going to Load connects to Terminal 2
Wire 2 going to Load connects to Terminal 4
Ground wires connects to green ground screw

What if you don't have a Neutral wire and you are wiring a 240V circuit?
240V circuits normally have 2 hots and a ground, but no neutral
Buy the T-104 timer
The T-104 has a 240V clock motor
Wiring for the T-104 is exactly the same as 240V wiring shown above for T103 EXCEPT there is no Neutral on Terminal A, and Terminal A is bare
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

How to test which wire is Hot
Test requires wires with live electricity >>> this is not advisable without precaution
Stand on dry boards, do not touch anything metal, wear dry clothes, do not hold screwdriver in mouth, wear gloves, tape tester leads to wood sticks so hands are away from power
Remove wires from terminals
Separate wires so they can be tested
Turn on power
Test each wire to bare ground wire
Tester lights up on Hot wire(s)
If circuit is 120V, then there is only one Hot wire
If circuit is 240V, then 2 wires will test hot to ground >> these wires will be Hots 1 & 2
Test assumes circuit breaker is functioning normally.

How do you test for neutral?
If you have 120V line with only 1 hot wire, then one of the white wires will be Neutral?
Test Hot wire to each white wire
Tester lights up on neutral

WHAT SIZE OF WIRE IS NEEDED TO CNNECT AN OVEN AND HOW AMPS BREAKER


3 # 6 wires for the power phase wires and neutral, you can get by with a # 8 on the neutral, but that wire carries all the current im-balance so why scrimp, if you need a safety ground wire i.e. 4 wire plug required in some areas you can use a # 8 wire for this, the # 6 wire will carry 60 AMPS/the # 8 wire will carry 40 amps, most stoves use max 40 amps

Elec dryer, no heat case


check your center NEUTRAL connection to the element,sounds like your losing it somewhere,certain units rely on the neutral to operate the element on certain cycles to dry, the neutral carries the imbalance current load and the wire gets hot and will get brittle and break

I need to know which wires go into which transformer lead there is a red wire and grey connected together then orange and black together then yellow and black together then black comming from air...


first find out your voltage..240 or 208...then it is 2(two) wires high voltage and ground. Both high voltage should go to transformer one on common lead another to 240 or 208 lead( if you have up to 218 use 208 lead...), transformer ground it self so don't worry about ground. other side of trasformer got 2 wires it will be your 24 volts..normaly it is blue and red( ruud-rheam-goodman red and grey, carrier red and brown)...if you need to know how to "hook it up" low voltage let me kow..totalcarefl@yahoo.com
