Have a junction box with two red wires, one white wire and no ground wire coming in. How do I wire to an outlet to provide a 110 outlet for a cook top?

One single cable runs from the circuit breaker to a junction box in that area of the house.
The cable has a black Hot wire, white Neutral wire, and bare ground wire.
Once the cable arrives at junction box, it can split up 2 or 3 directions.
Each successive box receives a cable that feeds back to the first junction box.

Chances are the junction box is on the ceiling. And it will be the ceiling box that is closest to main breaker box.
Junction box can also be a switch box. In that case it will be switch box closest to main box.

Find the junction box, as point of organization.
Open junction box and separate all black and white wires.
Turn power on and see if breaker sets.
That will tell you if problem is between main box and junction box.

Junction box wires are separated.
Tape tester leads to wood sticks to keep hands away from power.
Turn power ON and test each wire in junction box to bare ground wire.
Tester will light up on Hot wire.
Test Hot to each other wire in box, except bare ground, and tester lights up on Neutral
This identifies the cable that comes from breaker box.

Now, reconnect cable from breaker box to one of the other sets of black and white wires located in junction box.
Check if breaker resets.
If breaker resets, see what circuits are working, and you can eliminate them as suspect.

Remember each successive box in a circuit has 1 cable that connects back to main breaker box
Going 1 box at a time, and disconnecting black and white wires, will eventually lead to the suspect.

Early installations grounded the neutral line at the transformer, but did not bring in a direct ground wire as required for modern installations. White is neutral and should be connected back to the transformer secondary center tap. You will need to drive an 8-foot grounding rod near the panel and bring the ground connection into the box grounding bar (tied directly to the box as opposed to the neutral bar which is insulated from the box). Red and black wires are for 220 volt connections back to the transformer and feed each breaker on that particular rail with 110 volts. Any dual 220 volt breaker will contact both vertical rails. Each light and outlet in the house should have a ground connection, a neutral connection, and a 110 volt connection. Always place a switch to interrupt the 110 volt connection, not the neutral connection. You will likely need to measure the voltage across the suspected two hot wires to confirm the incoming 220 volt lines. Hope this helps!

If your box contains 2 and only 2 wires, then the Utilitec timer will not work.
You need the Intermatic ST01C or EJ500 timers that operate with a battery.

I have tested the Intermatic and Utilitec timers:

http://waterheatertimer.org/ST01C-program.html#wire
Do not connect white and red wires together on any timer, but thank you for solving the problem why lights blink when connecting timers.

Now lets look at your wires.
Scrape paint off the wires so you can identify white and black.
According to your information, the black wire inside box will connect to timer-black wire.
The red wire always goes to Load (your light, fan, motor)
The white wire is necessary to complete a circuit so the clock inside timer will operate.
The timer has a clock just like your alarm clock, and it needs to connect back to neutral busbar in breaker box.
This is why the battery-operated timers will work with two wires, the clock runs on battery.
The Utilitec timer-white wire is the wire that goes to Neutral
The timer-white wire is supposed to connect to the other white wires that are twisted together and covered with a wire nut ... but some boxes do not have this neutral wire
To work-around, the timer-white wire can also connect to a bare ground wire.
The bare ground wire also connects to Neutral busbar in breaker box

If you do not have a neutral or ground wire as described above, then you need the battery-powered ST01C or EJ500 Intermatic timers.
See if you can pull some more of the wire into your box ... there might be a ground wire that was cut off and pulling more wire might reveal a ground wire. This will salvage the project.
Aplus is one of many places that sell the Intermatic timer

The timer should have red, black,blue and green wires. (no white?) If you have only the two black wires coming from junction box, then connect green to ground like you did. Connect the incoming black (HOT) to the black wire on the timer.connect the outgoing (to the light) to the blue wire on the timer. Cap of with wire nut the red wire. This is for a single pole switch installation (Only switch for the light) If this is for a 3-way control (where you have 2 or more switches) then you use the red.

Yes everything would work perfectly. I see no problems in your plan. Even if both fans were run off of one switch they would not burn out, the circuit it appropriately sized. You could even go a step down to save yourself some money and use 14/2 and 14/3 (supposing its only the fans running on the circuit). You can run up to 16 amps on 12 AWG wire and up to 12 amps on 14 AWG wire (80% of breaker tolerance). Also when it get to the fans use a wire junction box run your 3 wire cable in there and branch out to your fans from there with separate 2 wire cables. I believe that was your plan just wanted to clarify. Good luck!!

This sounds like you should call an electrician, or someone that knows wiring. Red and Black are both hot, White is neutral, and Green is ground. Remove the ground strap from the center of the terminal block to the case. Put green wire to the case, white in the middle, and red or black to either side. Your last question I do not understand. But it sounds like you need an electrician to connect a 4 prong receptacle, with the proper 4 conductor wire to your breaker box.

white and ground are grounds there should be a ground rial in the fuse box, stove is 220 black and red go to 2 seperate breakers, 25 amps, and 15 amp is for 110 regular outlet

Two options,

1) get a three wire outlet ("plug in")
2) get a 4 conductor cable.

The 4th wire is green or bare - ground the wire to the cabinet.

You are 'safer' with the 4 conductor wire. (In the past, White served as the neutral conductor and the case may have been 'bonded' to the white, providing a "ground". Today, I believe the code requires a separate ground. Even though the white and green join in the service panel and go both to ground and "back" to the utility, there is the possibility some installations are wired through a sub panel. Common use of white as neutral and ground is not allowed in a sub-panel in most jurisdictions). Black to black, Red to red, White to white and Green (or bare) to the frame. You can make a hole and connect it or use an existing screw that is nearby to make the connection.

If you have a volt meter, you can check your existing outlet. You should get 220 V between the two legs, 110 V between "red" and "white", 110 V between "black" and "white", 110 V between "red" and "ground", 110 V between "black" and "ground", and no reading between "white" and "ground".

The terminals on your existing outlet should be clearly marked and the color code of the wire should be clear although it is POSSIBLE the color of the conductors is all black. The above series of tests will help you determine what is what if necessary.

If you are still unsure, you should get the advice of a licensed electrician in your area (which I am neither)

I hope this helps you

a

if you have220/240 across the house black wires put red from stove to one black then black to blackaluminum to copper should be the ground turn breakers off after you check the volts across the black and the ground make sure the ground is a ground and you will need to run a white wire back to the breaker box for the neutral then white to white

those wires dont go to the down draft. those colors are to hook up the stove. do you have the instalation instructions?
