More information is needed. What does the manual say you need? With out the necessary details needed to help I would assume it is 220V. Run a 4 conductor cable. It would have two phases (115 to neutral each) a neutral wire, and a earth wire which is connected to the cabinet. If this is confusing you best get an electrician to do it for you. If you mess up you could cause your facility to go up in smoke.

SOURCE: electric furnace wire heating up

you should have a 3- conductor # 6-3 copper wire running to this 60 amp breaker @ the furnace to the panel if this is not the case you should replace this with a # 6 as of now as it is a fire hazard as it is and needs to be fixed at once , # 10 -2 wire is only good for 30 amps and a 60 amp breaker will not trip under fault condition and you could have a fire , if you need further assistance on this let me know and i will try to help

SOURCE: 1 question can Cutler Hammer breakers have the

There seem to be several questions mingled in with those 2 questions.

1) Amps can go either way

2) Breakers trip when heat exceeds certain level. Heat is caused by amps.

3) You want to add a subpanel in garage.
I do not know the code in your area for installing a subpanel.
Your plan will work by connecting 6 gauge wire to main breaker, and new 60 amp breaker will protect wires between main box and subpanel.
Remember, wires going into main breaker cannot be turned off without pulling meter.
Some areas require license to pull meter.
http://waterheatertimer.org/How-to-replace-circuit-breaker.html

4) To work around license and meter-pull, simply replace a 240V breaker in main panel with your new 60 amp breaker.
Then move breakers around to match new set-up.
New subpanel can accommodate two new 240V breakers and one new 120 Breaker
http://waterheatertimer.org/How-to-install-a-subpanel.html

5) 6 gauge wire is correct for 60 amp breaker.

6) I'm not sure what you mean by the box rails?

7) Do you need more amperage on main service?
This means adding a larger service panel with 150 Watt or 200 Watt main breaker.
Some areas require service upgrade when remodeling or adding circuits.

8) How to figure total amp draw at your house.
Add up total watts being used.
For example you have 1/2 Hp motor
754 watts per Hp
1/2 Hp = 377Watts
Volts x Amps = Watts
Amps = Watts divided by Volts.
377 Watts divided by 240Volts = 1.57 amps (plus a bit more amperage when motor starts)
40 watt light bulb divided by 120Volts = .33 amps
Double oven has label located inside door that shows upper and lower wattage.
Dishwasher, dryer, big screen TV, satellite receiver all have labels that show wattage.
Water heater has label that shows wattage of each element.

SOURCE: Can I remove a breaker from panel box cap the wires turn electric back on till I go get a new breaker.

yes, you can... preempt removal with a recheck that there is no power getting past the main breaker switch. I should have shut off the main circuit breaker as well. You see, I had a "situation" where as a Journeyman plumber, I started a water heater repair with turning off, just the electric water heater's 30 amp circuit breaker switch. when I went to replace the leaking water flex pipe on top of the tank, electricity threw me across the garage! What had happened was, the breaker panel's main copper ground wire, was loose where it was attached to the outdoor "ground spike" which is usually driven deep into the ground. The homeowner had been smaking it with his lawn mower for years and loosened the clamp. SO, when I was standing in the leaked water, and touched the pipe, I became the "main ground" for the house!! Very soon after, I purchased a "touchless" AC field tester. You just hold it close to the wire, even with insulation on it.
It will beep or turn on a light, to let you know if there is power or not.
They are great for finding electrical "breaks" inside of electrical wiring insulation too!!
Be sure to turn off any computers, or other electrical appliances, that might be harmed by a momentary "spike" in the power, when power is restored.

SOURCE: i have a 440v 50 amp and a 220v 30amp main breaker box outside my house. the 440 goez to the inside of the house and i have to unplug the 440 and plug in myown 440 plug i connected to another breaker

Some of these numbers don't make sense?
I have Never heard of 440v and 220v in a residential application, they are two different systems, 480 volt is typically 3 phase power, and 240v is typically single phase, more in likely you have a 200- 400 amp main service, and a 100- 200 amp secondary service for the welder, that can't be 110 @ 200 amps?
I would need more info, and pictures of actual nameplates of the equipment,
and then I could advise a safe NEC electrical code answer...

How do I wire 110v from a 220v box?

You have two wires in the box that will read 220 plus
volts to the ground wire,the box if grounded & to the
white neutral

So pick one of those wires,(black or red ) for your short
recepticle slot & gold screw & the white neutral goes to
the silver screw & longer slot

Put a wire nut on the other 220/240 wire, if it isn't going to be used

Have to ID the breakers for the wires first & know what is on
those circuits.

Will need to change the breaker out if your running a dedicated
120 volt circuit & then you will have an open space you will need
a plastic cover for, when you remove the 2 pole breaker

I have a new furnace and the breaker keeps tripping (20/30). It is a bryant westinghouse box. I think 200 amphes

1) You got a FIRE truck coming.

2) Wire is too small.
Problem is NOT circuit breaker.

3) Both 240Volt appliances on same breaker is a hazard, especially if space available in 200 amp service panel for more breakers.

4) Usually each 240V appliance has separate breaker.

5) Circuit breaker trips because of High heat on the wire.
If wire gets hot, it will start a fire inside the wall.

Electric code requires wire-size match breaker-size.

6) If you put larger amp breaker on same wire that is getting hot, then wire will get hotter.
Result: FIRE truck middle of night with folks jumping out window in glass-cut bare run across yard.

7) Each appliance has volts and watt rating on label.
EVERY appliance has label.

8) For example stove might be rated 8000 watts and 240Volt.
8000 watts divided by 240 volts = 33.3 amps
Stove would require 40 amp breaker and 8 gauge wire.

9) How to figure it out:
http://waterheatertimer.org/Color-codewire.html
http://waterheatertimer.org/How-to-install-a-subpanel.html

10) Do same calculation for new furnace.
12000 watt furnace divided by 240 volts = 50 amps.
Use 60 amp breaker and 6 gauge wire.

11) Summary: fixya wants you to be safe, and buy stuff showing in the ads.
Use a bigger breaker ONLY when bigger wire is also installed.
Call furnace installer, the installer should know to check safe wiring before installing.

I have a maytag performa electric dryer with no heat, checked fuses, replaced heat element and thermostat, any ideas

Have you checked to make certain you have the proper voltage where the dryer is plugged in? 220v? A dryer will run on 110v but requires 220v to heat. Could be a problem with the breaker in the breaker box. If you are not familiar with electricity, I suggest you find someone knowledgeable ie professonial

Triing to install intermatic t103 please help. Source is 3 wire 110v want to run 3 blower 110v 9.5 amps each off the t103 timer. Don't have 220v in house just 110v. I need a very simple wiring diagram I...

T103 has 120Volt clock motor, so we can wire this timer.

T103 timer is rated for 30 amps and 2horsepower and your blowers use 28 amps.
So we're getting close to max on the timer. Hopefully blowers won't all be started at one time since motors draw maximum amperage when they start.
However, you need 30 amp breaker and orange 10 gauge wire for that much amperage >> unless only one blower is turned ON at any given time.
Always match wire size, amperage of breaker and amperage of Load or it will trip the breaker.
If you put 30 amp breaker on size 10 wire it is good. But 30 amp breaker on smaller size 14 or 12 gauge wire is fire hazard.

Look at the basics:
You have 2 cables.
One cable comes from breaker box.
Other cable goes to three 120V plugs (120V is same as 110V).

Each cable has black-wire, white-wire and bare-copper-ground-wire.

How to wire the timer.
Timer has 5 terminals: A 1 2 3 4

A) Cable from breaker box:
White wire from breaker connects to terminal A
Black-wire from breaker connects to terminal 1

B) Cable going to 3 plugs
Black wire to plugs connects to terminal 2
White wire to plugs connects to terminal A
Ground wires connect to green ground screw.

Terminals 3 and 4 are not used in this case.
Here is a wiring diagram that shows 120Volt from breaker box and 120Volt going to Load

I am trying to replace a electric baseboard heater that is 220 volts and I am unsure about the wiring. the heater has a red and black wire and there is a white and black wire coming out of the wall.How do...

if you have a electric meter check the voltage coming out of the wall to be sure it is 220 v???? (meter across black and white)then with your meter only test black wire to ground and white wire to ground seperately you should have 110 from each wire to ground?
If you have only 110 to the black and no reading on the white, you either have a bad breaker or a 110v circuit
If you read 220v and you new heater is rated for 220v black to black and red to white wall thermostat or built in as long as you have 220v to your connection from the wall or your wall thermostat when turned higher than room temp.
Bare grounds tie together and mount to your green ground screw

Where is the circuit breaker or fuse on a Kenmore Gas Dryer?

no heat usually means your only getting110 volts into your dryer.....you need the full 220volts to run heaters....with voltage meter you checkwires on the plug OUTLET...or inside back cover REDwire to WHITEwire =110v.........BLACKwire to WHITEwire =110v.....REDwire to BLACKwire =220v. you probably have aBAD 220V. 30 amp circut breaker..or if still using FUSES one is burnt out (In house electric panel) or burnt off RED or BLACKwire in back of dryer.....

Hooking an electrical dryer to a breaker

You will typically need a 40 amp 220V circuit for this ( check with local building inspectors).  You will need to run some hefty wire probably #8 three wire  (again check) and install the type of plug receptacle that is on the  dryer cord.

Inside the breaker box you will need a dual breaker 220V breaker rated at 40 amps.  The wire coming into the breaker box will need to be clamped in place with appropriately sized wire cable clamp where the enter the box through a knockout- available at any hardware store.

 

Now the big question-  why are you switching to electrical?  Gas is pretty much half as expensive as electricy  and will dry the clothes faster (usually gas dryers generate more heat than electrical ones).   Just wondering..
