My oven 240 volt outlet plug is showing 120 volt on one of the power legs when the 40 amp switch is switched off. We keep burning out oven parts. We replace the 40 amp switch and are seeing the same thing. It has a 3 prong plug. Any ideas?

First confirm that you have current available on the 120 leg by trying a lightbulb (use the ground leg for your neutral). A meter can show 120V even if there is just a slight leakage, but no current available. If the bulb lights (with the two-pole breaker off) then you have a wiring error. Find our which other breaker is supplying that 120V through a process of elimination. You might also confirm that the 40A breaker actually does turn of both legs by checking the output lugs of that breaker with your meter. Put one lead on a lug and the other lead on the neutral. Repeat for the other lug. Good luck!

Check your local codes, you probably will need a ground fault current interrupting breaker(GFCI). Do not skip the codes, if anything goes wrong, your insurance company will not cover. Putting a special box GFCI protected will give you extra protected outlets for outside use.

SOURCE: 15 AMP versus 20 AMP outlet plug

The circuit is protected by the 15 amp breaker. That's what matters, the wire size and the breaker feeding it. It's OK to have a 20 amp recepticle fed by a 15 amp breaker.

SOURCE: tried replacing a 2 pole

You are correct. Try replacing the single pole breakers with thinner space saver breakers to get more space in the pannel.

I have a 12 inch chraftsman table saw with 2 wires coming from motor. The wiring diagram inside the cap shows it to be wired for 240 how do I wire that thru a switch and to a three wire recepticle

Not quite sure what your question is - Are you trying to plug a 240 into a 110/120 outlet? Or are you trying to plug this into a 240 3 prong outlet?

Traditionally, table saws don't come with a power cord - you must supply one. Usually on the motor there is a metal plate that describes volts/amps/phase/hp etc. Get the Volts/Amps from this plate, then measure the approximate distance between your table saw and the 240 outlet. The gauge of the power cord depends upon the Volt/Amps and the length of the cord. There are many volts/amps vs length for wire gauge conversions on the net. I always get a bigger wire (smaller gauge) than what is recommended. Expect to pay $100 or more for the cord (don't be cheap here). If you have an under rated cord, you can start a fire, burn up your motor, melt plugs into outlets and have to replace the outlet (don't ask how I know).

I'm a little suspicious of the "white and black" wire from 240 - it's usually "white and red" with a "black" ground. 240 is made from two 120's - opposite sine wave. So black is usually the common ground, while the white and red are the two 120's. Volts between white-red=240, white-black=120, red-black=120. If you're absolutely sure that white-black=240, then you can just connect a ground wire to the motor case. Many home table saws can be wired for 240 or 120 - you need to make sure that you're hooking 240v to the correct wires. If you're uncertain at all, then don't do it.

I have wired 120 to a 240 motor by accident and the motor ran - it had no power and didn't spin at full RPM. You can damage a motor this way, so I wouldn't recommend it. I have never put 240 to a 120 motor - so I don't know what happens (guessing you could burn up the motor coils).

With all that being said, if you have 240 outlet with 3 wire receptacle, then just use a multi-meter to determine the 2 "hot" and the 1 ground. Volts from hot1-hot2=240, hot1-ground=120, hot2-ground=120. If you don't have a multi-meter, buy one (approx $12). Once you have it wired up, then try the motor by flipping the switch on then off again. If the motor didn't spin, then you did something wrong. If it hummed but didn't spin, you have some connections wrong inside of the motor. If it spins the wrong way, then your wiring inside of the motor is wrong (doesn't help to flip the wires on the outlet). If you blew a circuit breaker, then the wiring to the motor is wrong.

Not getting hot

first make sure theres 240 volts at the dryer plug in ,if not then try resetting your circuit breaker ( or fuses ) if its electrically heated (not by gas) and is plugged into a 240 volt receptacle as even though the breaker may not show its tripped by the little orange window on the breaker it can lose one phase of power ( 120 volts) and still turn but it needs both phases to operate the 240 volt heating element,if you lose one leg of power ( 120 volts ) either the drum will turn or the timer will run (but not both ) because each of these parts only operate on 120 volts or one leg of the 240 volts

I have a Kenmore electric range with burners not a flat top. The clock and the oven light work. The ovven and the burners do not work. I have reset the breaker. Could one side of a breaker burn out? Thxs

Yes, one side of a double pole circuit breaker could go bad, but unless you live in a really old house it isn't likely. Instead of just replacing the circuit breaker, $30+, you might want to check with your neighbors and borrow a multimeter to check the outlet to see if you have 120 volts on each leg of your outlet (which makes up the 240 volts you need). If you have 120 volts on each leg then your breaker and outlet are functioning.

Some ranges have an internal fuse that controls the heating elements. Suggest you go to and plug in the model # off the equipment id tag (on rear panel or on oven frame) and check to see if there is a fuse or fuseable link.

I have a electric dryer Model WED5810SW0 THAT I WAS TOLD I COULD CONVERT TO 120V from 240v is this true and if so how do i do this?

If you consider doing this the first thing is SHUT THE MAIN BREAKER OFF. Use an auxiliary light source to see when working in a dead panel. Always keep in mind an ARC FLASH ACROSS HOT MAINS HAS ENOUGH HEAT TO PEAL THE SKIN OFF OF YOU. Before an explanation of how to do it you should keep in mind that this is for a single receptacle only. If any other receptacles are on the same circuit they will also be changed to 240 volt receptacles and if you plug any 120 volt device into them, the 120 volt device will be destroyed. That said OK, any 120 volt outlet can be changed to 240 volt by removing the 120 volt circuits neutral, re identifying the white wire with red or black phase tape and connecting it to a new 2 pole 15 amp breaker. The maximum that this circuit will now load up to is, on #14 wire at 80% = 12 amps at 240 volts. The 120V receptacle must be changed to a 15A - 240V receptacle so that 120 volt devices can not be plugged into it. Never use 2 single pole breakers together because code requires that on a fault trip both legs of the 240V circuit must be disconnected simultaneously.

Voltage converter buying guide. Voltage Transformer Buying guide.Voltage converters also known as voltage transformers are devices that convert foreign electricity to power devices from different parts of the world. A step down voltage converter is a 220 to 110 volts converter. A step up converter is a 110 volts to 220 volts converter. Our 2-way converters are voltage transformers that convert power from both 220 to 110 volts and 110 to 220 volts. They also work with 100 volts, 110 volts, 120 volts, 220 volts and 240 volts.

How do I know if my Hotpoint oven 920 years old0 is on a 220 0r 120 line? The serial plate says 120/220.

An oven uses both 120 & 220 -- actually it would be 120 volts and 240 volts or nominally, 110 volt and 220 volt.

The 120 is used for the lights. The 240 is used for the heating elements.

A 240 volt breaker (nominally 220 volt) -- supplies both 120 and 240 volts depending on how the supply is connected to the appliance.

There will be a 240 volt (nominally 220 volt) breaker in the main panel for the oven. This is two 120 volt breakers side-by-side with their toggle switches connected together with a strap across the top of the toggles.

My Altoshaam keeps burning out the on off toggle switch on the top section.

Ok i assume you have the 208-240 model not the 120 model, when you said 2 legs. at 240 volts its max draw is 8.3 amps on each leg, even with the 120v model, the max is 16.0 amps.

so yes your heating coil is if you have 18 amp draw..that is your problem....

Apartment size brentwood electric range. The oven, 2 timers to the right of the clock and the outlet on front left have stopped working. Clock works, all top burners work.

Some of these ranges have two plugs, one for 240 volts for the burners themselves, one for the controls. Other issue, could have one leg of the 240 volt circuit not working, might get some heat, but not full power. Check fuses, just to be sure. In any event, you likely have two circuits: 240 volts for the power required to take care of the heat, and 120 volts for controls, timers, clocks. If only one plug, I'd expect to find a blown fuse within the appliance, or some other problem in the 120 volt circuit.

Not sure of your level of expertise to open up and trouble shoot electrical. Need to understand (1) how to kill power and (2) how to safely test a live circuit (at 240 volts.) Make sure meter is always set to 250 or greater volts, AC.

Low heat 100 degrees

either the cycling or hi-limit switch are bad or the element is open or the neutral wire can burn open or you could have lost one leg of power to the dryer so instead of 240 volts its running on 120 volts,the motor and timer run on 120 volts even though they are normally on opposite sides of the 240 volt circuits,chk the power to the unit first for 240 volts its the easiest test

Electrical wiring for 120/208 service as opposed to 120/240 service

Your machine requires 208-240 volts to operate with each leg being about 120 volts. Move refrigerators are 120 volts so even though you have 20 amps you probably only have 120 volts.

You can go to the Bunn website ( click on Commercial then on Publications then Illustrated Parts and Service manuals and download the manual for your machine that shows how the wiring hooks up in the machine and the type of cord the machine requires to handle the voltage.

The plug you need must match the receptacle in the wall and there are numerous 220volt plugs and receptacles on the market. Don't get a dryer plug instead try for a twist lock as they are more reliable.
