If you have a four-prong 240V outlet can you switch the outlet to a three-prong 240V outlet?
The 4 prong receptacle should be more in line with the latest wiring code. It is best to change the plug or the cord on the appliance you wish to use. If you have a 4 prong outlet, the purpose is to isolate the neutral from the ground.
There are numerous examples mentioned in Wiki s but they all amount to requiring that there be no link between the neutral terminal of the device [appliance] and the frame.
It is, however, allowed [by the NEC, unless disallowed locally by the "authority having jurisdiction"] to install a link to the neutral terminal from the chassis if there is already a three prong outlet existing.
ALWAYS CHECK WITH YOUR LOCAL WIRING SAFETY OFFICE BEFORE YOU ATTEMPT TO CHANGE ANYTHING ON POWER MAINS OUTLETS
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
If you do this work yourself, always turn off the power
at the breaker box/fuse panel BEFORE you attempt to do any work AND
always use an electrician's test meter having metal-tipped probes
(not a simple proximity voltage indicator)
to insure the circuit is, in fact, de-energized.
If the 220V circuit is dedicated, is to derate the circuit to a dedicated 110V outlet. Replace the 220V breaker with a 110V breaker and install a 110V outlet in place of the 220V outlet. If the original circuit was 20A or greater go with a 20A breaker and a 20A outlet as Airconditioners are fairly large loads. Do not exceed the current rating of the old circuit as that is all the current the…
An existing outlet can be converted by replacing the 30A circuit breakers or fuses in the circuit breaker or fuse box with 15A breakers or fuses. The 30A outlet should also be replaced by a 15A outlet. This is all that is required if the wire from the supply to the outlet is 10, 12, or 14 guage. The existing wire should be 10 guage wire to handle the 30A and there will be no…
Can you convert an existing 120V plug on an appliance to a 240V plug not speaking of a converter but actually changing the plug so there are no long term effects on the appliance?
If I understand your question, Can you run a 110 appliance off of a 220 volt outlet? You could by only using one leg of the 220. You may also consider changing the outlet. Put in a regular 110 outlet and capping off one leg of the 220 in the wall box. You still have a neutral and a ground to work with. I read this as the questioner doesn't want to modify the outlet…
You really cant do it because a 220 has a heating element in it to dry the clothes unlike gas that uses fire to dry the clothes and the 120 is to turn the drum.Your drier will keep poppin breakers which isn't good at all. Outlets and Power (110V outlets and 120V outlets are practically the same for this discussion. I will refer to them as 120V. Same with 220V/240V outlets.) By 110V outlet I'm…
How can you convert a 3-prong 240V appliance outlet to 120V without rewiring and replacing the outlet?
For USA, Canada and countries running a 60 Hz supply service. 1) An outlet for 240V is totally different from a regular 120V outlet. 2) The wiring for 240V is also much heavier than for 120V. 3) The double pole circuit breaker necessary for 240V is different to the single pole breaker used for 120V. 4) Anyway it is not clear why you would want to try to change a 240V outlet to a 120V…
Can you get an adapter if you have a 240V outlet that accepts 3 rounded prongs and you have a 240V air conditioner that has 2 straight prongs one vertical and one horizontal and a gnd?
What's the reading at the service panel? What do regular 115V outlets read at? What kind of meter are you using? Chances are you have 480/277V 3 phase power to this building. Whoever wired the outlet used a 277V feed, possibly because 240V was not avaliable. You should call an electrician, repair of this problem may involve instalation of a transformer.
Probably, because a "220V dryer" and a "240V dryer" might be the same thing if you're in the United States. Most electricity in the U.S. can vary within about 5% of 120V (114V to 126V) for single-phase, two-wire current (commonly called "110"). For single-phase, three-wire current (split-phase current, commonly called "220"), the voltage can vary within about 5% of 240V (228V to 252V). So, as long as the holes in the outlet and the plug…
I cannot think of a scenario where you would. 240v in the US has 2 hot wires and, if there is a switch, both wires must be switched. What you need is called a disconnect, which is larger than a switch and in its own enclosure. These do not come in a 3-way configuration. A disconnect is not intended to be operated under load, which is with the equipment turned on.
How can you wire a 110V plug outlet from a 240V plug outlet not speaking of a converter but actually changing the plug outlet so that there are no long term effects on the 120V appliance?
How do you hook up a 15 amp 240V outlet which only has three terminals to 240V wire which has two hot wires a white and a ground?
Before working on this circuit be sure that the power is turned off. First the breaker that will be feeding the outlet should be a 2 pole 15 amp breaker using at least a #14 wire. Since this is a 240 volt install you will not be using the white wire. Tape it off and push it to the back of the outlet box. Take the 2 hot wires and connect them to the two…
A 6-20R is 220V, 15/20A correct? If the outlet is within 75ft of the panel you need to run 12-2 to the outlet from the panel. I would recommend 12-3 as you can then upgrade to a 120/240V outlet later and you are not using a white wire as a hot. If you do use 12-2 wrap the white wire with electrical tape to show it's not neutral. Then just wire the outlet as a…
Do you need to replace a 240V outlet for the stove if it makes a cracking sound when the stove gets turned on?
Could be the outlet, could be an open wire, could be a loose connection. First thing I would do is check that the connections are tight. Then replace the outlet. That leaves the wiring... The connection is probably corroded. Check the plug, if it's black and pitted you probably should replace both the plug and outlet.
minimum 230volts In formal electrical jargon, a "device" does not "use" electricity. A device is something like a switch or receptacle(outlet) that helps control or carry electricity but does not consume electricity. In the United States, voltage for home lighting and general purpose receptacles is 120v. Voltage for electrical appliances such as ranges, clothes dryers, or furnaces is 240v. Voltages such as 110v, 115v, or 125v are versions of 120v in electrical jargon and voltages…
