What is involved in installing a new 240V breaker in the main breaker box so you can add a 240V receptacle?
* A 240V double-pole breaker of the right size for your load, (Don't try and use two single-pole 120V breakers!) and the right type for your box (SquareD breakers for SquareD boxes, GE for GE, etc.)
* A length of 4 conductor wire to run from the breaker panel to the outlet that is the right size for the breaker! Rule of thumb for wire runs under 50ft: 14 gauge for 15A, 12 gauge for 20A, 10 gauge for 30A, 8 gauge for 40A, 6 gauge for 50A, etc. Get 4 conductor wire even if you only want 240 (and not 120) for futureproofing.
* A new outlet and box to mount it in.
* Clamps to secure the wire to the box and breaker panel.
Then you need to:
* run the wire from the panel to the outlet. Leave slack at the panel, you need a couple feet inside it.
* Wire the 240V outlet. Remember the color code: the black/red/brass screws are for the black and red hot wires, the white/silver screw is for the white neutral, the bare/green screw is for the bare or green-covered ground wire.
* One slip and you're dead. So always shut the breaker panel main switch to OFF.
* Connect the wires into the panel. Which bus is which should be obvious by the existing wiring. Remember to get your connections good and tight.
* Put the covers back on everything, switch everything on and enjoy.
If anything I said above wasn't obvious, buy a book. It will explain everything better than I can in text and serve as a handy reference on the job. If you are still not confident, hire a professional licensed electrician.
Some things to remember are:
A - You must kill the whole box before jumping in it. KILL IT.
B - never grab more than one wire - or contact - at a time!
C - Try not to ground yourself out.
D - always use the right size wire for amperage needed.
E - You do not have to be a brain surgeon to wire in a circuit. If you are not totally confident with what you are doing definitely consult someone who will be nice enough to give you life saving tips instead of telling you to take a hike.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

If you have a breaker that has a 120240v and your dryer has a 240v plug can you change the receptacle to a 240v?
What size wire do you use to install a 100 Amp breaker for a 240V receptacle for use with a 240V range?
How can you wire one half of a 20 amp 120 v duplex wall socket to run 240 volts over 2 legs 2 separate 120 v legs?
You can't. I'm not sure exactly what you're trying to do, but the way it is written is not possible. It seems you might want to use half of a duplex receptacle for 120 and half for 240. This would not be code compliant, nor would it make sense. A plug designed for 240v will not even fit into a 120v receptacle. You need a 240 volt receptacle rated for the amperage you will need…
If the 2 hot wires are connected to either side of a receptacle, you have a 240v receptacle (assuming it's in the US). This is typically done for window air conditioners. But code requires that the receptacle have a different configuration than other receptacles in the building so you don't run the risk of plugging in a 120v device into a 240v receptacle.
How do you safely connect to a 240V pullout fuse box used for pool equipment located in a detached garage as a temporary power source for a 240V millermatic 250 mig welder?
== == == == Don't know if there are any 240V GFCI receptacles so I vote for a 240V GFCI breaker which would be 2 pole. The pump should have two colored wires and a white. White goes to the neutral bus and the two colored wires go to the two poles of the breaker. <><><> As always, if you are in doubt about what to do, the best advice anyone should give you is…
If installing several base board heaters with various watts what is the max number of watts you can put on one 20 amp 240v breaker?
The 30 A breaker you seem to be describing is a 240V breaker. There should be two black wires or perhaps a black and red wire connected to the two screws on the breaker. So the breaker would trip if more than 30A was demanded by the load with 240V across the load. What you have connected to the breaker should be sized such that the total current is no more than 80% of the…
If you have a 240V dryer and installed 30A breakers on both sides of the line reads 120 and 120 how do you get 240 and you have a receptacle that reads 30A 125250 and still does not work?
you do NOT put two 110v breakers in. you put 1 two pole breaker in. the panel is designed to give you 220v off one side OR the other side if you use a 2 pole breaker on one side or the other side. If you look at both 120V lines on an oscilloscope you will notice that they are both 120V to the neutral, but they are 180 degrees out of phase. This means…
If you have a sub-panel in the garage already then the job is fairly simple. You will first need to figure out approxiametely how many amps your will be drawing from that receptacle while using your tools. You'll need the following material: A double pole breaker to match your panel (with correct amp rating to match your receptacle and cable), A 240 volt receptacle (with correct amp rating), and two conductor cable (12-2 or 10-2…
240v nema6-50r outlet wired with 6 gauge wire and 50 amp breaker you need to run a heater with a nema 6-30p can you simply put a 30 amp receptical in place of the 50 amp receptical?
First off, this is for a single phase 120/240V system only. The ground and neutral can be bonded at the receptacle but not instead of bonding them at the panel.You should always have them bonded together at the panel in a single phase 120/240V system. Otherwise you risk having a floating neutral in your system.
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 can you plug in 120V appliances such as a TV and VCR to an old 240V air-conditioning outlet with one white one black and one grounding?
At the breaker box the black and white will be on a double-pole breaker (or maybe even two separate breakers). To convert to 110V attach the black to a single pole 15 amp breaker, the white to the neutral bus bar (like all the other whites in there) and the ground to the grounding bar (like the other grounds). Then replace the receptacle with a regular 15amp 110V.
This is a very simple procedure, but the fact that you ask the question indicates you should get an electrican to do this simple job. The installation is fairly simple. Its the calculations involved (for proper wire size, overcurrent protection size, etc) that require some electrical knowledge. I'm no expert on welders, but I know they can pull some massive amperage. Leave this one to the pros, or you could very easily cook your house.
It's the same receptacle, except L6 is 240V rated vs 120V rated for L5 (note: The answer above is incorrect. It is true that the L6-30 is a 240V rated connector, and the L5-30 is 125V rated. However they do not share the same pins, they are similar, but one connector will not mate with the other receptacle.)
How do you convert a 120V receptacle to a 240V receptacle for a European stereo system that uses 230V if the Stereo has no toggle switch to 110V like some units on the market?
You can't "convert" a 120V receptacle into a 240V receptacle. A proper new 240V branch circuit complete with correctly sized circuit breakers, wiring and socket outlet is required. For more information see the Related Question shown below. <><><> As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

No, a single breaker provides only 120 volts to a circuit. If two adjacent distribution panel breakers are terminated in the same box there will be a 240 volt potential there. A kitchen counter is an example of this type of installation. It is called a split receptacle where there is a full 15 amps on the top half of the duplex receptacle and a full 15 amps on the bottom half of the duplex…
You will need to have a three wire feeding your well pump motor to do this. It will be connected like a sub panel breaker box. A new breaker for the pump out of the new panel and a 15 amp breaker for the new receptacle. Both of these circuits must be protected by their own breaker. <><><> As always, if you are in doubt about what to do, the best advice anyone should give…
What is a reasonable price for an licensed electrician to install a 240V 30A receptacle in the garage for a dryer 10' from the panel in San Diego California?
Whatever the market will bear. If a guy is charging too much, get someone else. The real issues are things like accessability and how much space is in your breaker panel and how large is the electric service into the house. If your breaker panel is full and you need more space the electrician may need to put in a larger panel. Too many questions, not enough information to answer your original question. Sorry.
How am i getting 240v between hot and neutral I recently moved into a new home and my washer dryer receptacle was getting 240 from hot-hot 240 between hot1-neutral and 0 between hot2-neutral... help?
I presume that you are testing the receptecle. If so and you are probing one hot lead and one of the 2 neutral leads the receptecle is wired incorrectly. Present day 4 slot receptacle have 2 nueetrals and 2 hots. 110v should read over both hots to groun, and 240v between the 2 hots. Hey Steve its actually a 3 wire plug, the older style and the receptacle is wired properly, i tested it at…
Not directly. You would either need to step up the voltage using a transformer or have a 240V receptacle installed. Most homes are actually supplied with 240V in North America which is split to produce two separate 120V legs with a Neutral Center Tap. The voltage between these legs, however, is still 240V.
s for USA, Canada and countries using similar 60Hz mains supplies Conversion Dangerous and NOT Recommended Ummm no. If you did try to do it, you'd have a pretty good chance of burning your house down. More Information: I want to say "no" you can't do this based on what you've told me. What matters here is the size of the wire, 240V is 240V and that part of it doesn't matter. A dryer uses…
It would have to be a 30 amp breaker to use the full power of the welder. I'd say go with the 30A. The general rule is that your planned load should only be 80% of the circuit capacity. That means a 30A circuit should have a maximum load of of (30*0.8) = 24A. With the 30 amp breaker you must have at least #10 wires feeding the circuit.
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…
