for USA, Canada and other countries running a 60 Hz supply service.You are going to need a number of things:

* 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.

Negligence with electricity is fatal.

Addendum

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 ARE NOT ALREADY SURE YOU CAN DO THIS JOB

SAFELY AND COMPETENTLY

REFER THIS WORK TO QUALIFIED PROFESSIONALS.

What size wire do you use to install a 30A breaker for a 240V receptacle for use with a 240V air conditioner?

10/3 with ground NM.


How do you change a double pole 240v breaker to a single pole 120v breaker to allow a regular 120v receptacle to work?

What size wire do you use to install a 100 Amp breaker for a 240V receptacle for use with a 240V range?

A 100 amp breaker is too large for the average range. If you meant 100 amp service panel then the following installation will work. The most common size breaker used in North America for an electric range is a two pole 40 amp breaker. The feeder to the range receptacle will be a #8 conductor.


Can I run a double 30 amp breaker with 10-3 wire to receptacle for 240v MIG welder. Distance from main box to destination is 60 feet.?

Yes.


Can you plug 240v appliances into 220v socket?

Yes you plug a 240v appliance into 220v receptacle.


240v box outside for a hot tub you need a 110v receptacle Can you wire it off the 240v box?

Using a box that is hire voltage than what you need can cause a short, and even a fire. So using a 240V box, when all you need is a 110v receptacle, wouldn't be a good idea.


Can you wire a 12 2 wire to a 20A 240V circuit breaker to get a 240V for an electric heater?

Yes


Why would someone use two positive wires to complete a house 2 plug receptacle circuit?

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.


What size amp circuit breaker should be used for 240V 7000KW?

For a 7000watts or 7kw a 240V then it is 30 Amp


If you install a 30A 240V GFI breaker will this be ok or will the cycles the dryer has prematurely fail the breaker?

I suspect you mean GFIC breaker. The dryer will not cause the breaker to fail.


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. Also, an existing 120v receptacle has nothing to do with your 240v receptacle. For a 240 volt receptacle, you'll need to run 2 new 120v lines (in the same cable). The existing 120v circuit cannot be used here, even if you added another 120v circuit, because when a load uses 240v, both 120v circuits supplying the 240v must be controlled by a common disconnect (a 2 pole breaker designed for 240v circuit). My advice would be to show an electrician what you want done. I'm sure they can tell you how to make that happen.


Is it possible to convert a 120V receptacle on a power generator to a 240V receptacle?

You can using a transformer, but you won't have as many amps available. 5000 watt generator @ 120v = 41.66 amps 5000 watts / 240v = 20.83 amps

How do you wire a 15 amp breaker for 240v?

A single pole 15 amp breaker can only be setup for 120v. You need a double pole 15 amp breaker, which looks like two 15a breakers attached with a bar across the two actuators. Each leg provides 120v, or in the case of your breaker, 240v across the two legs.


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?

The voltage is correct, BUT, Your welder is going to draw more current than the pool pump did. The breaker, wiring, and the receptacle will have to be upgraded. In my opinion I have never seen a "temporary" connection!! ...pkazsr

How do you run dedicated 240V lines for power tools?

Answer for USA, Canada and countries running a 60 Hertz supply service.One 240 volt receptacle fed from a two pole breaker from the distribution panel. The size of the breaker is determined by the load current and the wire sized accordingly.


How can you install a 240V receptacle from the bare wires for an electric range?

Bare wires!?!?!?! For 240V you need 3 wires plus ground. Red and Black are hot, white is neutral. Don't mess with 240V if you have no idea what you're doing. It's not safe at all.


How many amps are on a double pole 30 amp circuit 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 30 A.
