Note
"2-phase" to describe US residential service is depricated nomenclature. US residential service is single phase because the two hot supply phases have 0 degrees of separation between their phases: therefore they are in phase.

The two phases are pulled from 2 out of 3 corners on a 240v (line-to-line) 3-phase delta-primary transformer, usually out in the street. (Sometimes at your house if it's a big one). Basically all power is generated and transmitted as 3-phase. Usually around 415V 3-phase comes into the primary of the 3-phase transformer. (It could be delta- or wye-connected.) The secondary windings for all three phases will each have a center-tapped connection, and that's grounded at the panel. This is the neutral wire. All circuits in houses return via the "common" or "neutral" wire to this point, which happens to be grounded at the panel. Note: no neutral wires should be grounded anywhere else. The two "corners" are 240v relative to each other, and 120v each to the center tap. Each 240V circuit really is two hot wires plus a neutral, which is why it's often wrongly called two-phase when in fact it's just single-phase. For each 120V circuit in the house you're going to use one hot wire and one neutral wire. The neutral wire provides a return path for currents back to the generating station. In some installations, such as apartment blocks, the third leg of power would be at 208V with respect to the center tap.

Just what does "220v single-phase split ac in the US which has a 110v 2-phase system" mean?

The vast majority of electricity in the US is delivered as single phase or three phase. The only areas in the US that use 2-phase [for industrial and commercial purposes] are Philadelphia/South Jersey [where it is being phased out-no joke intended] and somewhere out west...

It was one of the early poly-phase options pursued because of the natural magnetic differential between phases [makes motors spin without a capacitor]

Most residences receive 220-240 volt single phase electricity with a grounded center-tapped neutral, the purpose being to limit voltage to ground to less than 150 volts from either "hot".

# Why does the US run at 120V when some of the world runs at 240V?

Technology, current at the time of US electrification, locked theUS into 110, then 120 volt outlets . Europe'selectrification came later, and proceeded in response to advancedtechnology. The US was too deep into the 110/120 voltinfrastructure to upgrade. The US has remained in this situationever si (MORE)

# Why does a 120V-240V dual voltage single phase table saw motor produce 4 times more torque at 240V than at 120V?

Answer . I believe it has to do with the windings in the motor. When wired to 120V, half the motor has a positive polarity and the other half has a negative polarity. Then as the current alternates (60 hertz AC) the polarity flips, the magnetic poles oppose each other and cause the motor to spin. (MORE)

# Can an American 240V dual phase dryer be converted to work in Korea with 240V single phase power?

you could possibly design a fix for it but it would be a lot of trouble. the American dryer has internal components that run off 110v and that 110v is available from the three wire 220v circuit in the typical usa residence. this is because of the third wire, the neutral. the Korean 220 would be 2 wi (MORE)

# How do you change over so you can plug a 120V RV plug into a 240V single-phase twist-lock receptacle?

Answer . Is the 220V plug 220V only or 110/220V? (The former will have 3 prongs and the former will have 4)\n. \nIf your case is the latter just use the ground, neutral, and one of the hots. This will give you 120V single phase.\n. \nIf the case is the former you can't get 110V off that plug. (MORE)

# In the event of a city power cut can you use a single-phase 240V generator to connect across the two 120V phases supplying the house and would you still get 120V to neutral on each side?

Answer Yes you can BUT because you asked this question you should have a pro show you how to do it. Just to give you a worst case example, transformers work in both directions so if you feed the "city" with 220v your neighbors will enjoy your power until your generator burns up. Maybe 2-3 seconds!

# How do you convert a 120V receptacle to a 240V receptacle for an air conditioner that uses 240V?

Answer . \nA "110" volt outlet cannot be converted to a "230" volt outlet. A 230 volt outlet requires a new wire run to the outlet rated for the appliance you plan on plugging into it. Example an airconditioner that requires a 220 volt 20 amp circuit would have to have a 12/3 w/ground wire run t (MORE)

# How can you convert US 120V or 240V circuit into a single-phase 240V circuit to use on a European appliance?

The voltage isn't a problem, you can run 220 from your house and use that to run a European appliance, the problem is whether the appliance is dependant on line HZ. European is 50HZ and US is 60HZ. If the appliance specifies 220/50HZ, it will probably give you trouble here. If it says 220V/50 or 60H (MORE)

# Can you split a 240V wire to wire a 120V outlet?

Only half of the breaker will try to trip and the other half will not know to do the same therefore (MORE)

# Can a 240V thermostat be operated using 120V to the themostat and them wired to a 120V heating element?

Answer . a 240 volt thermostat (or any 240 volt switch) is generally a 2-pole switch which means it breaks both wires going to the load. You can use it for 120 volt loads by using one of the two poles for the "hotleg" wire and just splice through the neutral wire. this is a 2-pole switch (the (MORE)

# Can you use a 120v switch for a 240v application?

# Can you take single phase of 120V with a hot wire and a neutral step up to 480v and then step down to 2 phases of 120V or do you have to input 2 phases of 120v to get 240V out?

Theoretically that can be done with transformers, but the poweravailable would still be limited by the circuit breaker on theoriginal 120 v supply.

# How can you get a 240V 3-phase from 240V single-phase?

# How can a 240V single phase split ac work in the US which has a 120V 2 phase system?

The US does not use a two-phase system. In fact, two-phase systems are very rare, these days.

# How do you Convert 240V single phase to 240V and 120V single phases split ac system for testing purpose basically Indian system to US system?

It can't be done because the 240 v supply has a live and neutral. Asplit-phase 120/240 has a centre-tapped neutral so both outer wiresare live at 120 v. It can only be done with a 240/240 v transformer with acentre-tapped secondary.
