With electrical loads, the voltage will drop, hence the common reference to voltages below 1 and 240, such as 110, 115, 2, and 230 Moreover, whats the difference between 8v and 240v? The 1/8 volt 3 phase feed (8 volts hot to hot) does not have a high leg so the feed wires can be connected up top in any order The 1/240 volt 3 phase high leg feed wires have to be arranged in the correct order at the top of the panel in order that the 1 volt hot to neutral legs match up with the breaker slots down below 1/8 Y 240 delta on a normal 1/240 transformer you got 1 primary 2 secondary coils rated at 1V 3 bushings on the transformer 1 neutral 1 x1 to x2 is 1 x2 to x3 is 1 x1 to x3 is 240 1/8 i wish i could explain more on it thats all 3 phase volatage (i didn't do my 3 phase class yet)

Category science physics 49/5 (2,248 Views 21 Votes) "2" and "240" are the same thing "2" is what the unqualified use to describe 240 volt circuits 8 can only be obtained from a 3phase wye system 8 is from a 3 phase system and 240 can be from a single phase or a 3 phase system Click to see full answer 8/230v motors also have a harder time starting up, and they may produce a problematic voltage drop more often when connected to 8v Voltage drop usually isn't an issue for splitphase 240v systems However, on 8v, the motors start with a lower voltage Therefore, the same amount of drop will have a greater effect on the system 1/240 is single phase and 1/8 is 3 phase They coexist because single phase is most practical for residential and most small/medium commercial while 3phase is better for anything beyond that
As the power is derived from a 3Ø source, the power supplied is actually 1/8, as opposed to a traditional 1/240 volt Edison type feed It is common practice in many regions to identify 1/8Y conductors as BLACK, RED and BLUE Local regulations may amend the NEC Appliances and equipment rated for 1/240 volts may be used on a system that measures 110/2 volts Appliances and equipment rated for 1/8 volts but not 1/240 volts may generally not be used on a 1/240 volt system or on a system that measures 110/2 volts (Some analysis would need to be done to see if a particular item would work) tenant gets 8/1 single phase I don't know what 240 volt loads are in the units If you use gas for the cooking and laundry, the entire issue of 8 vs 240 in the tenant units goes away The only other load would be A/C, and those are normally dual rated for 230/8 volt
4 What about 3phase?8 volts is type of 4wire 3 phaseHere is an example of a 10W microwave in a 1V vs 240V circuit We have 10W appliance, Watts= Volts x Amps, so if we use a 1 v circuit we would be drawing 10 A (10/1) on the single hot conductor/circuit If it was a 240v circuit (2 conductors) it would be drawing 5 amps (10/240) per circuit for 5 total amps

Beside this, is 8 the same as 240? This creates a traditional 240 v/1 v panel where there are 2 legs of 1 v and from hot to hot you would measure 240 volts To supply a 8 v load, the transformer provides 1 v Hot Leg;3 What is 240 V?

Among these are 240 Delta, 1/240 3phase 4wire delta with a "wild" leg (HighLeg Conductor Identification, NEC ) and the above Sometimes you will hear the voltages reversed, such as 8/1 volt 3phase 4wire wye You will occasionally hear of voltages like 2phase and 4phase, but these are usually found on the East coast where3 Why 8 V? Assuming that the wire size running to these can accomadate the slightly higher current draw from 8V vs 240V (from either the 1/240Delta service or regular 1/240 single phase service) Just the same as with three phase 1/8V with a three phase motor rated at 2240V running on 8V three phase

1/8 3 phase is a more modern system called Wye It has 1V to ground on all 3 legs and 8 volts between any of them 1/240 3 phase is an older system called Delta It has 2 legs @ 1V to ground and one leg @ 8 V to ground with 240 between any of the hot legs I got a call from an electrician and building owner who had already started work to convert an existing 240/1 volt, threephase delta service to 1/8volt wye The power company wanted to get rid of the old transformers and service and provide a new pad mounted transformer for the building 1/8V is the standard 3 phase voltage 230 volt motors were run on 8 volts for years but it is becoming more common to use 0 volt rated motors on 8 volt systems 1/240V is the standard single phase system voltage 230 Volts, where to start 230 volts is a valid motor voltage

This is typically what you'll see in homes and small businesses 1 volts and 240 volts for a singlephase, and 1, 8, and 240 for threephase Depending on how a transformer is wound at the service, you'll have 8/1 or 240/1, and in the case of a 3phase 4wire Delta application, you'll have 8/240/1 all in the same serviceVoltage Differences 110V, 115V, 1V, 2V, 230V, 240V You'll often hear voltages in your home referred to as 110V, 115V, or 1V This can be confusing but the bottom line is they are referring to the exact same thing 1V is the AC voltage on a single hot wire in your home with respect to neutral (or ground)Voltage between High leg and Neutral = 1/2 x 2V x √3 = 8V (1Φ) Voltage between two hot Phase = 1V x 2 = 240V (1Φ) Voltage between three Phases = 240V (3Φ) These are the general setup and may vary and depend on the installation eg neutral wire may be needed for three phase 240V outlets etc

So if AB, BC and CA are all 240 volts, then AN and CN will both be 1 volts, but BN will be 8 volts Other types of threephase supplies are wye connections, ungrounded delta connections, or cornergrounded delta ("ghost" leg configuration) connections These connections do not supply split singlephase power, and do not have a high leg The wye common point connection makes this a neutral point three phase cycle has 1 moments in any second in time when a sine wave is crossing zero volts in the cycle of the sine wave each phase is at a point the voltage will not be 240 volts but 8 volts on a wye transformer basically there not at the same peaks or points in time so its less voltage between phases8 is usually 3 phase It's stepped down to 1 for the 1 common single phase products to work Single phase 8 is usually available too It's just never stepped down to a 1 3 phase panel No point 277 comes from a 480 three phase system 277 is usually reserved for lighting and has a separate panel 277 is single phase too

The main benefits of 1V power are quite limited 1V AC Power has a reduced chance of producing a terminal electrocution should one occur 2V/240V Power 2V power divides the singlephase electricity into two separate 110V conductors that share a common neutral wire or ground This allows for a more efficient transfer of power 8V 3 Phase Power 8V 3 Phase power has 3 electrical legs (phases) evenly spaced in a circle (360 degrees / 3 phases = 1 degrees) around a center (neutral) Each leg (phase) provides power (phase voltage) at a unique angle (phase angle) to the center (neutral) 8V 3 Phase power also goes by the names 8V 3 Phase 4 Wire and 8Y/1VThe 1 option on 1 V outlets will do better with voltage reductions than 8/240 appliances powered by 8 The same may be true for AC compressors The 1 ac circuit will only require one space in your service panel while the 8/240 will require two

The wrinkle with three phase power comes when you would like to power 240v devices (eg a well pump, stove, dryer) If the device's nameplate states that it can run at 8v (in addition to say 2v or 240v), you are fine Sometimes the nameplate will state 40v as acceptable voltage rangesWiring a 1volt circuit off of a 240volt circuit can be useful where there is primarily 240 volts available This could be the case at a water well or a workshop A 240volt circuit is comprised of two hot wires, a common neutral wire, and a ground wire There is no distinction on those IEC connectors for 1V vs 8V/240V So you have an outlet strip and servers happily running at 8V/240V Sometime later you add another device which is either 1V only or manually selectable 1V / 8V/240V Not remembering that your outlet strip is providing 8V/240V, you plug in the device Poof!
