Threephase electric power is a common method of alternating current electric power generation, transmission, and distribution It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power It is also used to power large motors and other heavy loads A threewire threephase circuit is usually more economical than an equivalent twoIn a singlephase AC power system there is only one single sinusoidal voltage Most AC power is produced and distributed as threephase power with three sinusoidal voltages 1 degrees out of phase with each other The diagram and table below can be used to convert amperage between single phase and three phase equipment and vice versaYes, your product would work on single phase 1 on a 1/8 V system The customer probably has 1 single phase, 8 single phase and 8 three phase, but may not Sometimes, some commercial establishments like apartments would be furnished 3 phase power to the building, but metered single phase to each apartment

120/208 single phase transformer
120/208 single phase transformer- In 1V and 8V, 1Phase & 3Phase wiring systems, the available voltage levels are as follows inside the main breaker panel Voltage between three hot wires (hot 1, hot 2 & hot 3) = 8V Three Phase Voltage between any two hot wires = 8V Single Phase Voltage between any hot wire and Neutral = 1V Single Phase 1/8V Single Phase Power 1/8V single phase is derived from 8V three phase power If viewed on an oscilloscope, the three voltage waveforms on the three "hot" conductors all peak at different times each one is 1 degrees behind the next When using 1/8V single phase, you will use any two of those same three hot conductors

1/8 to 240V AC Thermoplastic Centrifugal Pump, 1Phase, 2 in NPT Inlet Size Next 1/8, this can only be supplied by a 3 phase transfomer, it has 3 windings 1V each all connected together at one end (neutral), the voltage phase to phase is 1 X 173 (square root of 3) or you guesed it 8, 1/8 is normally used for A large apartment building would have a 1 / 8 volt , 3phase , 4wire service with three Ungrounded Phase Conductors ,Black / Red / Blue ,and a Grounded White conductor , the Neutral, Each apartment would be supplied with a 1 / 8 volt , singlephase , 3 wire "Feeder" consisting of two UnGrounded conductors and a Grounded "Neutral
phase to phase voltage is found by taking the single phase voltage and multiplying it by 173 1V phase A1v Phase B= 1 X 173= 76 If you really want to know where 173 came from I can find it, I really just remembered the "magic" number EDIT this would obviously be for a wye connection R 1 8v Single Phase Wiring Diagram – wiring diagram is a simplified okay pictorial representation of an electrical circuit It shows the components of the circuit as simplified shapes, and the skill and signal associates amongst the devices A wiring diagram usually gives opinion practically the relative point of view and arrangement of Typical commercial building power in the US is 1/8 volts, 3 PHASE as provided by the primary generation system and transformed down to usable voltages 240v is known as single phase, 3 wire, with 2 hots and a neutral and is common in
North America Phase Converter Co offers a full line of electrical single and three phase transformers Listed below are the most common voltage combinations If you don't see the step up or step down transformer that meets your power requirements, please call us and speak to one of our application engineers Let us see if we have what you need Each designation refers to a 3phase, 4wire source of power They are used to supply power to both 3phase and singlephase loads In other words in addtion to the 3phase wires carrying current, the neutral wire can too For example, in the USA, the first is properly designated as 8Y/1Electrostatic shield standard on all three phase units and single phase units from 750VA and up

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/1V The medium answer is YES, BUT!The most common commercial building electric service in North America is 1/8 volt wye, which is used to power 1 volt plug loads, lighting, and smaller HVAC systems In larger facilities the voltage is 277/480 volt and used to power single phase 277 volt lighting and larger HVAC loads In western Canada 347/600V is common

Dusty it's not unusual to have a single phase panel in a restaurant that has 3 phase power Yes you would only need 2 of the phases to create a single phase panel Reply to 1/8 on single phase panel in the American Professional Electrical Advice Forum area at ElectriciansForumsnet Forums CountrySpecific Electrical Advice 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 Ask someone else how this works laughing I'm just a mechanicSeries 1000 Single Phase Indoor Meter Kit, 1/240Volt 0 Amp 1P3Watt with 2 Split Core CTs, Gray Series 00 Three Phase Indoor Meter Kit, 1/8
