Line 1 to Line 2 is used to power 240 volt single phase loads such as a water heater, electric range, or air conditioner Three Phase Four Wire Wye 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"2" is what the unqualified use to describe 240 volt circuits8 can only be obtained from a 3phase wye system240 volts can be obtained from either a 1/240 residential system or a 240 volt 3phase delta system8 is from a 3 phase system and 240 can be from a single phase or a 3 phase system I have a 240 volt amp receptacle in 4x4 box There is a neutral wire not being used in the box Can I use (share) a 1 leg of the 240 with the neutral to a
What Is 8 Volts
What is the difference between 240 and 120 volt
What is the difference between 240 and 120 volt- 1/240V is a 240V single phase supply, center tapped to produce a "split phase" with 1V between either side to neutral, and 240V between the two hot lines 1/8V is two phases from a threephase supply There is 1V from Here is a clear and simple explanation of understanding the differences between 1v single phase, 240v Split Phase, and 8v 3phase from Academy Fellow KeinokuormaThere have been multiple threads discussing this electrical topic Because of increasing demand of this information, I will try to

Re 240 vs 8 Volt level II charging Tue 1042 pm I suppose if you added up the time it took to acquire and assemble something that would work (a 8 to 240 volt transformer), plus factor in the time you had to work to earn the money to buy such a device, you would be better off time wise just to wait a bit longer for your car to 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)Advantages of a 480/277 3 phase Volt system over a 1/240 2 Answers I have customer that needs to upgrade his service from 800Amps to 10Amps He currently has a 1/240V 3 phase system and a 1/240V System With 2 separate Meters
Actually, it's the other way around; For instance a 112 Volt, 500 VA transformer will boost the voltage 10% from 8V to 28V and has a low voltage current rating of 42 Amps A 124 Volt, 500 VA transformer will boost the voltage % to 250 Volts and has a low voltage current rating of 21 Amps The best would be a 118 Volt transformer (rated for boost applications) The medium answer is YES, BUT!
8V is *not* the same as 240V 8V is the voltage between phases of a 3phase "Y" circuit that is 1V from neutral to any hot Furthermore, is 8v the same as 2v? A 8 system is three phases of 1 volts to ground A 240 system with two legs of 1 volts Yes, it is allowable to connect a 1/240 service to a 1/8 sytem It must be marked as such Must be marked with Orange with black lettering stating the voltage Most utilities will do this with no problem Most RVs do not have any 240 volt items The standard 15A 1V circuit has capacity for 18kW * 80% = 144kW The standard 30A 8V circuit has capacity for 624kW * 80% = (about) 5kW That is a huge difference Also do remember that the 8V is more power efficient to the tune of 2% 1V is considered a lower density option but is readily available

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 phaseFollow @BlueSeaSystems AC Current flow in 1/240 V AC single phase three or four wire systems is frequently misunderstood This technical brief goes through a step by step process of adding one load at a time to a 1/240 V AC system and looking at the resulting current flows There is an assumed understanding of basic DC theory, Ohms Law (V Getting 8 volt single phase lighting and connecting it to two of the phase lines of a 1/8 volt system is no different than getting 240 volt lighting and connecting it up to the hot legs of a 1/240 volt system

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 legsSo 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"By a factor of 3," I mean by a factor of root 3

It is a Kenmore dryer model # and the plate says 1/240 volts I am getting a newer dryer from my sister and wanted to make sure that my electrical outlet can handle the new dryer I would like to know about my electric dryer It says on the plate 1/240 What does that mean?BTU, or British Thermal Unit, is a thermal heat measurement It takes one BTU to lower the temperature of 1 lb of water in one minute A 1volt air conditioner typically has between 5,000 and 14,000 BTU, while a 2volt air conditioner has 15,000 to 23,000 BTU The BTU you need depends on the size of the room you want to cool 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
