These are basically all the same thing The same goes for 240 volt single phase power Growing up, this was commonly called 2 volt power, usually found in the laundry room"By a factor of 3," I mean by a factor of root 3 Regarding this, can you use 8 volts or 240 volts?

120/208 vs 120/240 volt
120/208 vs 120/240 volt- Actually, it's the other way around; 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

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 Meaning there not at peak voltage in there cycle moments in time the difference is the measured 8 volts between these phases A B / B C / C A 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 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
8V Single Phase and 8V 3 Phase power are easy to use, but hard to understand If you want a simple understanding but aren't electrically minded, start with a 8V three phase is obtained by taking two legs of threephase power In a 1/240 single phase system, the midpoint of the secondary side of the tranformer is tapped and grounded to create a neutral From the midpoint to any line readsBTU, 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
A 240 volt outlet, on the other hand, is larger, with room for three individual plugs or four plugs of varying size You may think that the safe route, then, is to simply go with 1 volt outlets throughout your home But as it turns out, both the 1 volt and 240 volt alternatives can be beneficial, depending on your needs (and appliances)Mains electricity (Commonwealth English), also known by the American English terms utility power, power grid, domestic power, and wall power, or in some parts of Canada as hydro, is a generalpurpose alternatingcurrent (AC) electric power supply It is the form of electrical power that is delivered to homes and businesses through the electric grid in many parts of the world"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
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 systemSo 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 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)
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 1/8V 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 is21 indicates 1/8 VAC, three phase, four wire, four pole 22 indicates 277/480 VAC, three phase, five wire, four pole 23 indicates 347/600 VAC, three phase, five wire, four pole x is the position occupied by L for locking devices If no tester is present device is nonlocking, straight blade *excludes Class II connections Table 1 NEMA
The driver in the photo above is from a LED bollard light and is marked INPUT VAC and 277VAC This means the driver will work on any voltage between 100 volts and 240 volts as well as 277 volts It would not work on voltage between 241 volts and 276 volts 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 below1V is derived from what's really a 240V feed In the US, electricity is delivered to residences as what's known as "240V splitphase" the transformer at the street outputs 240 V with a center tap The cen
Here 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 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 itemsFollow @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
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 phaseThe confusion comes from the evolution of how we describe voltage in the USA Home voltage can be referred to as 110 volt, 115 volt, or 1 volt; 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
The holes in a 240 volt outlet all tend to be rounded or oddly shaped Around the World Countries like America and Canada use 1 volt power, but most of the rest of the world runs on 2 to 240 volt power Stepup or stepdown transformers can be bought that change 1 volt power into 240 volt power and vice versaThe long answer is the following Single phase power that typically comes to a home has two hot legs of 1v each You can use either leg to power 1v devices or combine both hot legs to power a 240v appliance or motor (eg for a wellpump) This power is all 60Hz Three phase power has three hot legs, each of 1v 1/240 refers to the common voltage into a typical home There are two lines that are 1 volts each supplying power to two different legs in your breaker/fuse panel Most circuit breakers or fuses will connect to one of these to provide power to your lights, outlets, and small appliances using the 1 volts to a "neutral" which is usually the
The question asks about substitution This is the process of confirming the suitability of one product for another In this case it is about electricl compnents, and the suitabilty of a 2pole circuit breaker, to function in a 3phase panel So, IIn NA, the terms 2V, 230V, and 240V all refer to the same system voltage level However, 8V refers to a different system voltage level 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
first, thanks to everybody i came into this with a mistaken impression based on a lifetime in singlefamily homes with 1/240 service (at 180 degrees) my apartment indeed has 1/8 at 1 degrees (the service panel, etc look the same) i imagine 1/3 of the apartments are on AB, 1/3 on AC and 1/3 on BC as others have said, heating The medium answer is YES, BUT!1/240V Professional Portable Diesel Generator superstore Huge selection of 240V Portable Diesel Generators Buy 240 Volt Professional Portable Diesel Generator Direct and save

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 systemsEfficiency or energy savings of 240 Volt vs 1 Volt appliances & devices This article describes the difference between wiring an electrical motor, such as a well pump, to operate at 1 volts compared with 240 Volts and answers the common question of whether or not wiring an electrical device to operate at higher 240 Voltage level will save on the electrical bill by using less energy 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?
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 Sure Power (Watts) is the product of current (amps) times voltage (volts) Add the powers of your two loads, divide by the new voltage (10 A*1 V 12 A*1 V)/8 V = 2640 W/8 V = 127 AThis 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 service
