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

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 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 versa 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

The 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; 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 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)
