There are basically two standards for AC input power supply worldwide That is 230V in some parts of the world and 110V in some other parts 2 1/8V is for a 110V system basically with 1V as L to N and 8V as L to L Similarly, for 277/480V, 277 is L to N and 480V is L to L (V L to L = V L to N)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 voltageThe 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, I

What does 120/240 single phase mean
What does 120/240 single phase mean-So with THAT in mind, 1V to neutral on all three phases results in the phasetophase voltage being the LN voltage times the sq root of 3;The 8V/240V SmartUPS RT is a single phase UPS with a 3 wire unbalanced output They require 2 hots and a ground on the input, and 2 hots and a ground on the output They do not use a neutral They require a stepdown transformer

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/1V8V 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 reads 1V, and from linetoline (the full voltage) reads 240VIt's the one you use to plug in anything from your vacuum cleaner to your phone charging cable A 240 volt outlet, on the other hand, is larger, with room for three individual plugs or four

Technically 1/240 is called single phase not two or double phase Now with 1/8 is where I get confused I know it as 3 phase BRB (Black, Red, Blue) but, with that being said some argue its single phase??As explained above, in a utilityconnected, 1 / 240 VAC Single Split Phase System, the 1 / 240 VAC power consists of two 1 VAC lines viz Hot L1 (Phase A, Red wire) and Hot L2 (Phase B, Black wire) that are 180 degrees out of phase with respect to the center tapped, grounded Neutral (White wire) – see Fig 1Is available instead of 8 V Virtually all equipment that operates from singlephase 8 V will also operate from 240 V All of the same advantages relative to 1 V apply Very few servers today require 3phase power There are many sites, which simply do not have 3phase power available Also, the 3phase voltage in the rest of the world is

Since 110 is commonly used in place of 1, we may end up mashing together a 240V threewire three phase service and 1/8 (or another option 1/240) three wire single phase service So, I think I think what you call 2 line is actually single phase 1/240 but, again, given that we use 110 in place of 1, it could be referred to asBy a factor of 3, I mean by a factor of root 3Follow @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

For example, on a 1/8 threephase system, which is common in North America, the phasetoneutral voltage is 1 volts and the phasetophase voltage is 8 volts Standard frequencies of single phase power systems are either 50 or 60 HzSource, 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 NEC1/240 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

8V is what you get from 240V power in a 3phase "Wye" system That lets you get 1V between any phase leg and neutral and 8V between any two phase legs The reason it is 8V and not 240V is due to the phase angle being 1 degrees instead of 180 degrees240V power is used in the US and parts of the world In the US 1 / 240V 1 Phase 3 Wire is the standard for homes and 240V 3 Phase Open Delta is the standard for small buildings with large loads In parts of the world 240V Single Phase 2 Wire is240V single phase is obtained by taking a single leg of threephase power 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

Singlephase is commonly divided in half at the distribution transformer on the secondary winding to create splitphase electric power for household appliances and lighting Applications In North America, individual residences and small commercial buildings with services up to about 100 kVA (417 amperes at 240 volts) will usually have threewire singlephase distribution, especially inHowever, many jurisdictions forbid more than one class for a premises' service, and the choice may come down to 1/240 splitphase, 8 singlephase or threephase (delta), 1/8 threephase (wye), or 277/480 threephase (wye) (or 347/600 threephase (wye) in Canada) See also Transformer;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 service
