I have to install a sub panel 1/240 single phase on to a 1/8 three phase system as per instructions of my boss What I would like to know is there a problem with running 240 equipment on a 8 system and why do we have these two nominal voltage systems Sent from my XT1565 using Tapatalk

"2" and "240" are the same thing "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 system Likewise, what is 8 volts used for?That distribution panel has a breaker inside which is a 3phase 480 volt 90 amp breaker which feeds down to a 75 kva 3phase 8V to 1V step down transformer That transformer then feeds to the 0 amp 3phase 1/8 panel board On top of that there are three existing panels 1/8VAC means that power distribution is 3 phase with neutral connection (Y System) 1V represents voltage of each phase to neutral point and 8V represents voltage between any two phases For balance systems, line to neutral voltage is line to line voltage divided by 173 (Sq root of 3) ie 1x173=8V and 277x173=480V

And is it because only two phases were used on a three phase service to feed the panel?As an example, let's use a 3 phase 8 volt line Each of the 3 lines will be carrying 1 volts If you look at the chart, you can easily see the power output of any 2 lines If one is at peak, the other line isn't at peak That's why in a 3 phase circuit it's incorrect to multiply 18 volts is type of 4wire 3 phase with 3

The medium answer is YES, BUT!Primary Voltage 480 Y 277 Secondary Voltage 8 Y 1 (Solar Transformer) This design features a fully rated neutral on both primary and secondary sides commonly required in solar applications The transformer can be fed with either 480 or 8 volts in a step up, or step down operation making it the perfect solutionYou can't get it directly, though there's a lot of equipment rated for 240V (usually specified at 230V) operation, that will still function at 8V, though it will produce 25% less power at that voltage If you actually want 240V, you'll need eith
