With electrical loads, the voltage will drop, hence the common reference to voltages below 1 and 240, such as 110, 115, 2, and 230 Moreover, whats the difference between 8v and 240v? 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 1/8 Y 240 delta on a normal 1/240 transformer you got 1 primary 2 secondary coils rated at 1V 3 bushings on the transformer 1 neutral 1 x1 to x2 is 1 x2 to x3 is 1 x1 to x3 is 240 1/8 i wish i could explain more on it thats all 3 phase volatage (i didn't do my 3 phase class yet)
