In a 120/240 volt split-phase system, what is the voltage between the two hot conductors?

In a 120/240 volt split-phase system, the voltage between the two hot conductors is 240 volts. This type of system consists of two hot conductors that are 180 degrees out of phase with each other. Each hot conductor provides 120 volts relative to the neutral conductor, which is why individual appliances can be powered at 120 volts.

When measuring the voltage between the two hot conductors, you are effectively measuring the total voltage potential difference created by the two phases. Since these conductors are out of phase, the voltage measured across them is the sum of their individual potentials, resulting in 240 volts. Therefore, the correct answer is indeed 240 volts.

Other responses, such as 120 volts, would only apply when measuring the voltage across one hot conductor and neutral; 300 volts and 60 volts do not correspond to any standard measurements in this context. The understanding of the phase relationship in this type of system is crucial for recognizing how the voltages interact.
