What does the 1 stand for in 115/60/1?
Answer:
Means that the power is single phase.
115 volts, 60 hertz, single phase
single phase
In electrical engineering, single-phase electric power refers to the distribution of electric power using a system in which all the voltages of the supply vary in unison. Single-phase distribution is used when loads are mostly lighting and heating, with few large electric motors.
The generation of AC electric power is commonly three phase, in which the waveforms of three supply conductors are offset from one another by 120°. Standard frequencies of single-phase power systems are either 50 or 60 Hz
