The proper use of the term refers to the timing difference between voltages in a multi-phase power system. This makes more sense if you know that one complete AC cycle is divided up into 360 degrees, the same as a circle is. At 0 deg. the voltage is zero. At 90 deg. the voltage hits the positive peak. At 180 deg. the voltage falls back to zero. At 270 degrees the voltage falls to the negative peak. At 360 (same as zero) degrees, the voltage rises back up to zero, then the whole process repeats. In a 3-phase power system, each of the three hot conductors carry a voltage that is offset 120 degrees, or 1/3 of a cycle, from the next conductor. The voltage on each wire peaks at a slightly different time. However, in everyday use, the term phase has also come to mean which one of the three wires you want, as in "connect phase A to terminal 6", etc. It is even used in 240 volt (US) household power systems, where there are two different hot wires, even though it is technically not a multi-phase power system. So, if an electrician says phase, he most likely means one of the three hot wires in a 3-phase system.

What are the specific electrical requirements for a 208/230 volt single phase appliance?
A 208/230 volt single phase appliance requires a dedicated electrical circuit with a voltage of 208 to 230 volts and a single phase power supply. The appliance should be connected to a properly rated outlet or wiring to ensure safe and efficient operation.
Is the type of wiring in most homes single-phase or three-phase?
Single phase.
What does multi-phase wiring mean?
Multi-phase wiring refers to an electrical system that uses multiple alternating current (AC) phases to distribute power. Typically, this involves three phases, known as three-phase wiring, which allows for more efficient transmission of electricity, reduced energy losses, and balanced loads across the system. This setup is commonly used in industrial and commercial applications to power large motors and heavy equipment. It also enables smaller wire sizes and improved overall system performance compared to single-phase wiring.
Are new houses in America using three phase wiring?
Three phase wiring is rarely used in homes in the United States. It becomes a fairly complicated process when most homes have a single phase wiring system.
