2. Split-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Split-phase_electric_power

   Portable transformers that transform single-phase 240 V to this 110 V split-phase system are a common piece of construction equipment. Generator sets used for construction sites are equipped to supply it directly. However, a large farm may be given a 230–0–230 (nominal) supply.

3. Mains electricity by country - Wikipedia

   en.wikipedia.org/wiki/Mains_electricity_by_country

   Voltages in this article are the nominal single-phase supply voltages, or split-phase supply voltages. Three-phase and industrial loads may have other voltages. All voltages are root mean square (RMS) voltage; the peak AC voltage is greater by a factor of 2 {\displaystyle {\sqrt {2}}} , and the peak-to-peak voltage greater by a factor of 2 2 ...

4. High-leg delta - Wikipedia

   en.wikipedia.org/wiki/High-leg_delta

   Current practice is to give separate services for single-phase and three-phase loads, e.g., 120 V split-phase (lighting etc.) and 240 V to 600 V three-phase (for large motors). However, many jurisdictions forbid more than one class for a premises' service, and the choice may come down to 120/240 V split-phase, 208 V single-phase or three-phase ...

5. Electric power distribution - Wikipedia

   en.wikipedia.org/wiki/Electric_power_distribution

   Most of the Americas use 60 Hz AC, the 120/240 volt split-phase system domestically and three phase for larger installations. North American transformers usually power homes at 240 volts, similar to Europe's 230 volts. It is the split-phase that allows use of 120 volts in the home. Japan's utility frequencies are 50 Hz and 60 Hz.

6. Solar inverter - Wikipedia

   en.wikipedia.org/wiki/Solar_inverter

   Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...

7. Mains electricity - Wikipedia

   As in the UK, 240 V is within the allowable limits and "240 volt" is a synonym for mains in Australian and British English. In the United States [ 12 ] [ 13 ] and Canada, [ 14 ] national standards specify that the nominal voltage at the source should be 120 V and allow a range of 114 V to 126 V ( RMS ) (−5% to +5%).
