lettering system used here is from a U.S. government document, which defines the letter names and gives a (not always correct) list of what plug types are used where. Although useful for quick reference, the document is ambiguous in some areas. A plug and socket that are classified here under the same letter will usually mate, but there is no guarantee of this. A more up-to-date and authoritative reference on plugs and sockets is IEC Technical Report 60083.
Voltage ranges
Distinction should be made between the voltage at the point of supply (nominal system voltage) and the voltage rating of the equipment (utilization voltage).

The lettering system used here is from a U.S. government document, which defines the letter names and gives a (not always correct) list of what plug types are used where.

Voltage ranges


Distinction should be made between the voltage at the point of supply (nominal system voltage) and the voltage rating of the equipment (utilization voltage). Typically the utilization voltage is 3 to 5% lower than the nominal system voltage; for example, a nominal 208 V supply system will be connected to motors with "200 V" on their nameplates. This allows for the voltage drop
Voltage drop

Voltage drop is the reduction in voltage in an electrical electrical network between the source and load. In electrical wiring national and local electrical codes may set guidelines for maximum voltage drop allowed in a circuit, to ensure reasonable efficiency of distribution and proper operation of electrical equipment ....
 between equipment and supply. Voltages in this article are the nominal supply voltages and equipment used on these systems will carry slightly lower nameplate voltages.
