The plate frequently contains the names of the machine and its manufacturer, so the rating plate is often called a name plate (hence the term "nameplate capacity" for a generator), although many devices carry separate nameplates and rating plates. [1]
IEC 60051 Direct acting indicating analogue electrical measuring instruments and their accessories; IEC 60052 Voltage measurement by means of standard air gaps; IEC 60055 Paper-insulated metal-sheathed cables for rated voltages up to 18/30 kV (with copper or aluminium conductors and excluding gas-pressure and oil-filled cables)
In the European Community the IE2 class is mandatory for all new motors since 16 June 2011. The IE3 class will be mandatory from 1 January 2015 (7.5–375 kW) and 1 January 2017 (0.75–375 kW). [2] From June 1, 2021, three-phase motors from 0.75 kW to 1000 kW must meet at least IE3 efficiency.
Premium efficiency, when used in reference to specific types of Electric Motors (with a rotating shaft), is a class of motor efficiency.. As part of a concerted effort worldwide to reduce energy consumption, CO 2 emissions and the impact of industrial operations on the environment, various regulatory authorities in many countries have introduced, or are planning, legislation to encourage the ...
The International Electrotechnical Commission (IEC; French: Commission électrotechnique internationale) is an international standards organization [3] [4] that prepares and publishes international standards for all electrical, electronic and related technologies – collectively known as "electrotechnology".
Typically, facilities require motor-driven devices, transformers and capacitors. If this is the case, then the load banks used for testing require reactive power compensation. The ideal solution is a combination of both resistive and reactive elements in one load bank package.

The different classes are defined by NEMA, [1] Underwriters Laboratories (UL), [2] and IEC standards. For complete electrically operated appliances, the "insulation system" is the overall design of electrical insulation of the energized components to ensure correct function of the device and protection of the user from electric shock .
