A) IEC
B) NEMA
C) magnetic
D) reversible

Terminal Blocks

Electrical connectors that facilitate the easy connection and organization of wires in a circuit.

Single-phase

Refers to an electrical power system that uses only one alternating current (AC) voltage phase, common in residential and light commercial applications.

Three-phase

A system of three electrical currents or waves that are offset in phase by one-third of their cycle, commonly used in power systems for efficient electricity distribution.

  • Understand the differences between NEMA and IEC motor standards, including their implications for motor construction, wiring, and operation.

Final Answer :
A
Explanation :
Terminal blocks are a common feature in IEC (International Electrotechnical Commission) motors, which are used globally. NEMA (National Electrical Manufacturers Association) motors are primarily used in North America and typically use pre-wired connections rather than terminal blocks. Magnetic and reversible are not types of motors but rather characteristics or features that can be found in various types of motors.
