Which NEMA symbol represents a line-to-line connected load like a fan motor?

The NEMA symbol that represents a line-to-line connected load, such as a fan motor, is indeed associated with the correct choice. This symbol indicates that the load operates with a connection between two phases of the power supply.

In the case of a fan motor, it typically operates on a three-phase system, where it requires connection to two of the three phases (line-to-line) for its operation. The specific NEMA symbol reflects the operational requirements and connections necessary for equipment designed for this type of load.

The other choices represent different configurations or types of loads. For instance, some symbols might be related to single-phase connections or specific starting methods, which are not pertinent to a fan motor operating under the line-to-line condition. By identifying the correct symbol, one acknowledges the motor's requirements and ensures accurate wiring and installation practices in compliance with electrical standards. This understanding is crucial for safety and functionality in electrical installations.
