Where are control transformers typically located?

Control transformers are specifically designed to supply control voltages to various components in control circuits, and they are typically located within the control circuit panel. This positioning allows for easy access to the control load devices, such as relays, contactors, and control panels, which depend on lower voltage from the transformer to operate safely and efficiently.

By situating the control transformer in the control circuit panel, it facilitates better organization of the electrical control system, minimizes wiring runs, and helps prevent voltage drops that could occur if the transformer were positioned elsewhere. Such an arrangement also enhances safety by keeping control-related equipment together, reducing the risk of accidental contact with high voltage connections found in other parts of the electrical system.

The option to place transformers in the service panel, main circuit, or load section does not align with their intended purpose, as these locations are more suited for distribution and power handling rather than control logic management.
