What connects the T1, T2, and T3 terminals on a contactor?

• A. Control circuit wires
• B. Ground wires
• C. Load wires
• D. Power supply wires

Answer: (C)

T1, T2, and T3 are the outputs of the contactor’s main contacts. They are where the wires going to the load (the motor or other device) attach. When the coil is energized, the internal contacts close and connect the incoming power from the line side to these T terminals, delivering power to the load. Ground wires are for safety and don’t pass through the main contacts, and control circuit wires feed the coil, not the load path. The line supply wires go to the line-side terminals, while the T terminals carry the load current out to the equipment. So the wires that go to the load are connected to T1, T2, and T3.
