On a contactor, the terminals T1, T2, and T3 are typically connected to

• A. Ground wires
• B. Load wires
• C. Control circuit wires
• D. Neutral wires

Answer: (B)

A contactor’s main job is to switch the power that goes to the load, such as a motor or heater. The terminals labeled T1, T2, and T3 are the main power outputs that connect to the load wires. When the coil is energized, these terminals close the circuit between the incoming power and the load, letting the high-current current flow to the device. Ground wires attach to the frame for safety and aren’t part of the switched load path. Neutral wires may be present in the circuit, but they aren’t routed through these main load terminals in a typical contactor arrangement; the contactor’s function is to switch the hot/load side. The coil’s control wiring—not part of T1–T3—energizes the contactor to close the main contacts.
