Multiple Choice

Which of the following conductors can be connected to a lug that is listed for CU only?

Explanation:
Lug listings specify which conductors can be terminated there. A lug labeled CU only is designed for copper conductors, matching the material, contact geometry, and torque requirements of copper terminations. Using aluminum, steel, or brass would violate the listing and can cause problems like poor contact, corrosion, loosening, or overheating because those metals behave differently with the lug’s clamping and plating. Aluminum, in particular, needs lugs rated for AL or Cu/AL to ensure a reliable connection. The safest, compliant conductor for a CU‑only lug is copper.

    Good for basics but I was hoping for deeper explanations on tougher circuits. The flash cards are helpful, and the MCQ style is realistic, but a few questions felt short on context. Still, it’s a useful tool when paired with hands-on work.
