Which statement describes the required method to connect wires to screw terminals?

• A. Must be twisted and taped
• B. Must be soldered directly to the terminal
• C. Must be a crimp or solder type spade lug
• D. Must use a lever lock terminal

Answer: (C)

When wiring into screw terminals, use a properly terminated end so the screw clamp has a solid, correctly sized contact. The best way is to fit a crimp or solder type spade lug to the conductor. This creates a clean, flat surface that fits under the terminal screw, resists fraying, and stays secure when tightened. Soldering directly to the terminal can overheat or damage insulation and makes future removal difficult. Twisting wires and taping them is unreliable and not up to code, and a lever lock terminal is a different style not suitable for standard screw terminals. So a crimp or solder lug is the proper termination.
