Which of the following are common field terminations for control cables?

• A. Solder lugs.
• B. Crimp connectors are also used.
• C. Terminal blocks and barrier strips.
• D. Solder on fuses.

Answer: (C)

Common field terminations for control cables are terminal blocks and barrier strips because they are designed for field wiring in control panels and give secure, easily accessible connections that can be inspected and maintained. Terminal blocks let you clamp each conductor firmly and keep circuits organized, while barrier strips provide isolated terminals that reduce the risk of cross-connections and shorts as you wire multiple circuits. Solder lugs are less common in field terminations due to the heat and skill required for soldering in the field, and vibrations or temperature changes can stress solder joints. Crimp connectors are used in some harnesses, but they aren’t the typical field termination method for control panels. Solder on fuses isn’t a valid way to terminate conductors—fuses are protective devices, not terminations.
