How can you verify proper torque on electrical connectors?

• A. Use a torque wrench to manufacturer's specification; ensure proper clamp load and no overtightening.
• B. Tighten until the connector is snug by hand.
• C. Tighten until the clamp feels tight enough for your judgment.
• D. Use a plain screwdriver to secure the fastener.

Answer: (A)

When securing electrical connectors, applying the right amount of clamp force is essential. The goal is to achieve enough clamping to maintain a solid electrical contact, while avoiding damage to threads, insulation, or the connector itself. The best way to verify that is to use a torque wrench set to the manufacturer’s specified value. This ensures the exact torque is applied consistently every time, producing the correct clamp load regardless of hand strength, lubrication, or surface conditions. Relying on hand-tightness or how the clamp feels by judgment introduces too much variability. Friction, surface finish, and techniques vary from person to person, so “snug” or “tight enough” cannot guarantee the correct clamp load. A plain screwdriver cannot measure or control torque, so it fails to verify proper torque and is unsuitable for securing such fasteners. By following the manufacturer’s specification with a calibrated torque wrench, you maintain reliable electrical contact and mechanical integrity without risking damage from overtightening.
