Which item secures large wire splices?

Which item secures large wire splices?

• A. Ground clamps
• B. Splice bolts/compression lugs
• C. Terminal block
• D. GFCI/breakers

Answer: (B)

Large wire splice security relies on a mechanical clamp that also preserves a solid electrical path. Splice bolts and compression lugs are designed to pinch two or more conductors together, creating a tight, low-resistance connection that stays secure under vibration and current flow. Ground clamps serve the grounding path, not the splice itself. A terminal block offers a termination point and interface for wiring, but it doesn’t inherently clamp and secure large conductors in a splice. Protective devices like GFCIs or breakers shield the circuit from faults or overloads and don’t secure splices.
