Which option is NOT a listed lug type for the four lugs (PERR)?

• A. Pin lug
• B. Recessed lug
• C. Quick lug
• D. Rocker lug

Answer: (C)

In this context, lug types are defined by the mechanical way the conductor is seated and clamped. The PERR set includes established geometries like a pin lug, where a pin helps locate and secure the wire; a recessed lug, which hides the contact area inside a cavity for protection and insulation; and a rocker lug, which uses a lever or rocking action to clamp the conductor. Quick lug, however, isn’t a formal lug geometry in this classification. It suggests a fast-connect idea but doesn’t correspond to one of the defined lug styles in the PERR lineup, so it’s the one that isn’t listed.
