What is the maximum number of terminal lugs that can be placed on a single terminal strip stud?

• A. three
• B. five
• C. six
• D. four

Answer: (D)

A terminal strip stud is sized to clamp only a limited number of lugs securely. Each lug needs clearance for its hole and for the nut to seat and torque properly, so the lug can grip the stud with the correct clamping force. Four lugs around a single stud provides enough contact area for reliable connections while leaving room for the nut and avoiding crowding or uneven pressure. Adding more than four would crowd the lug holes, reduce clamp force per lug, and risk a loose connection or overstressing the stud due to vibration. If more connections are needed, use a larger stud or a distribution block to maintain proper, secure connections.
