Which of the following statements is true regarding the use of push‑in stab terminals on device wiring devices?

• A. 12 AWG copper (solid)
• B. 14 AWG copper (solid)
• C. 16 AWG copper (solid)
• D. 18 AWG copper (solid)

Answer: (B)

Push-in stab terminals are designed to grip a solid conductor only within a specific size range. The wire must fit the opening and be within the terminal’s listed range so the spring clamp can bite securely and create a reliable, low-resistance connection. 14 AWG copper solid fits the typical range these terminals are designed to accept, providing a secure bite and a dependable connection for standard residential wiring. Larger conductors like 12 AWG can be too bulky for the clamp to hold properly, while smaller ones such as 16 or 18 AWG may be too loose to maintain a solid contact or may not meet the device’s listed requirements. So, the statement that 14 AWG copper solid is appropriate for push-in stab terminals reflects the standard practice.
