When installing a NM connector, tighten it until

• A. It is snug
• B. It is tight
• C. It is secure
• D. It is flush

Answer: (A)

Tightening until it is snug ensures the cable is held securely without risking damage to the insulation. The connector’s job is to provide strain relief so the NM cable can’t be pulled out easily, while not crushing or nicking the outer jacket. When you reach snug, you’ve got enough grip to prevent movement but you’re not applying excessive pressure that could deform the jacket or conductors. If you go further than snug, you may damage the cable or its insulation. Saying it should be tight or secure is less precise, and flush isn’t about how tightly the grip is; it refers more to how the connector sits against the surface.
