    Leviton's new Lev-Lok modular wiring system consists of two components: a wiring device and wiring module (locking connector with leads). This system saves time and money, while improving safety and performance.
    These receptacles ship in a clear polybag with a factory installed protective cover that keeps the contacts clean during rough-in. To test circuits peel-back the protective cover. After testing, identify the circuit with the circuit ID label.
    The Lev-Lok system offers accessories that include complementary plastic, nylon and metal wallplates in single to four-gang configurations in matching colors.

    INDUSTRIAL GRADE Receptacles from Leviton:
  • They are UL/Fed Spec W-C-596 CSA , NEMA WD-1 and 6 and NOM compliant
  • Constructed of impact-resistant thermoplastic nylon so the cover and the base remain securely fastened even in rough use applications and environments.
  • The large triple-wipe “T” contacts are made of high performance brass to produce great contact pressure that ensures outstanding conductivity and minimal heat rise.
  • The unique V-shaped and serrated back wiring clamps increase conductivity with 3-point contact.
  • The deep-cut, mill-slotted #8-32 high performance brass terminal screws with undercut annular binder-head design reduce the oxidation on the conductors and improve continuity and reliability of the device. (Screws for Canadian devices are straight slotted).
  • 8 deep-funnel back wiring holes guide the stripped conductors to the terminals for easy, fast installation, reducing labor costs. Accept #10-14 AWG solid or stranded wires.
  • Dual grounding connection option: The integral green grounding screw and Groundmatic® self-grounding clip riveted to the strap never loosens or falls off and provides automatic ground connection when correctly mounted to a grounded metal wallbox.

    HOSPITAL GRADE Receptacles from Leviton:
  • Displaying a green dot, they are UL/Fed Spec UL 498 file #E13399, CSA file# LR 406, and meet WD-1 & 6 standards.
  • Hospital grade receptacles (with the green dot) guarantee that your critical care equipment and electronics have the most reliable connection.
  • Hospital grade receptacles perform better than ordinary heavy-duty devices that would get destroyed during UL testing.
  • They were made specifically for applications that require superior performance and high abuse tolerance like repeated plug insertion and pulls without chipping the cover plate or any breakage.
  • The face’s smooth cover design means that dirt won’t collect and cleaning is easier and faster.
  • The face is securely fastened into the base with an exclusive 4-corner latch system for superior reliability.
  • The one-piece, 0.050” thick locked-in brass mounting strap with integral ground contacts provide excellent ground resistance.
  • The large triple-wipe “T” contacts are made of high performance brass to produce great contact pressure that ensures outstanding conductivity and minimal heat rise.
  • The unique V-shaped and serrated back wire clamp increases surface area contact and conductivity for both solid and stranded wires.
  • The deep-cut, mill-slotted #8-32 high performance brass terminal screws with undercut annular binder-head design reduce the oxidation on the conductors and improve continuity and reliability of the device. (Screws for Canadian devices are identical).
  • 8 deep-funnel back wiring holes guide the stripped conductors to the terminals for easy, fast installation, reducing labor costs. Accept #10-14 AWG solid or stranded wires.
  • Dual grounding connection option: The integral green grounding screw and Groundmatic® self-grounding clip riveted to the strap never loosens or falls off and provides automatic ground connection when correctly mounted to a  grounded metal wallbox.
  • Convenient break-off tabs allow easy 2-circuit conversion.
  • Apron barriers help prevent accidental terminal screw contact with the metal wall box.
