Cable Operating Mechanisms

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

  • Disconnect all power before working on equipment.
  • Maintain electrical clearances between the cable and live electrical parts.
  • Verify by measurement that all power is disconnected.
    Failure to follow these instructions will result in death or serious injury.

CAUTION
SPRING LOADED MOVING PARTS
Keep hands free of the mechanism during device operation.
Failure to follow these instructions can result in injury.

Installation

Refer to Figure 1 and Table 1 on page 1 when installing and adjusting the device; Figure 3 and Table 2 on page 5 for panel mounting; and Table 1 for torque values, unless  otherwise noted.
The minimum cable bend radius is 5 in.
(127 mm), for a diameter of 10 in. (254 mm). To prevent multiple bends in the cable, do not loop or tie the cable to the enclosure frame. Maintain electrical clearances  between the cable and live electrical parts.
NOTE: Do not mount the operating mechanism to the panel at this time. That procedure is described on page 3. However, ensure that the cable length is adequate to mount  both the operating mechanism and the handle in the proper locations.

  1. With the mechanism bail arm (B) in the On position, remove the bail arm by removing the four screws (C).

  2. Slide the liner (4) into the mechanism, aligning it with the mounting holes.

  3. With the circuit breaker toggle and the operating mechanism in the On position, slide the circuit breaker into the operating mechanism, aligning it with the four  mounting holes.
    NOTE: Visi-Trip™ Handles are not compatible with Equipment Operating Mechanisms. For VisiTrip handle replacement steps and torque, refer to the circuit breaker instruction bulletin, shipped with the circuit breaker.

  4. Secure the circuit breaker to the mechanism with the four insulated mounting screws (3).
    NOTE: For circuit breakers that include the electronic trip unit, adjust the trip unit dials before installing the mechanism bail arm.

  5. Loosen the adjustment plate on the bail arm assembly:
    a. Loosen the left screw (G).
    b. Remove the right screw (F) and washer.

  6. Position the bail arm assembly so that the circuit breaker toggle slips through the adjustment plate. Secure with the four screws (C) removed in Step 1. See Figure 1.

  7. With the circuit breaker toggle in the On position, push the adjustment plate up so that it contacts the circuit breaker toggle.

  8. Ensure that the bail arm rests firmly against the mechanical stop (E) when the circuit breaker toggle is in the full On position.

  9. Locate the appropriate mounting hole in the vertical sawtooth slot, then reinstall and tighten the screws (F and G) and washer removed or loosened in Step 5. Torque the two screws to 70 lb-in (8 N m).

Mounting the Mechanism to the Panel

Secure the operating mechanism assembly (1) to the circuit breaker mounting surface (N) with four screws (2).

Mounting the Handle

  1. Referring to Figure 1 on page 1, install the handle according to its instruction bulletin—but install the handle mechanism portion of the operating mechaninsm in place  of the stiffener bracket supplied with the handle kit.
  2. Place the operating handle in the On position, and connect the flange mechanism coupler (M) to the handle linkage with the two bolts (supplied).

Adjustment

  1. Place the handle in the On position.
    If the breaker does not come to the full On position:
    a. Loosen the cable nuts (J) and adjust the cable forward (K) until the breaker moves to the full On position, and the bail arm rests against the stop (E).
    b. Torque the nuts to 100–120 lb-in (11.3–13.6 N m).

  2. Trip the breaker by depressing the push-to-trip button (H) with a small tool.

  3. Reset the breaker by moving the operating handle to the Off position.
    When reset properly, the breaker turns on with an audible snap.

  4. If the breaker does not reset:
    a. Place the handle in the On position.
    b. Loosen the cable nuts (J) and adjust the cable rearward (L) slightly until the breaker resets.
    c. Repeat as necessary until the breaker turns on and resets properly, and the handle operates the circuit breaker in the On and Off positions.
    d. Torque the nuts to
    100–120 lb-in (11.3–13.6 N m).

NOTE: For circuit breakers with a trip unit adjust option, refer to page 2 and complete the installation.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
After installation, verify that the door cannot be opened with the operating handle and circuit breaker in the On position.
Failure to follow these instructions will result in death or serious injury.
