ALL ADAPTORS ARE SUITABLE FOR LINE OR LOAD END USE.
GENERAL A complete plug-in installation requires an adaptor for both the line and load end of the cicuit breaker, associated hardware and one switchboard mounting plate. The switchboard mounting plate is optional and can be replaced by other mounting means to suit requirements.
1. Turn off and lock out all power supplying this device before installing or servicing. 2. If the switchboard mounting pan (1) is to be used, provide required drilling as shown in Fig. 1. 3. If other mounting means are to be used, provide the cutouts and drilling required to mount the adaptor blocks as shown in Fig. 2.
SWITCHBOARD MOUNTING PLATE (If Used): Fig. 3 4. Place switchboard mounting pan (1) in position at location previously prepared in Step 2 above. Secure in place with 5/16”[M8] hardware (hardware furnished by customer).
MOUNTING BLOCK: Fig. 3 5. Align adaptor assembly (2) with cutouts in switchboard mounting plate (or customer’s mounting means as previously prepared in Step 3 above) and secure in place with 3/8 flatwashers (3), lockwashers (4), and 3/8-16 hex nuts (5) furnished. Tighten to 216 In.-Lbs.(18 Ft.-Lbs.)[24.40 N/m].

Installation Instructions BREAKER PREPARATION: Fig. 4 CAUTION: Make certain that breaker operating handle is in the OFF or TRIPPED position before proceeding. 6. Loosen four breaker terminal shields screws (6) and remove both line and load side terminal shields (7). 7. Place terminal stabs (8) on back of breaker in recess provided in base molding. Secure in place with 5/16-18 hex head bolts (11)
furnished. Tighten these bolts to 96 In.-Lbs. (8 Ft.-Lbs.)[10.84 N/m] to assure a good electrical connection. Repeat this procedure for the remaining terminals. 8. INSERT END SHIELDS (12) INTO SLOTS PROVIDED AT LINE AND LOAD END OF BREAKER. 9. Affix label (13) to front of circuit breaker as shown in Fig. 4.

Installation Instructions FINAL ASSEMBLY : Fig. 5 10. Make bus connection to mounting block studs in accordance with panelboard specifications. 11. Position breaker over the terminal blocks studs (14). Install each of the four slotted 3/ 8-16 X 1 1/4 In. long circuit breaker mounting nuts (15 ). Tighten these nuts uniformly so that the breaker remains parallel with the mounting surface, forcinf the circuit breaker terminal stabs into their repective mounting block finger clusters. Torque these nuts to 216 In.-Lbs.[24.40 N/m].
