I-T-E Rear Connecting Studs

General Description

One complete rear stud assembly requires the following:

1 1-12 threaded stud 1 “T” connector

1 Molded stand-off insulator 2 Brass locknuts

1 Insulator bushing 1 5/16-18 X 1 in. mtg. bolt

1 Insulator (req’d for metallic 1 5/16 in. Belleville washer

mtg. panels only

Mounting Preparation (Figure 1)

A. Drilling locations are shown in Figure 1. The 5/6 in. wide

cutout between holes is required when mounting the

breaker with stud assemblies to a metallic panel.

Breaker Preparation (Figure 2)

A. Remove wire connectors from breaker if present.

B. Attach long and short studs (1), (2) to circuit breaker for

three pole devices, short studs (1) only for two pole

devices. Attach with the 5/,6-18 X 1 in. hex head bolt and

the 5/16 in. serrated cone lockwasher (4). Tighten finger

tight only.

C. Slide one stand-off insulator (5) onto each stud until the

stand-off insulator fully covers the square end of the

studs. Tighten hex head bolt (3) to 132 in. Ib. and install

insulator (10) over studs only if using a metallic mounting

panel.

Final Assembly (Figure 3)

A. Install circuit breaker so that all studs extend through

mounting panel and the stand-off insulators (5) are

seated against the mounting panel.

B. Install insulator bushings (6 and 7) over studs where

required and tighten them securely in place against the

mounting panel with the locknut (8).

C. Thread the second locknut (8) and the “T” connector (9)

over the studs as far as possible where required. Position “T”

connector as desired by loosening (one full turn max.) and

lock in place with the second locknut at 132 in. Ib.

Important User Note

Assemblies are designed with adequate 600 volt electrical

clearance between components. User installation must main-

tain these clearances through spacing or proper insulation.

A. Insert the upper end shields (11) into the slots provided

at the line and load ends of the breaker (Figure 2), one

for each stud position.

B. Affix the label Pc. No. 60229 to breaker cover (Figure 2).

C. Make desired bus bar connections with 5/16 in. bolts

and washers to “T” connectors. (See Figure 3 for hole

pattern of “T” connector).
