For Jacketed Feeder Cable Only:

For jacketed feeder cable, center mastic strip over cut-

back edge of cable jacket, so that it seals onto both the

cable jacket and insulation (Figure 4).

For Jacketed Feeder Cable Only:

If jacketed feeder cable is used, remove an additional

1/2" (13 mm) of jacket, leaving 1/2" (13 mm) of cable

insulation exposed (Figure 2).

A. Prepare Cables According to Standard

Procedures

1. Check to be sure cable sizes fit within the kit range as

shown in Table 1.

2. Remove cable insulation for length recommended

by terminal lug manufacturer; if no information is

available, remove for depth of lug barrel.

Note: If a split bolt connector is used, refer to Table 2

below for maximum split bolt size for each kit.

B. Install Lugs

1. Install and crimp lugs per manufacturer’s direction.

(See back page if 3M™Scotchlok™Copper Lugs are

used.)

2. Clean insulation (or jacket as applicable) for

approximately 6" (152 mm).

3. Bolt lugs together. See Table 1 for maximum bolt

length, and Figure 1 for proper bolt/lug arrangement.

C. Installation

Note: If moisture resistance is not required, proceed

to Step 4.

1. To gauge mastic build up in next step, temporarily

install lug cover over bolted lugs, leaving 1/2"

(13 mm) of lug exposed.

Note: Position lug cover so punched holes are

positioned between the two conductors (Figure 3).

2. Separate the cables and apply mastic strip around

insulation and between them at a position just onto

insulation (Figure 3). For jacketed feeder cable, see

note below. Build thickness so the overall diameter is

slightly larger than the observed inside diameter of the

lug cover. Press cables together and be sure that no

void exists between them.

3. Overwrap the mastic with 1 or 2 wraps of vinyl tape.

4. Install lug cover.

Note: The kit contains a small tube of silicone grease.

Use it to lightly lubricate the mastic-vinyl wrap.

This will aid in installng the lug cover (Figure 3

or 4, as applicable).

5. Be sure the locking pin (punched) holes are beyond

the cable end of the mastic-vinyl wrap. Insert plastic

locking pin through holes. HINT: Inserting pin from the

blind (back) side of lug cover will aid in visually seeing

the pinpoint for proper alignment through the second

hole (Figure 5).

6. Cut off excess pin length, if desired. Must leave 1/4”

(6 mm) extended out of cap.

2. Slide Lug Cover off of lugged or split-bolt connection.

3. If splice was sealed for moisture resistance: Remove

Mastic and Vinyl Tape Seal from cables.

4. Remove nut and bolt (or split-bolt) to separate the

motor lead from the feeder cable(s).

 Caution

Be careful not to damage cables.
