Installation of insulated
terminal boots

Step 1

As shown in Figure 1, open the “clam-shell”
shaped boot with the “hinge” area away from the
cable path. Flex and install the boot so that the
opening in the boot will surround the conductor
between the glass-polyester conductor support
and the cables. Orient the boot so that the
terminal adapter copper bar will be encased inside.

Parts provided

Each shipment shall contain one terminal boot per
phase for each circuit. Boots vary in size based on
the number of lugs/cables per terminal adapter.
The illustrations herein represent only one size,
but all items are installed in like manner.

Step 2

As shown in Figure 2, the openings for each cable must be cut into
the boot at installation. Using the raised areas as a guide, cut an
opening for the passage of each cable. Also, cut a slit between the
cable opening and the center flange, to permit insertion of the cable
into the boot. Unused raised areas (cable access points) will remain
as boots. Boots are designed for multiple cable options and for
universal fit whether cables are going up (as shown) or down.

Step 3

As shown in Figure 2, following encasing of the cables in the boot,
close the seam with plastic wire ties in each hole provided along the
perimeter of the boot. The exposed copper and terminal connections
should be effectively isolated inside the boot.
