Installation

DANGER
When grounding inserts, minimize the length of the ground wire. Use of a longer
ground wire can result in a flashover to energized parts inside the component
compartment and serious personal injury or death when the TransFuser
Mounting is rotated to the closed position.
Verify that cables in termination compartments for fuses are correctly positioned
between the cable guides. Then terminate the cables with the elbows, following the elbow
manufacturer’s instructions.
NOTICE
Do not allow solvents used to clean cables prior to termination to contact the viewing
windows. The solvent can permanently etch the polycarbonate material.
The 600-ampere bushings supplied in S&C Manual PME Pad-Mounted Gear are
equipped with a stud as standard. Bushings are available without studs (Catalog Number
Suffix “-M1”) to accommodate 600-ampere elbows that do not require a stud. See Figure 9
on page 12.
Step 4
Connect the cable concentric-neutral ground wires to the ground bails and rods
provided, making sure that cables have sufficient mobility to allow the elbows to be moved
from bushings to parking stands. Connect the ground pads inside the pad-mounted gear
enclosure to the system ground facility in accordance with the user’s standard grounding
practice. Use the equivalent of 4/0 copper cable (or cable sized in accordance with the
user’s standard practice) in either a single or multiple connection to realize the maximum
momentary rating of the gear. For a multiple connection, cables smaller than 1/0 copper or
equivalent should not be used. Note: Concentric-neutral ground wires must be positioned
so that they will not interfere with TransFuser Mounting operation when the elbows
are on the parking stands.
Fault Indicators
Step 5
Optional mounting provisions for fault indicators (Catalog Number Suffix “-F1”
or “-F2”) are available. Fault indica tors are to be furnished by the user and installed in
accor dance with the manufacturer’s instructions. If mounting provisions are specified,
mount the fault indicators on the mounting brackets and attach the associated sensors
to the cables below the cable terminators.
