Equipment Installation

Figure 4-4 Lifting plate location

NOTICE

If the equipment line-up was split into shipping

sections, the lifting plates on corners of adjacent

sections shown in Figure 4-4 must be removed.

Failure to remove these plates will interfere with

mating adjacent sections and prevent installation of

bus splice plates, structure tie plates, etc.

Arc Vault sections are equipped with lifting plates. These

plates can be left in place when the Arc Vault section is

positioned separate from the line up. Lifting plates must be

removed if section will be positioned directly next to the

switchgear line up.

Once the lifting plates have been removed, they may be

discarded.

NOTICE

If the lifting plates must be reassembled on the

equipment for lifting, they must be moved to

locations where unused screw holes are available,

generally by shifting the plate horizontally on the

mounting surface one bolt-hole from its previous

location. When remounting the lifting plates, torque

the mounting bolts to 7-9 ft-lbs.

NOTICE

All mating sections of the equipment line-up

(including transformer, if applicable) must be securely

fastened together prior to tightening anchor bolts

fastening the equipment to the mounting surface.

2. REMOVE THE SHIPPING SKIDS-The equipment is fastened

to the shipping skids with 3/8-3 lag screws through the

equipment anchoring holes. See Figure 4-6.

Equipment shipping sections up to 10 feet long will be

fastened to the skids with four lag screws, one in each

corner. The shipping skid and lag screws are expendable

material and may be disposed of at the purchaser's

discretion.

3. FASTEN SECTIONS TOGETHER-After placement of the

equipment and installing the anchor bolts loosely, the

various shipping sections must be rigidly fastened together.

Through-bolts fasten each section of the switchgear

equipment to the adjacent section. Figure 4-5 shows the

location of the through-bolts.
