are

best

handled

by

lugs

are

provided

on

of

the

switchgear

.

When

using

a

crane

for

lifting

,

a

cable

spreader

must

be

used

to

obtain

a

vertical

pull

on

the

lifting

lugs

.

Recom

-

mended

lifting

method

is

shown

in

Figure

.

CAUTION

:

IF

THE

SKID

HAS

BEEN

RE

-

MOVED

,

BE

SURE

THE

ROLLERS

USED

ARE

SPACED

SO

THAT

THE

THREE

CHAN

-

NELS

REST

ON

TOP

OF

THE

ROLLERS

,

A

DIRECT

APPLICATION

OF

THE

ROLLERS

BETWEEN

THE

CHANNELS

MAY

TEAR

OR

DISTORT

THE

EQUIPMENT

.

If

practical

,

the

shipping

skid

should

be

left

on

the

equipment

until

it

is

at

or

near

its

final

location

.

If

crane

facilities

are

not

available

,

the

equipment

may

be

moved

into

position

by

means

of

construction

rollers

placed

under

the

shipping

skid

,

Where

overhead

clearance

is

insufficient

,

the

shipping

skid

may

be

removed

and

the

equipment

moved

by

rollers

placed

under

the

three

channels

under

the

equipment

.

4

Jacks

may

also

be

used

,

are

much

the

same

as

for

indoor

equipments

except

that

lifting

plates

are

provided

at

the

base

of

the

structure

.

The

lifting

plates

should

be

removed

after

the

equipment

is

permanently

anchored

so

that

passageway

at

the

ends

of

the

equipment

will

not

be

obstructed

.

f

,

\

If

it

is

necessary

to

store

the

equipment

for

any

length

of

time

,

the

following

precautions

should

be

taken

to

pre

.

If

dampness

or

condensation

may

be

encountered

in

the

storage

location

,

heaters

must

be

placed

inside

the

units

to

prevent

moisture

damage

.

Approximately

250

watts

of

heat

in

each

unit

is

required

.

On

outdoor

switchgear

this

may

be

accomplished

by

making

a

temporary

power

supply

connection

to

the

heaters

Each

breaker

compartment

has

four

positions

.

They

are

illustrated

in

Figure

18

and

described

below

.

1

.

CONNECTED

POSITION

—

The

breaker

is

in

operating

position

,

both

primary

and

secondary

contacts

made

and

the

door

closed

.

2

.

TEST

POSITION

—

The

primary

contacts

are

separated

by

a

safe

distance

,

but

the

secondary

contacts

are

made

.

Any

breaker

test

not

involving

power

may

be

made

in

this

position

.

The

door

may

be

closed

in

this

posi

-

tion

,

and

must

be

closed

before

charging

the

spring

on

a

manually

operated

AKR

breaker

because

an

open

door

will

interfere

with

the

breaker

handle

travel

.

3

.

DISCONNECTED

POSITION

—

Neither

the

primary

nor

the

secondary

contacts

are

made

,

The

door

may

be

closed

.

4

.

WITHDRAWN

POSITION

—

The

breaker

is

completely

out

of

its

compartment

ready

for

removal

from

the

equipment

.

The

door

must

be

open

.

NOTE

;

ALTHOUGH

THE

IT

IS

CAUTION

;

NEVER

OPEN

These

breakers

are

supported

on

a

rollout

track

in

the

same

manner

as

the

AK

breakers

,

However

,

since

the

rackout

mechanism

is

mounted

on

the

breaker

,

there

are

no

jackshafts

in

the

enclosure

.

so

that

the

end

with

the

A

channel

is

provided

on

the

top

of

the

equipment

which

serves

as

the

track

for

the

single

wheel

on

the

rear

of

the

hoist

assembly

,

If

space

is

available

at

the

end

of
