Fig.  14-Guicling  Circuit Breaker  into  Housing 

2. 

With the use of  the drawout handle,  back the 

breaker  into  the  housing  so  that  the  guide  bar  on 

the  breaker  enters  the  guide  slot  in  the  housing. 

Push breaker toward rear until breaker reaches the 

floor  stop  which  latches  it  in  the  "TEST"  position. 

If 

it  is  desired  to  test  the  breaker  for  operation 

electrically  and  manually  before  putting  it  into 

service,  it  may  be  done  in  this  position  by  means 

o

� 

the  push  button  on  the  front  of  the  breaker, 

F1g.  13  and  by  means  of  the  maintenance  handle 

as shown  in Fig. 

15. 

3. 

Seat  the  levering  device  pin  into  the  notch 

at  the  front  of  the  floor  guide  and  connect  the 

link  to  the  bracket  on  the  circuit  breaker  as  in 

Fig. 

16 

with the  breaker  in  the  "OPEN"  position, 

move  the  release  lever  toward  the  guide  slot  with 

the  right  foot  and  operate  the  levering  device 

through  one  stroke  until  the  breaker  engages  the 

stop  in  the  housing.  Turn  locking  device  to 

"LOCK"  position. Breaker is now in the "RACKED­

OUT"  position.  Discohnect  the  levering  device 

from  the  breaker.  Rack  in  by  inserting  the  crank 

and  turning  clockwise,  Fig.  17,  until  pointer  on 

breaker  panel  indicates  the  breaker  is  in  the  con­

nected "OPERATING"  position,  Fig.

While  in Test Position 

2. 

Open  door,  insert  crank  and  rack  breaker, 

Fig. 

17, 

to  "RACKED-OUT"  position  as  indicated 

by  pointer  on  breaker  nameplate. 

If  it is  desired to remove the breaker  completely 

from  the  housing,  continue  as  follows: 

a.  Move  locking  device  to  "UNLOCK"  posi­

tion  as  shown  in Fig.  13. 

b.  Seat the levering device pin into the notch 

at  the  front  of  the  floor  guide  and  connect  the  link 

to  the  bracket  on  the  circuit breaker as  in Fig. 

16. 

Operate  the  levering  device  through  onE  ;troke 

forward  until  the  floor  stop  latches  the  breaker  in 
the  "TEST"  position. 

c.  Remove  the  levering  device  and  apply 

drawout  handle  to  front  wheels.  Move  the  release 

lever  toward  the  guide  slot  with  the  right  foot  and 

draw  the  breaker  from  the  housing  as  shown  in 

Fig.

5HV -350  CIRCUIT  BREAKER  . 

This  circuit  breaker  has.  "TEST"  and  "OPER­

ATING"  positions  which  correspond 

to 

those  of 

the  other 

5HV 

breakers,  but  since it is constructed 

differently,  it  is  moved  from  one  to  the  other  by 

different  means.  For  details  of  the  construction  of 
the  breaker,  see  the 

SHV-350 

Circuit  Breaker 

Instruction  Book  listed  in  the  Bibliography  at  the 

end of these  instructions.
