Installation procedure

When untanking the recloser for inspection prior to 

installation, remove the four bolts that secure the tank 

and head casting. Trip the recloser and carefully lift the 

mechanism out of the tank.
1. 

Check oil level .

 Before installing the recloser, check for 

proper oil level. With the mechanism removed from the 

tank, the oil level should be up to the fill line marked on 

the tank liner.

2. 

Test oil dielectric strength .

 If the recloser has 

been stored for some time or is being relocated, 

perform a dielectric test on the oil in accordance with 

ASTM-  approved testing procedures.

A.  On new equipment, the oil must have a minimum 

dielectric strength of 26 kV.

B.  If the dielectric strength of the oil is less than 26 

kV, filter the oil to restore its dielectric strength to 

an acceptable minimum level.

3. 

Replace head casting and mechanism in tank .

A.  Wipe clean the O-ring type gasket, the gasket 

recess in the recloser head, and the tank gasket.

B.  Position and tighten the four head bolts alternately. 

The cover can be rotated to accommodate 

installation. Torque each head bolt to 11-16 ft-lbs.

C.  Operate the unit manually eight times to ensure 

that no air remains in the hydraulic mechanism.

4. 

Test mechanical operation .

 An effective test can be 

performed as follows:
A.  Move the yellow manual operating handle to the 

CLOSED position and wait at least 4 minutes.

B.  Move the manual operating handle to the OPEN 

position and listen for opening of the main 

contacts. (A dull “clunk” will be audible.) Then 

quickly move the lever back to the CLOSED 

position.(A metallic “click” can be heard.)

C.  Continue opening and closing the recloser manually 

until lock-out is achieved. This can be determined by 

listening for unlatching of the lock-out mechanism 

and also by noting that the recloser mechanism 

will not latch when the operating handle is moved 

to the CLOSED position. This test can be used to 

determine the number of operations to lock-out. 

The number of fast and delayed operations can 

also be identified. With fast operations, the main 

contacts will open almost instantaneously when the 

operating handle is moved to the OPEN position, 

while, with delayed operations, a short time elapses 

between opening of contacts and placement of the 

operating handle in the OPEN position. 

5. 

Check data plates .

 Make sure the ratings and 

settings on the recloser data plates are correct for the 

planned installation.

6. 

Mount the recloser .

7. 

Ground the recloser .

 Make the ground connection to 

the recloser ground connector (located 4” from the 

bottom of the tank).

Line installation

Provide the recloser with bypass switches and surge 

protection as shown in Figure 8. Surge protection on both 

sides of the recloser is advisable. If surge protection is 

provided on only one side,though, it should be located on 

the 

source side for line installations 

and on the 

load side 

for substation installations .

Connect the primary leads to the recloser. The source-side 

bushing is located above the sleet hood. To facilitate 

connection, rotate the cover of the recloser in 90-degree 

increments, as required. The universal clamp-type terminals 

accept No. 6 through 350-mcm conductors (No. 8 through 

2/0 for Type H reclosers).

 WARNING 

This equipment is not intended to protect human 

life . Follow all locally approved procedures and safety 

practices when installing or operating this equipment . 

Failure to comply can result in death, severe personal 

injury and equipment damage . 

G102 .1

 CAUTION 

This equipment relies on dielectric fluid to provide 

electrical insulation between components . The dielectric 

strength of the fluid must be checked on a regular basis, 

as part of the routine maintenance inspection, to ensure 

that it is at or above minimum dielectric requirements . 

Use of this equipment with dielectric fluid that does 

not meet minimum requirements can result in internal 

flashovers that will damage the equipment and can 

cause personal injury . 

G107 .3

 CAUTION 

Falling equipment . Use the lifting lugs provided and 

follow all locally approved safety practices when lifting 

and mounting the equipment . Lift the unit smoothly 

and do not allow the unit to shift . Improper lifting 

can result in severe personal injury, death, and/or 

equipment damage .

 G106 .3

 WARNING 

Hazardous voltage . Solidly ground all equipment . Failure 

to comply can result in death, severe personal injury, 

and equipment damage .
