SPEAR™ Single-Phase Recloser System

INSTALLATION AND OPERATION INSTRUCTIONS

   MN280048EN   June 2016

Grounding the control

The control cabinet must be grounded. A grounding 

connector on the underside of the cabinet will 

accommodate No. 14 solid through No. 4 stranded 

conductors.
Suggested methods for grounding the control and recloser 

are shown in Figure 19 and Figure 20.
Figure 19 illustrates grounding methods for 4-wire multi-

grounded systems with local supply voltage transformer.
Figure 20 illustrates grounding methods for 4-wire multi-

grounded systems with remote supply voltage transformer 

(within one-pole span).
For effective surge protection, all control and power 

conductors for the SPEAR single-phase recloser control 

must be routed parallel to a corresponding ground path. 

For example, the AC power supply for the control should 

be parallel to and equal in length to the transformer ground 

path. The control cable should be parallel to and routed 

close to the recloser ground path.

Grounding with a local supply voltage transformer; 

4-wire multi-grounded

Installation of a SPEAR single-phase recloser control with a 

local supply voltage transformer must include the following:

Protection of the recloser bushings and the supplying 

transformer with lightning arresters.

Grounding of the recloser head and tank.

Grounding of the transformer tank.

Grounding of the control cabinet.

Grounding of the SCADA equipment.

IMPORTANT

All external inputs to the SPEAR single-phase recloser 

control must be routed within 8 inches of their 

corresponding ground. During a surge, a potential of 

approximately 1.5 kV per foot can develop in the conductors. 

Differences between conductor and ground path lengths 

can add additional stress to the control components in the 

event of a power surge.

IMPORTANT

In pole-mounted applications, a ground connection must 

be made between the recloser, transformer, recloser 

control, and SCADA equipment for proper protection of the 

equipment. The pole ground must be sized per local utility 

practices to minimize the impedance between the recloser 

and the control.

multi-grounded with local supply voltage transformer

 WARNING

Hazardous voltage . Recloser and control must be 

solidly grounded . Follow all locally approved procedures 

and safety practices when grounding this equipment . 

Improper grounding can result in contact with high 

voltage, which will cause death or severe personal 

injury .
