A. Provide surge protection to both sides of the
recloser.

N
The horizontal bushing is the source side and the
vertical bushing is the load side. See Figure 16.
B. Connect high-voltage lines to recloser bushing
terminals. The recommended torque value for
bushing terminal-to-line connection is 45-50 ft•lbs.
Refer to Figure 16 for terminal identification of the
SPEAR single-phase recloser.
Terminal connection to only copper conductors is
recommended.
CAUTION
Equipment damage . Do not adjust or rotate bushing
terminals without first removing power line leads
and loosening pinch bolt to release clamp tension .
Failure to remove tension between the clamp and
the interrupter stud prior to rotating the terminal will
damage the encapsulated interrupter assembly resulting
in equipment damage .

CAUTION
Equipment damage may occur if torque values are
exceeded .

To rotate a flat-pad or eyebolt bushing terminal
prior to connecting power line leads, loosen the
pinch bolt on the terminals. After rotating the
terminal, retighten the pinch bolt as follows: torque
3/8-16 pinch bolts to 15–17 ft•lbs (20–23 Nm);
torque 1/2-13 pinch bolts to 29–31 ft•lbs (39–42
Nm).
