Single-Pole Bullet Breakers
Connect load cables to distribution panel bus bars. The top bus bar has a brown label marked
"Return Bus". Bus Landings are ¼" studs on 5/8" centers. 901352617 1/4-20 nuts are provided.
Torque to 65 in-lbs. Secure the Return Load Cable, then the Load Cable.
Cable size is 2 gage or less.
Verify wiring polarity at the input of the load equipment.
Insert single-pole breaker into the distribution as shown on the left side of the picture above. Verify
that the alarm pin is straight before insertion.
Ensure Circuit Breakers are in the OFF position prior to installation. 1-pole breakers rated 80A and
90A must have an unused position to one side.
Leave breaker switch in the OFF position until the load equipment is ready to be energized.
Single-Pole Bullet TPS Fuse Holders
Connect load cables to distribution panel bus bars. The top bus bar has a brown label marked
"Return Bus". Bus Landings are ¼" studs on 5/8" centers. 901352617 1/4-20 nuts are provided.
Torque to 65 in-lbs using 7/16" socket. Secure the Return Load Cable, then the Load Cable. Cable
size is 2 AWG or less.
Verify wiring polarity at the input of the load equipment.
Insert single-pole TPS fuseholder into the distribution as shown on the left side of the picture above.
Verify that the alarm pin is straight before insertion.
Ensure no TPS fuse or GMT Alarm Fuse is installed in the Fuse Holder Head.
Do not install load fuse and alarm fuse until the load equipment is ready to be energized.
Two-Pole Bullet Breakers
Two-pole breakers require a cc848756916 adapter bus to strap two load buses together. This
adapter bus has ¼" studs on 5/8" centers and allows load lug landings up to 2/0 cable. The return
bus does not require the adapter bus unless 1/0 or 2/0 cable is used and the overlap of the lug
tongue interferes with the adjacent lug. Secure Two-pole adapter busses to the distribution Load
busses and return bus (if desired) as shown in the picture above using 901352617 1/4-20 nuts
provided. Torque to 65 in-lbs using 7/16" socket.
Connect load cables to the adapter bus. The top bus bar has a brown label marked "Return Bus".
901352617 1/4-20 nuts are provided. Torque to 65 in-lbs using 7/16" socket. Secure the Return Load
Cable, then the Load Cable. Cable size is 2/0 AWG or less.
