Installing Circuit Breakers and Fuses
Installing Bullet Nose Type Fuseholders and TPS/TLS Fuses
CAUTION!
A 100 A circuit breaker or fuse SHALL HAVE an empty mounting position between it and any other overcurrent
protective device. 100 A circuit breakers can be used without a space provided the continuous current in each 100 A device
does not exceed 64 A. A 175 A or greater circuit breaker SHALL HAVE an empty mounting position between it and any other
overcurrent protective device.
Refer to SAG582127000 for any other restrictions.
Refer to the following procedure and install bullet nose type fuseholders and appropriately sized TPS/TLS fuses into the proper mounting
positions in the distribution cabinet.
Procedure
NOTE: Refer to
as this procedure is performed.
1.
Open the distribution cabinet’s front door by turning the latch in the counterclockwise position.
2.
Orient the fuseholder as shown in
. Insert the terminals on the rear of the fuseholder into their corresponding sockets
on the distribution panel. Ensure the alarm contact on the back of the fuseholder makes contact with the alarm terminal on the
spring strip. Push fuseholder in firmly until fully seated in the distribution panel.
3.
When all fuseholders are installed, install an appropriately sized TPS/TLS fuse in each. To do this, remove the fuse carrier from
the mounted fuseholder body. Hold the fuseholder body while you pull the fuse carrier from the body. Slide the fuse in place
between the contacts of the fuse carrier. When done, push the fuse carrier back into the fuseholder body. Note that a
polarizing key on the bottom of the carrier prevents the carrier from being inserted upside down.
4.
Verify that an 18/100 ampere alarm fuse is present in each fuseholder and that a plastic safety cover is installed on this fuse.
5.
Record all fuse sizes on the label provided on the shield.
6.
Close the distribution cabinet's front door. Turn the latch clockwise to secure the door.
