INSTALLATION
Field Cutting Trac To Special Lengths
(See Figure 7)
NOTE: Cutting should be done from the dead end of
the Trac.
1. Remove dead end fitting and put copper buss
bars and insulators flush with the live end of the
Trac. Measure length from the live end and mark
cut line.
2. Using a hacksaw, cut to desired length. Be sure
to allow 1/8" (3 mm) for dead end fitting which
must be reinstalled to the Trac end.
3. Remove all burrs from the Trac, insulators and
copper buss bars.
4. Push copper buss bars into the insulators 1/2"
(13 mm) from end of Trac.
NOTE: After completing Step 4, buss bar insulators
should be flush with the Trac channel ends, and
copper buss bars should be cut back from each end
of Trac a minimum of 7/16" (11 mm) to a maximum
of 1/2" (13 mm). If this is not the case, make
appropriate modifications.
5. Reinstall the dead end fitting and tighten screw.
IMPORTANT: After Trac has been field cut make
certain that each 4’ (1219) section or less in length
has one mounting hole spaced a maximum of 6"
(152 mm) from each Trac end section. A single
section of Trac that is greater than 4' (1219 mm) in
length must have the mounting hole located a
maximum of 12" (305 mm) from each end of the
Trac with additional mounting holes located a
minimum every 4' (1219 mm) along the length of the
Trac section. Additional openings may be provided
as needed.
If additional mounting openings are required, follow
this procedure in drilling holes:
1. Locate desired mounting holes on the inside
center line of the Trac section.
2. Drill a 3/16" hole through the Trac channel.
CAUTION
For safe and proper operation be careful during
Trac installation that you do not damage the
buss bar insulators during the drilling operation.
If insulators are damaged, discard the section
and do not use.
3. Remove all burrs and proceed to Installing the
Trac.
