Typical Installations and Raceway Capacities

To eliminate the individual suspension of fluorescent lighting fixtures, and to save labour and material, use Sasco Surface Raceways. When Sasco Strut Channel is in place, fixtures may be installed anywhere along the system. Due to the strength of the Strut Channel, a minimum number of suspension rods are required.


Typical Installations

Note: S158CS-G Closure Strip must be used to form an enclosed raceway. A fixture enclosure may form one face
of the raceway.

"Caution: wiring in raceway shall be rated at not less than 75 °C when electric-discharge lighting fixtures are supported closer than 1/2” (12.7 mm) from the raceway."

 

Wiring Capacity for Types R, RH, RW, T or TW:

Sasco Strut Channel Deflection for a Continuous Row of Fixtures at 15 lbs (7.3 kg) Per Fixture:

When fixtures are spaced 4 feet (1.22 m) apart, the deflection will be approximately 50% of the values for a continuous row. To maintain the above deflection, do not join Strut Channel in mid span.
