Cable Stackers
SI-1 and SIFS-1
Application The 3M™ Cable Stacker SI-1 and 3M™ Furring Strip Cable Stacker SIFS-1 are
intended for use with NM and UF cables on framing members. SI-1 allows the
installation of multiple NM or UF cables on one side of a 2 x 4 in vertical or horizontal
raceways. SIFS-1 allows multiple cable installations on one side of a furring strip.
The cable stackers address Article 300-4 (d) of the National Electrical Code (NEC)
and the Canadian Electrical Code, Part 1, Section 12-516.

Test Method Two 3M™ Cable Stackers SI-1 were mounted 4 feet apart on standard construction
wood 2 x 4’s.
Copper conductor NM cables were installed with thermocouples on the black
circuit conductors. Each was located within the cable stacker.
Black and white circuit conductors for each cable size were connected in series.
Tests were conducted with the cable assemblies in both the horizontal and vertical
positions.
Temperature Rise Test
*Multiplication Factor of 1.08 from Table 310-16, 60°C column, 1990 NEC
**If 5 to 8 # 14-2 w/g NM cables are installed in a SI-1 cable stacker, ampacity
Derating should be considered.
