SpecMate™Wireway Systems

INSTALLATION INSTRUCTIONS

SpecMate Type 1 Wireway is provided in sizes ranging
from 2" to 24" [51mm to 610mm] wide and from 2" to
12" [51mm to 305mm] deep, with a hinged cover. The
Wireway may be provided with barriers. All SpecMate
Wireway is listed by Underwriters Laboratories under
File No. E137690 and CSA Certified under File No.
LL59760 in compliance with the National and Canadian
Electrical Code.

Typical Installation: The Wireway shall be installed as a complete system incorporating all fittings necessary to provide for directional
changes. All connections shall be fastened securely with the fasteners provided by the manufacturer in order to ensure compliance with
UL and CSA bonding requirements. Conductors of appropriate types as outlined by the applicable Electrical Code may be used in the
Wireway following installation. Specific installation instructions are given below.

Hanging Method: Three styles of hangers may be purchased with SpecMate Wireway Systems.

“C” Hanger: For widths up to 12" [305mm]. Trapeze Hanger: For any size of Wireway.

Wall Bracket: For installations along walls.

For any size of Wireway.

Installation of couplings:

Installation of end blanks:

Coupling: Couplings are provided with necessary hardware. Slide
the coupling into the end of the wireway and tighten the fasteners with
a wrench, ensuring they are secure. Slide the end of the next length of
wireway over the other half of the coupling and attach the fasteners.
Repeat until complete. Couplings are best located at 1/4 of the dis­tance between supports (hangers).

End Blank: End blanks provided with necessary hardware. Slide the
end blank into the end of the wireway and tighten the fasteners with a
wrench, ensuring they are secure.

Installation: For “C” Hangers, Trapeze Hangers, threaded rod should be cut to the appropriate length and fastened to a structural
member. The hanger should then be bolted to the threaded rod through the holes provided, ensuring that it is level and in line with the
other hangers. Wall-mounted hangers should be fastened to structural members in the wall in a manner ensuring sufficient support
strength. Once the Wireway is in place, it must be fastened to the hanger by any structurally sound method. Most installations use
1/4" [6.4mm] nuts and bolts, fastened through holes drilled in the Wireway Base. No sharp edges shall be allowed in the Wireway as
a result of fastening. Fastening hardware for hangers is not provided. UL listed Wireway with square cross sections of 2.5, 4, and 6
inches [64, 102 and 152mm] may be supported on maximum spans of 10 feet [3 meters]. All other Wireway shall be supported on
spans of 5 feet [1.5 meters] or less.

Installation of Tele-Power Pole Adapter:

1. Locate the Pole Adapter on the Wireway.

Drill holes in the appropriate locations to
match the holes in the Pole Adapter.
Cut and grommet hole to match Pole
Adapter Entrance Feed.

2. Bolt the Pole Adapter to the underside
of the Wireway. No sharp edges
should remain in the Wireway. (Bolts
not furnished.)

3. Insert the Wiremold NP600 Series Tele­Power Pole into the underside of the
Pole Adapter. Tighten the two set
screws (furnished) onto the pole.

National Electrical Code (NEC):

Article 362-5 of the NEC (1999) states that “The sum of cross-sectional areas of all contained conductors at any cross section of
the wireway shall not exceed 20 percent of the interior cross-sectional area of the wireway” and that “Wireways shall not contain
more than thirty current carrying conductors at any cross section.” An important exception to this is that “where the derating factors
specified in Article 310 – 15(b)(2)(a), are applied, the number of current-carrying conductors shall not be limited, but the sum of the
cross-sectional areas of all contained conductors at any cross section of the wireway shall not exceed 20 percent of the interior
cross-sectional area of the wireway.”

Where the conductors enter the wireway through the bottom or the sides, the maximum conductor size is limited due to the need
to control the bend radius of the conductor. See the chart entitled “Conductor Size Based on Bending Space,” for the maximum
conductor size applicable for this situation.

Please see Article 362 of the NEC for more details if required.

Canadian Electrical Code (CEC):

The rules in CEC 12-2104 regarding conductors in wireways are as follows:

(1) Conductors used in wireways shall be the insulated types indicated in Table 19 (CEC) as being suitable for use in raceways.
(2) Except as permitted in Subrule (4) wireways shall contain not more than 200 conductors and the aggregate cross-sectional

area of the conductors and their insulation shall not exceed 20% of the interior cross-sectional area of the wireway.
(3) No conductor larger than 500 kcmil (MCM) copper of 750 kcmil (MCM) aluminum shall be installed in any wireway.
(4) Wireways containing only signal and control conductors may contain any number of conductors but the aggregate cross-

sectional area of the conductors and their insulation shall not exceed 40% of the interior cross-sectional area of the wireway.
(5) The cross-sectional area for conductors in Subrules (2) and (4) shall be determined in accordance with Rule 12-1014(4).

Please see Section 12-2100 of the CEC for more details if required.
Conductor size is based upon the bending space.

Exception: Conductors that enter only at the ends of the run are limited in size only by the 20% fill requirements of the National and

Canadian Electrical Codes.
