ALA4800 ALUMINUM RACEWAY
Installation

Instructions

The ALA4800 is a permanent two-channel raceway that is versatile
enough to accomodate power, data or telecommunication wiring.

NOTE: Cross-sectional area of each compartment indicated.

Wiremold Electrical Systems conform with, and should be installed and properly grounded in compliance with requirements of the current
National Electrical Code or codes administered by local authorities.All electrical products may represent a possible shock or fire hazard if improp­erly installed or used.Wiremold electrical products are UL listed, made for interior use in a dry location and should be installed by qualified elec­trical people in conformance with current local and/or the National Electrical Code.

At 90° Outside Corner, position ALA4818
External Elbow at end of ALA4800B-10
Base. Slide other base section to other end
of ALA4818. Center couplings on joints
and tighten screws. After wiring system,
snap on ALA4818 mitered covers.

For retaining wires in long raceway
runs, snap-in ALAWC Series Wire Clips
into ALA4800B-10 Base as required.

Snap ALA4806 Cover Clip over
joints in either ALA4800B Base or
ALAC-5 Cover sections.

ALA4815 Tee: Position fitting at end of ALA4800B-10 Base. Install
other base sections to other ends of the fitting. Center couplings on
joints and tighten screws. Install fitting covers after wiring.

*Capacity range is calculated at 20% to 40% of raceway area as stated in a proposed revisions to the Commercial Building Standard for

Telecommunication Pathways & Spaces, EIA/TIA-569. Actual wire fill capacity may vary based on applications, cable types, and number, as well as
type of fittings. (Fittings may cause additional variances to the fill capacity.)

1 - Provide electrical feed through 1/2" [12.7mm] or 3/4"

[19.1mm] KOs in ALA4810B2 End Cap.

2 - Attach base section to mounting surface by drilling

9/32" [7.14mm] holes in the base then fastening with
#8 flat head screws.

3 - Secure conductors in place with ALAWC Wire Clip.

4 - Join additional raceway sections with two ALA01 Couplings.
5 - Close ends with ALA4810B2 End Caps.
6 - Snap ALAC-5 Cover into ALA4800B-10 Base to

complete installation.

To attach ALA4800B-10 Series Base sections to mounting
surface; drill 9/32" [7.14mm] holes in the base (approx.
18" [457mm] O.C.). Fasten Base with #8 flat head screws.

Base Sections

At ALA4800B-10 Base section butt joints: slide two ALA01
Couplings into first base section. Mount next base to surface.
Center couplings on joint. Tighten locking screws.

Position ALA09 Ground Clamp
into ribs in ALA4800B-10 Base.
Fasten mounting screw. Attach
ground wire using brass cup
washer & green hex nut to
ground lug.

At 90° turn on same surface, position ALA4811 Flat Elbow at end of
ALA4800B Base. Position next base section onto other end of ALA4811.
Center couplings over base joints and tighten screws. Install ALA4811 Covers
and ALA4800 Series Covers as shown after wiring.

For connecting a vertical run of
ALA4800B with a horizontal overhead
run with its cover facing up. Assemble
ALA4817N to raceway bases with
ALA01 Couplings included.

Install one side of ALA417A Internal Coupling,
BEFORE mounting raceway base. Fasten first base sec­tion to wall, then slide adjoining base onto coupling
legs. Tighten all four coupling screws.

Install ALA4817 to first raceway base, BEFORE mount-
ing raceway base. Fasten base section to surface. Butt
next section of base. Center couplings over base joints,
tighten set screws.
