Installing Spectra Series™ Busway
 
Storage Precautions 
Before storing, unpack sufficiently to make a 
check of the busway for possible concealed 
damage resulting from shipping and handling. If 
damage has occurred, notify the shipper 
immediately. If the busway is free of damage, 
restore the packing until ready for installation. 
 
Store indoors in a clean, dry area, preferably close 
to the installation points. 
 
Protect the busway from mechanical damage and 
any contact with or exposure to corrosive fumes, 
liquids, salts, or concrete. 
 
Failure to store and protect the busway properly 
can cause serious damage and will void the 
warranty. 
NOTE: No busway, including outdoor rated, is 
weatherproof until completely and properly 
installed. 
NOTE: Aucune canalisation pour barres omnibus, 
incluant celles classées pour l'extérieur, n'est à 
l'épreuve de l'eau jusqu'à ce qu'elle soit installée 
complètement et correctement. 
 
Pre-Installation Procedure 
When possible, deliver the busway to its 
installation location before unpacking. Large 
labels on each shipping carton or crate designate 
the items contained. Additionally, each busway 
piece is identified with an item number label. 
 
Inspect each busway piece for possible damage 
or contamination. Contact surfaces must be clean. 
However, do not attempt to polish tarnished 
contact surfaces. 
 
Check to ensure that joint insulators are not 
damaged or cracked and are firmly in place. 
 
Megohm test each piece before installation. 
Installation of Spectra Series Busway 
Establish the bus bar phase sequence (Ø side is 
labeled) to determine how the busway is to be 
installed, so that correct phasing is maintained 
throughout the system. Note that phase 
transposition lengths, when furnished, may 
relocate the Ø to the opposite side of a busway 
run. 
 
Each busway piece has a ―bar end‖ and a ―joint 
end,‖ as illustrated in Figure 1. Normally the 
busway is oriented end for end with bar ends 
pointing away from the source. Also, the ø side 
should be oriented down for horizontal plug-in 
applications.

In vertical riser installations, it is easier to lower 
the busway into place than it is to raise it. 
 
If installation drawings have been furnished, 
information regarding the orientation of the 
busway and location of the ø side, as well as other 
pertinent data, will be furnished. These drawings 
should be followed carefully to ensure a proper 
busway system. 
 
Where to Start 
Start the installation, if at all possible, at the most 
critical point, such as a main feed box, 
switchboard or switchgear, elbow, or other critical 
fitting or termination.
