XAP Series Busduct
Storage, Installation, and Maintenance
Installation
One set of construction drawings is sent with the initial shipment of
each busduct order. This drawing package will contain the layout of each
run, showing where each piece of the run is located, and other possible
cut sheets and instructions. The installer should review these drawings
prior to and during installation to ensure proper installation.
Identification
Each piece of the Eaton XAP busduct has a nameplate label as shown in
Figure 1. This label identifies each piece and its ratings. It is recommend-
ed that each piece be installed sequentially, starting at the beginning
point of the run. This would typically be the cable tap box, transformer,
switchboard, or switchgear connection.

Phasing and Orientation Labels
Each piece of the Eaton XAP busduct has “N” labels as shown. The "N"
label indicates phasing. From the “N” side of the busduct, the standard
phasing is N-L3-L2-L1-PE.
Figure 2. Phasing and Orientation Label
The XAP busduct construction is not symmetrical. It is imperative for
all sections of the busduct to be installed with all of the labels aligned
and consistent throughout the run and per Eaton-supplied construction
drawings. Failure to do so may result in damage to the busduct as well
as property damage, physical harm or death.
Joint Installation
When connecting pieces of the Eaton XAP busduct together, make
certain that contact surfaces are clean and free from contaminants.
Some section may have electrical lubricant on the contact surfaces,
which was applied by the factory. This will aid in joint installation. Align
the left end of one section to the right end of the adjoining section with
the "N" label in alignment. Figure 3 illustrates correct joint installation.

Torque Indication Bolt
When the two sections have been properly joined together, the joint
bolt may be tightened. This joint bolt is a special torque-indicating bolt
with two bolt heads to ensure that the proper installation torque is
achieved. Fall away instruction tags are provided between the upper
and lower bolt heads. Torque should only be applied to the upper bolt
head. When the proper torque is achieved, this bolt head will shear off,
allowing the tag to fall to the floor.
Figure 4. Torque Indicating Bolt as Shipped
Figure 5. Torque Indication Bolt after Installation
Any joint bolt that is improperly tightened will retain the highly visible tag
and should be retightened. The lower bolt head remains intact for future
maintenance.
DANGER
FAILURE TO INSTALL THE BUSDUCT CORRECTLY MAY RESULT IN
DAMAGE TO THE BUSDUCT AS WELL AS PROPERTY DAMAGE, PHYSICAL
HARM, OR DEATH.
