Sentron Busway Systems
Sentron Busway Overview
Revised on 04/30/18
Overview
Joint Stack
Each Sentron Busway piece is shipped
with a joint stack and joint covers
installed at one end of the busway and a
shipping end protector at the other end.
The joint stacks feature a single bolt
design and a special, torque indicating,
double headed break-off bolt. This
eliminates the need for torque wrenches
and assures proper torque at installation
of 50 ft.-lbs.(68 N-m).
When the proper torque value is
achieved, the top bolt head will shear
off. Each joint stack allows for +/- .625
inches (15.8mm) adjustability at each
joint. Over adjustment is prevented by
the joint covers, which will only allow a
.625 inch (15.8mm) adjustment when
the knockouts on the joint cover are
removed.
It is possible to remove any joint
connection assembly to allow electrical
isolation or removal of a busway length
without disturbing adjacent busway
lengths. Isolation joint stacks are
available and used to electrically isolate
a busway section(s) within a busway
run. For easy visual identification,
isolation joint stack assemblies are
painted white.
Joint Assembly

Each plug-in opening has a reversible
hinged dead front designed to protect
the contact surfaces from dirt, dust or
moisture. Gasketing is used where

to insure integrity of insulation. In
addition, Sentron Busway is tested in
accordance with both UL and IEC
standards. All Sentron Busway is
manufactured and inspected in an ISO
