Center cable tap box (Figure 28)
Center cable tap boxes are used to center feed a run of busway
with cable and conduit or where loads served by the busway are
connected without the need for overcurrent protection. For indoor
applications, the “T” side, side opposite “T,” and the end panel
are removable for access to the lugs. For outdoor applications,
these panels are gasketed to prevent moisture from entering.
In addition, the outdoor center cable tap boxes are provided with
removable gasketed access panels located on the front and back
for more accessibility to the lugs.
ote:N All dimensions are to the centerline of the Pow-R-Bridge.
