Final eld t program
A field fit section of busway is typically an elbow or a short length
of feeder that is intentionally left out of a run for later shipment.
It is most often a mutually agreed upon section between the
customer and the plant. The purpose of the program is to effectively
manage the dimensional uncertainties that may be involved in a
busway layout.
The example shown in Figure 82 identifies the field fit piece as item
F01, a straight length.
Upon release of the order, this item is kept on hold for field
measurement. The contractor installs the busway (Items A01
through A04) and is then able to obtain an exact dimension for the
final field fit piece, Item F01. The measurement should be made from
the edge of the housing of A01 to the edge of the housing A02.
The contractor can fax the dimensions directly to the factory on the
Final Field Fit Fax Release form (see page 53), which is packed
with the original shipment. The field fit section will ship within 5 to
10 working days from the receipt of the release fax. Offset fittings or
more than four field fits released at the same time will ship within
15 working days. This program has been successful for many years
and it provides the assurance of an exact fit the first time. It allows
for busway runs to be released when certain dimensions are not yet
determined. It also eliminates the costly delays that can occur when
sections have to be remade and shipped due to last-minute job site
changes. In turn, this allows for installations to begin early and
projects can be completed on time.
The Final Field Fit Fax Release form is customized to each order and
is shipped to the job site with the busway. The field fit items shown
on the form will match the “F” items shown on the as-built drawings
provided. The sheet is faxed from the job site directly to the product
engineer at the factory.
