9.2.(b):
A 10-foot expansion gap assembly is installed in the same manner as other 10-foot
sections of conductor bar.
9.2.(c):
For shipping purposes, the gap has been completely closed and must be adjusted
according to the ambient temperature. Maximum hex nut torque is 65 lb-in.
Note: Two sets of anchor hangers are supplied with each expansion assembly. The hangers must be
installed to control expansions.
9.3:
Expansion Gap Settings
The actual gap setting for each ELECTROBAR expansion section is determined by the expected
temperature variance and the ambient temperature at the time of installation. Set the gaps
according to the following chart.

9.4: Anchoring
Requirements
All ELECTROBAR Conductor Bar Systems must be anchored to permit controlled expansion and
contraction of the conductor bar. Anchor all systems according to the following chart. Two
anchor hangers are provided with each ELECTROBAR 10ft. expansion section. Purchase
anchor hangers separately for systems without expansion sections.
Type of System
Anchor Point Locations
All Conductor Bar Systems WITHOUT
Expansion Sections
Place anchors at MIDPOINT of EACH
conductor run
All Conductor Bar Systems with ONE set of
Expansion Sections
Place anchors at MIDPOINT between the
Expansion Sections and EACH end of the
runway
All Conductor Bar Systems with MULTIPLE
(2 or more) Expansion Sections on each
Conductor Run
Place anchors the same as with one Expansion
Section and ALSO at MIDPOINT between
EACH Expansion Section
