8. Raise the lift truck platform to
disengage the lift truck locking tabs,
release the foot brake and pull the lift
truck away from the frame.
The breaker interlock tabs
must engage the slots in the
lift truck platform before
releasing the foot-brake
and moving the lift truck.
Lower the lift truck platform
before transporting draw-
out modules from upper
positions with the lift-truck.
Standard Construction
4.12 Standard Color
The standard paint color is ANSI #61. This
finish is electro-static powder paint applied
over an iron phosphate coating. This
process achieves a smooth, uniform paint
finish that conforms to all UL requirements.
4.13 Galvanized Steel Frame
Construction
Unpainted parts are made of galvanized
steel. Galvanized steel greatly exceeds the
paint qualifications of ANSI C37.20.2
Section 5.2.8.
4.14 Primary Disconnect Assemblies
Circuit breaker primary disconnects consist
primarily of a circle of fingers compressed
by a garter spring. The springs are outside
the current path. The fingers can be
inspected by withdrawing the unit. The
primary contacts are high pressure, self-
aligning devices. All parts are plated to
reduce electrical resistance.
4.15 Secondary Disconnecting Devices
Circuit breakers have self-aligning
disconnects sized for the required current.
They make contact in the CONNECTED
and TEST positions, without the need for a
test jumper (see Figure 27).

4.16 Ground Bus Contacts
The ground bus contacts are under the
circuit breakers. The circuit breakers are
grounded in all positions (see Figure 27).
