SECTION 1 GENERAL INFORMATION
GE Conversion Kit installation is straightforward, but does
require careful workmanship and attention to these
instructions. Familiarity with the breaker itself is highly
desirable. The general approach is to first strip the breaker
of its existing trip devices, then install the
MicroVersaTrip
®
Plus or MicroVersaTrip
®
PM kit
components. Following this procedure, the converted
breaker is performance tested, prior to restoring the breaker
to service.
The majority of breaker kit installations do not require any
customized assembly work. However, some conversions
may involve unusual mounting circumstances or accessory
combinations which necessitate minor modification and/or
relocation of a component(s). In most instances this
supplementary work can be done on site.
Preparatory to the conversion, the installer should verify
that the appropriate current sensors and programmer unit
have been furnished. Whenever the ground fault trip
element is furnished for breakers applied on 4-wire
systems, note that an associated neutral sensor (CT) is
required for separate mounting on the equipment. Make
sure that retrofitted breakers are applied within their short
circuit rating. For example, when the trip elements of the
breaker are to be changed from long-time instantaneous to
long-time short-time, the short-time rating would govern
the application. As a service-related consideration, the
installation of the MicroVersaTrip
®
Plus or
MicroVersaTrip
®
PM kits provides an excellent
opportunity to perform normal maintenance on the breaker,
particularly when the front and back frames are separated.
Such procedures are described in the installation and
maintenance manuals normally supplied with the Breakers
and Equipment.
SECTION 2 PRIOR TO INSTALLATION
Before starting any work, turn off and lock out all power
sources leading to the breaker (primary and secondary).
Remove the breaker to a clean, well lighted work area.
WARNING: LOW VOLTAGE POWER CIRCUIT
BREAKERS UTILIZE HIGH SPEED, STORED-
ENERGY OPERATING MECHANISMS. THE
BREAKERS AND THEIR ENCLOSURES CONTAIN
INTERLOCKS AND SAFETY FEATURES
INTENDED TO PROVIDE SAFE, PROPER
OPERATING SEQUENCES. FOR MAXIMUM
PERSONNEL PROTECTION ASSOCIATED WITH
INSTALLATION, OPERATION, AND
MAINTENANCE OF THESE BREAKERS THE
FOLLOWING PROCEDURES MUST BE
FOLLOWED. FAILURE TO FOLLOW THESE
PROCEDURES MAY RESULT IN PERSONAL
INJURY OR PROPERTY DAMAGE.
• Only qualified persons, as defined in the National
Electrical Code, who are familiar with the installation
and maintenance of low voltage power circuit breakers,
and switchgear assemblies, should perform any work
associated with these breakers.
• Completely read and understand all instructions before
attempting any breaker installation, operation,
maintenance, or modification.
• Turn off and lock out the power source feeding the
breaker prior to attempting any installation,
maintenance, or modification. Follow all lockout and
tagging rules of the National Electrical Code and all
other applicable codes.
• Do not work on a closed breaker or a breaker with the
closing springs charged. Trip OPEN the breaker and
be sure the stored energy springs are discharged
avoiding any possibility that the breakers may trip
OPEN or the closing springs discharge, causing
injuries.
• For both stationary and draw out breakers, trip OPEN,
then remove the breaker to a well lighted work area
before beginning any work.
• Do not perform any maintenance including breaker
charging, closing, tripping, or any other function which
could cause significant movement of the breaker while
it is on the draw out extension rails.
• Do not leave the breaker in an intermediate position in
the switchgear compartment. Always leave it in the
CONNECTED, TEST, or DISCONNECTED position.
Failure to do so could lead to improper positioning of
the breaker and flashback.
