Main Bus
When starters are grouped together in a lineup, a typical option is the
main bus. The Cutler-Hammer AMPGARD main bus is mounted in its
own 12-inch (305 mm) high enclosure, which isolates it from the
starter. The connection from the main bus to the starter is done with
rigid vertical bus. Insulated barriers are provided for separate top entry
of power and control cables. The main bus is top, side and front
accessible, which allows for ease of maintenance or extension of
lineup without disassembling the starters.
Main bus is available for 1000, 1200, 2000 and 3000 amperes. Main
bus is uninsulated as standard. Fully insulated bus is an available
option. Bus may be supplied with either tin or silver plating. Crossover
bus, busway entry, and pull boxes are not available for the 3000
ampere design.
The standard bus short circuit rating is per NEMA standards and is
based on the let-through current of the largest fuse used in any starter.
An optional 50 kA, 1-second bus rating is available for customers that
require a higher rating for the main bus.
Vertical Bus
Vertical bus is located behind a fixed barrier in the rear of the enclo-
sure. It is fully insulated as standard, with plating to match that of the
main bus.
UL and CSA Certification
AMPGARD starters are designed, assembled and tested to meet all
applicable standards: NEMA/ANSI ICS3, EEMAC E14-1, UL 347 and
CSA C22.2 No. 14. The major components i.e., contactor, isolating
switch, fuses, MP-3000, IQ DP-4000, and IQ Analyzer are UL recog-
nized.
UL or CSA labeling of a specific starter requires review to ensure that
all requested modifications and auxiliary devices meet the appropriate
standards. Refer to factory when specified. AMPGARD starters meet
the requirements of IEC standards 60694, 60298 and 60470.

Seismic Certification
AMPGARD starters are seismically tested, seismically qualified, and
exceed requirements of both the International Building Code (IBC)
and California Building Code Title 24. Seismic certified starters require
the use of special keyed door latches on the medium voltage doors to
ensure that the doors do not open during a seismic event. No other
special modifications are required.
ABS Certification
Cutler-Hammer AMPGARD Medium Voltage Control assemblies have
been certified under the ABS type approval program. ABS (American
Bureau of Shipping) develops and verifies standards for design,
construction and operational maintenance of marine-related facilities.
ABS Type Approval is a means of demonstrating compliance with
specifications and recording the compliance in the ABS Web site.
AMPGARD is listed in the ABS publications and Web site. AMPGARD
may be used onboard a vessel, MODU (mobile offshore drilling unit)
or facility classed by ABS with two conditions:
1. The AMPGARD assembly may not be used in the propulsion
system.
2. The AMPGARD assembly may not be placed on deck.
The standard AMPGARD assembly will be modified with grab rails,
drip shields, insulated bus, and wind latches for the doors to meet all
the ABS requirements.
Other Optional Features
AMPGARD starters are available with a variety of accessories and
modifications to satisfy a wide range of application requirements.
Some of the broad areas covered include:
Bus and cable entrance enclosures.
Transformers.
Power factor correction capacitors.
Operators and pilot devices.
Instruments and meters.
Control relays and timers.
Solid-state or selected electromechanical protection devices.
