 The maximum width non-standard wire connector (tang-type) or bus bar connector that
can be used without reducing electrical clearance and creepage distances between
phases is 1.690 inches.
 No hardware or connector should be installed in a manner to reduce the electrical
clearance between the underneath side of the phase termination (line or load) and
ground without the addition of supplementary insulation.
 The metric conductor sizes indicated are the minimum/maximum sizes that can be
inserted in the terminal. Larger size conductors may be required to satisfy ampacity
requirements for local installation rules.

control manual operation of the circuit breaker . The circuit breaker
handle has three positions, two of which are shown on the cover
275 (31.1)
with raised lettering to indicate ON and OFF . On the handle, ON,
275 (31.1)
OFF and Trip are also shown by a color-coded strip for each circuit
breaker handle position: red for ON, white for Tripped and green for

Circuit Breaker Reset
After a trip operation, moving the circuit breaker handle to the Reset
(extreme OFF) position resets the circuit breaker .
N
otee:
In the event of a thermal (overload) trip the circuit breaker cannot be
reset immediately . In a breaker with a thermal-magnetic type trip unit the
thermal element needs to cool (up to approximately five minutes) before it
can be reset .
No circuit breaker should be reclosed until the cause of trip is
known and the situation rectified .
PUSH-TO-TRIP Button
The PUSH-TO-TRIP button operates the circuit breaker tripping func-
tion and may be periodically used to exercise the operating mecha-
nism . In thermal magnetic trip units, the button is designed to be
operated by a small screw- driver .
Thermal-Magnetic Trip Unit Adjustment
The magnetic element of each pole of the trip unit is adjusted by
rotating the adjustment buttons on the front of the trip unit with a
screwdriver . The buttons have several settings as indicated on the
nameplate with values in multiples of the trip unit ampere rating (I
To adjust the setting, rotate each button clockwise until arrow on
button points to desired setting . The molded case switch is set at
the factory (at 8X) and is not field adjustable .
Interchangeable Trip Units
