The Standard for Tests for Safety-Related
Controls Employing Solid-State Devices, UL 991.
When the protective electronic circuit is relying
upon software as a protective component, it shall
comply with the requirements in the Standard for
Software in Programmable Components, UL 1998.
If software is relied upon to perform a safety
function, it shall be considered software Class 1
N/A
The Standard for Automatic Electrical Controls for
Household and Similar Use, Part 1: General
Requirements, UL 60730-1. If software is relied
upon to perform a safety function, it shall be
considered software Class B; or
N/A
Exception: Compliance with the above standards
is not required for an electronically protected motor
circuit if there is no risk of fire, electric shock, or
injury to persons during abnormal testing with the
motor electronic circuit rendered ineffective;
compliance with the applicable requirements of
this standard is then required
N/A
28.3.8
Motors indicated below are not required to comply
with the overload protection requirement:
N/A
Motors that are supplied by Class 2 circuits
N/A
Motors rated less than 1 horsepower and Which
are manually started
N/A
28.3.9
Running overload protection is not required for the
following constructions
N/A
A motor that is used for air-handling only when the
blower or fan impeller is coupled directly to the
motor shaft or
N/A
A shaded-pole motor with a 2:1 or smaller ratio
between locked-rotor and no-load currents and a 1
ampere or smaller difference between no-load and
locked-rotor currents
N/A
28.3.10
An overload-protective device that complies with
the National Electrical Code, ANSI/NFPA 70, is
determined to comply with 28.3.1. This overload-
protective device shall be responsive to motor
current and rated or set as specified in Column A
of Table 430-72(b) of the NEC. When the rating of
the motor-running overload protection determined
in accordance with the foregoing does not
correspond to a standard size or rating of a fuse,
nonadjustable circuit breaker, thermal cutout,
thermal relay, or heating element of a thermal-trip
motor switch, the next higher size, rating, or
setting is not prohibited from being used, and shall
not be more than that specified in Column B of
Table 430-72(b) of the NEC. For a multi- speed
motor, each winding connection is to be evaluated
separately
