TRF No. UL507A
54.4 The strain relief means provided in a through cord
switch shall withstand for 1 minute a direct pull of
133.44 N (30 pounds). The strain relief is not
acceptable when a conductor is detached from a
terminal or an uninsulated conductor of the cord is
exposed.
P
54.5 For the construction mentioned in 15.2.3, six
samples of the clamp that have been secured to
the cord in the intended manner are to be used.
Three samples are to be subjected to the dielectric
voltage withstand test specified in Section 47,
Dielectric Voltage Withstand Test, and shall then
comply with the strain-relief test specified in 54.1 in
the as-received condition. Three samples shall
comply with the requirements specified in 54.1 after
being subjected to the following procedures:
P
The samples are then to be subjected to the
dielectric voltage withstand test specified in Section
47, Dielectric Voltage Withstand Test, with the
value of the applied potential based on the rating of
the appliance. The potential is to be applied
between conductors, and the potential is also to be
applied between the clamp and all conductors
spliced together.
P
55 Interconnecting Cords and Leads P
55.1 Each lead or flexible cord provided for wiring
between components or for interconnection
between parts of a motor, (e.g. motor windings to
capacitor, motor connections to receptacle, light
connections to receptacle, etc.) shall be subjected
to the test described in 54.1 and 54.3 except that
the pull shall be 20 pounds (89 N). Each lead or
cord is to be tested with the 20-pound (9-kg)
weight.
P
56 Unguarded Impeller Tests N/A
56.1 An impeller of a portable fan not required to be
guarded shall not break, crack, or chip when
operated for 1 hour connected to a supply voltage
of 130 percent of the rated supply voltage. The test
is to be conducted before and after conditioning as
described in 56.2.
