44.2 The fuse mentioned in 44.1(b) is to be other than a
time-delay type. The current rating of the fuse is to
be equal to the current rating of the supply circuit of
the lowest rating to which the appliance is intended
to be connected.
P
44.3 To determine whether an appliance complies with
the requirements in 44.1, the appliance is to be
connected to a power-supply circuit protected by a
fuse as specified in 44.2 or in the exception to
44.2, whichever applies. The appliance is to be at
room temperature at the beginning of the test. The
appliance is to be started three times without
tripping an overload protector provided as part of
the appliance, or opening the fuse protecting the
supply circuit. Each start of the appliance is to be
made under conditions representing the beginning
of normal operation – the beginning of the normal
operating cycle in the case of an automatic
appliance. The motor of the appliance is to be
allowed to come to full speed after each start, and
to come to rest between successive starts.

45 Input Test P
45.1 The current input to an appliance shall be not more
than 110 percent of the rated value when the
appliance is operated under conditions of intended
service, when connected to a power-supply circuit
at the test voltage shawn in Table 40 1 rated fre

46 Temperature Test P
46.1 All fans P
46.1.1 When tested as described in 46.1.3 – 46.2.2, an
appliance shall not:
P
a)Attain constant temperatures at any point on the
fan sufficiently high to result in a risk of fire;
P
b)Cause deterioration of any materials employed in
the appliance; or
P
c)Have constant temperature rises at specific
points (particularly those surfaces that may be
contacted by the user with the fan operating as
intended) more than those specified in Table 46.1.
(See 46.1.12.)
