65.8 The supply circuit is to have branch circuit
overcurrent protection, the size of which equals
125 percent of the input current rating (20-ampere
minimum). When this value does not correspond
with the standard rating of a fuse or a circuit
breaker, the next higher standard device rating
shall be used. The test voltage and frequency are
to be adjusted to the maximum rated voltage of the
fan.
P
65.9 A fuse that is replaced during routine maintenance
is to be defeated unless marked in accordance with
81.8. A fuse that is soldered in place, or is located
such that it is accessible only to qualified service
personnel, and marked in accordance with 81.8,
and any other overcurrent protective device not
subject to replacement during routine maintenance
is to be left in the circuit.

65.10 Each abnormal condition is to be conducted for 7
hours or until one or more of the following results
are observed:
P
a)A risk of fire or electric shock develops (see
65.2);
P
b)The branch-circuit fuse opens; N/A
65.11 The overheating of parts referred to in 65.10(d) is
to be detected by an indicator such as an odor,
smoke, discoloration, cracking of materials,
charring, flaming, glowing, arcing, changes in
circuit current through the applied fault, or any
similar phenomenon.
N/A
65.12 When a fault condition is terminated by the opening
of a circuit component, the test is to be conducted
two more times using new components for each
test.
N/A
66 Fuseholder Cover Test N/A
66.1When required by 25.3, an open cover shall be
subjected to a force of 36 N (8 lbs) applied for 1
minute in any direction that the cover may be
removed, the open cover of a fuseholder, fused
attachment plug, or current tap, or similar device,
shall not detach from the body of the device. One
fuseholder is to be tested.
