25.2 The fused attachment plug, fuseholder, or in-line
fuseholder shall be constructed such that there
shall not be exposure of live parts during removal
or replacement of the fuse(s). In addition, for a
fused attachment plug, there shall not be exposure
of live parts with the fuse cover partially open
during 2.03 mm (0.08 inch) insertion into a
receptacle. Exposure of live parts shall be
determined by contact with the accessibility probe
illustrated in Figure 10.1.

26 Motor Overload Protection P
26.1 As referenced in the Exception to 23.1, integral
thermal protection is not required when the
protection is provided by a separate device that is
responsive to motor current and is rated or set to
trip at not more than the percentages of the motor
nameplate full-load current rating specified in
Column A of Table 26.1.
P
26.2 When the overload device, selected in accordance
with Column A of Table 26.1, is not sufficient to
start the motor or to carry the load, the next higher
size device shall be permitted to be used when the
trip current of the overload device does not exceed
the percentage values specified in Column B of
Table 26.1.
P
26.3 A three phase motor shall be provided with
overload protection as follows:
a)Three overcurrent units; or
b)Thermal protectors as described in 23.1(a), a
combination of thermal protectors and overcurrent
units, or another method of protection, where the
specific protective arrangement has been
investigated and found to provide protection under
primary, single-phase failure conditions when
power is supplied from transformers connected
wye-delta or delta-wye.
