TRF No. UL507A
29.6 A motor starting or running capacitor shall be rated
for the appropriate voltage. The maximum available
fault current (AFC) to which it can be subjected
shall comply with one of the following as
applicable:
a)A value of 5,000 A minimum when connected
directly across the line;
b)For capacitors connected in series with a motor
coil, the maximum current available to a short-
circuited capacitor, when connected in series with
the motor coil energized under locked rotor
conditions;
c)For a dry metallized-polypropylene film capacitor
operating at less than or equal to 330 VRMS, a
maximum AFC rating is not required; or
d)For electrolytic type capacitor, a maximum AFC
rating is not required.

30 Spacings P
30.1 The spacings between field-wiring terminals of
opposite polarity, and between a wiring terminal
and any other uninsulated metal part (dead or live)
not of the same polarity, shall not be less than that
specified in Table 30.1. See 14.4.1.
P
30.2 Spacings, other than at field-wiring terminals,
between uninsulated live parts of opposite polarity,
and between an uninsulated live part and a dead-
metal part, shall not be less than the applicable
value specified in Table 30.2. When an uninsulated
live part is not rigidly fixed in position by means
other than friction between surfaces, or when a
movable dead-metal part is in proximity to an
uninsulated live part, the construction shall be such
that the minimum acceptable spacing will be
maintained.
P
30.3 An uninsulated conductor of a rotor circuit shall be
regarded as a dead-metal part with respect to the
stator circuit, and the required spacing shall be
provided between uninsulated stator and rotor
conductors.
