TRF No. UL507A
31.2.1 The following applies to secondary circuits that
comply with the Class 2 requirements of 31.3.1 or
the limited voltage/current requirements of 31.4.1 –
31.4.7:
a)Components located within these circuits are not
required to be evaluated.
b)Spacings located within these circuits and from
these circuits to earth ground or to the enclosure
are not required to be evaluated. However,
spacings from these circuits to other circuits shall
be in accordance with Spacings, Section 30.
c)These circuits are not prohibited from being
accessible from outside the enclosure.
N/A
31.2.2 The following applies to secondary circuits that
comply with the limited energy requirements of
31.5.1 – 31.5.4 circuit requirements and that
involve open circuit potentials less than or equal to
30 V ac or 42.4V peak:
N/A
a)Components located within these circuits are not
required to be evaluated.
N/A
b)Spacings located within these circuits and from
these circuits to earth ground or to the enclosure
are not required to be evaluated. However,
spacings from these circuits to other circuits shall
be in accordance with Section 30, Spacings.
N/A
c)These circuits shall not be accessible from
outside the enclosure. Therefore, when these
circuits provide power to components that extend
through the enclosure, the ability of these
components to serve as an enclosure shall be
evaluated.
N/A
31.2.3 The following applies to secondary circuits that
comply with the limited energy requirements of
31.5.1– 31.5.4 and that involve open circuit
potentials in excess of 30 V ac or 42.4 V peak:
N/A
a)Components located within these circuits are not
required to be evaluated.
N/A
b)Spacings located within these circuits are not
required to be evaluated. However, spacings from
these circuits to earth ground or to the enclosure
and spacings from these circuits to other circuits
shall be in accordance with Spacings, Section 30.
