TRF No. UL507A
31.5.4A primary or secondary circuit fuse or other
such circuit protective device meets the intent of
limiting the maximum available volt-ampere
capacity in accordance with 31.5.1. While there are
no restrictions on the current rating of this
protective device as long as it limits the available
secondary volt- ampere limit in accordance with
31.5.2, the protective device shall comply with the
requirements of this Standard and shall be
provided with an adjacent replacement marking or
replacement instructions that includes the required
voltage and current rating. The printed wiring
board, wiring, and spacings prior to the point at
which the voltage and volt-ampere capacity are
suitably limited shall comply with the requirements
of this Standard.
N/A
31.6 Limiting impedance circuit requirements N/A
31.6.1 A limiting impedance circuit shall be supplied by an
impedance that complies with the following:
a)The calculated power dissipation of the
impedance, as the result of a direct short applied
across the circuit downstream of the impedance,
does not exceed the power rating of the
impedance;
b)The power dissipation of the impedance is not
greater than 15 Watts; and
c)There does not exist a risk of shock, as defined in
2.3.16, downstream of the impedance.
N/A
31.6.2 The limiting impedance referred to in 31.6.1 shall
be able to function under single component fault
conditions.
N/A
32 Printed-Wiring Boards V-0 used P
32.1 A printed-wiring board shall comply with the
requirements in the Standard for Printed-Wiring
Boards, UL 796, including direct support criteria,
and shall be classed V-0, V-1, or V-2 in
accordance with the requirements in the Standard
for Tests for Flammability of Plastic Materials for
Parts in Devices and Appliances, UL 94.
