TRF No. UL507A
34.1 Malfunction of a component such as a diode, a
transistor, a thyristor, an electrolytic capacitor, an
integrated circuit, an optical isolator, or other solid-
state device (any device whose operation is
dependent upon any combination of optical,
electrical, or magnetic phenomena within a solid)
that has not been investigated for reliability and
determined to be reliable shall not result in a risk of
fire, electric shock or injury to persons when
subjected to the Component Breakdown Test in
Section 65.
P
34.1 Compliance with 34.1 requires an analysis of the
circuit to determine whether malfunction of a
component results in a risk of fire, electric shock or
injury to persons. This analysis requires the
opening and short circuiting of a component
(electrolytic capacitor, transistor junction, and the
like) and observation of the ultimate results of the
simulated malfunction or breakdown. Only one
condition of simulated malfunction or breakdown is
to be imposed at a time.

35 Grounding P
35.1 General P
35.1.1 In addition to the requirements specified in 35.1 –
35.3, an appliance shall comply with the applicable
requirements in 14.4.1 – 14.4.10, 14.5.5, and
14.5.6.
P
35.1.2 Electrical continuity shall be provided between all
exposed dead-metal parts and all dead-metal parts
within the enclosure that are exposed to contact
during any user-servicing operation and that can
become energized and:
P
a)The equipment grounding terminal or lead, and
to the metal surrounding the knockout, hole,
bushing, or metallic fitting (at the end of flexible
armored cable for attachment to a field-provided
metallic outlet box) provided for field power-supply
connection for an appliance intended for
permanent electrical connection; or
P
b)The point of connection of the grounding
conductor of the power-supply cord of an appliance
equipped with a power-supply cord of the
grounding type. See 35.3.1.
