TRF No. UL507A
32.2 A resistor, capacitor, inductor, or other part that is
mounted on a printed-wiring board to form a
printed-wiring assembly shall be secured so that it
is not displaced to result in a risk of electric shock
or fire by a force typically exerted during assembly,
normal operation, or servicing of the fan.
P
32.3 Consideration is to be given to a barrier or a
partition that is part of the device and that provides
mechanical protection and electrical insulation of a
component connected to the printed-wiring board.

33 General Purpose Transformer – Insulation Systems N/A
33.1 Class A insulation systems shall consist of a
combination of magnet wire and major component
insulation materials evaluated and found to operate
as intended in its end use. Thermoset materials
and materials in Table 33.1 at the thicknesses
specified are permitted to be used without further
evaluation.
N/A
33.2 For Class A insulation systems employing other
materials or thinner materials than those indicated
in Table 33.1 or a combination of materials, the
materials, whether polymeric or not polymeric
(treated cloth, for example), shall comply with the
requirements in 33.3.
N/A
33.3 A polymeric material employed in a Class 105 (A)
insulation system that isolates the windings from
dead metal parts shall be unfilled or glass-
reinforced nylon, polycarbonate, polybutylene
terephthalate, polyethylene terephthalate, phenolic
or acetal, and shall have a relative or generic
thermal index for electrical properties of 105°C
minimum. Leads shall be rated 90°C minimum.
N/A
33.4 Materials used in an insulation system that
operates above Class 105 (A) temperatures shall
comply with the Standard for Systems of Insulating
Materials – General, UL 1446.
N/A
33.5 All insulation systems employing integral ground
insulation shall comply with the requirements
specified in the Standard for Systems of Insulating
Materials – General, UL 1446.
