a) The VA or voltage within the circuit is limited to200 VA or
100 volts by a regulating network complying with the
requirement in 36.12; or
P
b) A fuse or other overcurrent-protective device, other than an
automatically reset type, having a current rating in amperes not
exceeding (100VA)/(Vmax), where Vmax is the maximum rms
voltage of the secondary in question.
P
Maximum available volt-amperes or voltage is to be measured
using a variable resistor connected in place of the circuit in
question, with the primary connected in accordance with 39.1.
For a transformer having multiple secondary windings, all
measurements on one secondary-winding circuit are to be
made with all other windings unloaded.

35.1.14
The acceptability of spacings between live and dead metal
parts connected to the enclosure within an instrument shall be
judged by conducting the applicable dielectric voltage-withstand
test described in Section 43, Dielectric Voltage-Withstand Test.
No dead metal part

Exception: A meter complying with the requirements in the
Standard for Electrical Analog Instruments - Panel Board
Types, UL 1437, is not required to be subjected to a Dielectric
Voltage-Withstand Test.

35.2.1
With reference to 35.1.1 Exception No. 8, the spacing
requirements in the Standard for Insulation Coordination
Including Clearances and Creepage Distances for Electrical
Equipment, UL 840, may be used. The spacing requirements
of UL 840 shall not be used for field wiring terminals or for
spacings to a dead metal enclosure. In determining the
pollution degree and overvoltage category, the end-use
application is to be evaluated and is able to modify those
characteristics given in 35.2.2 and 35.2.3.
N/A
35.2.2
The level of pollution expected or controlled for indoor use
equipment is pollution degree 2. For outdoor use equipment,
pollution degree 3 is expected. Hermetically sealed or
encapsulated enclosures, or coated printing wiring boards in
compliance with the Printed Wiring Board Coating Performance
Test in the Standard for Insulation Coordination Including
Clearances and Creepage Distances for Electrical
Equipment, UL 840, are pollution degree 1.
N/A
35.2.3
It is anticipated the equipment is rated overvoltage category II
and overvoltage category I as defined in the Standard for
Insulation Coordination Including Clearances and Creepage
Distances for Electrical Equipment, UL 840.
N/A
35.2.4
In order to apply Clearance B (controlled overvoltage)
clearances, control of overvoltage shall be achieved by
providing an overvoltage device or system as an integral part of
the product.

35.2.5
For the purpose of applying this alternative, all printed wiring
boards are evaluated as having a minimum comparative
tracking index of 100 without further investigation.
