and develop a standard. Although CSA administers the process and establishes rules to promote fairness in achieving consensus, it does
not independently test, evaluate, or verify the content of standards.

8.8.2
Minimum spacings for other than field-wired branch circuit supply terminals, between uninsulated live
parts of opposite polarity, between an uninsulated live part and a grounded dead-metal part, and between
an uninsulated live part and an accessible dead-metal part shall be in accordance with Table 7.

Table 7
Spacings other than field-wiring branch circuit supply terminals

(See Clauses 8.8.2 and 8.11.2.4.)

8.8.3
Minimum spacings on printed wiring boards and for board-mounted components, between uninsulated
live parts of opposite polarity, between an uninsulated live part and a grounded dead-metal part, and
between an uninsulated live part and an accessible dead-metal part shall be in accordance with Table 5.
Notes:
(1) Other than for wiring terminals or spacings to a dead-metal conductive enclosure, spacings may be in accordance with

CSA C22.2 No. 0.2. Overvoltage Category II applies to circuits directly connected to the supply source. Printed wiring
boards usually have a minimum CTI of 100, unless known to be greater.

(2) Spacings between uninsulated live parts of different voltage on non-conformal coated printed wiring boards, their
connectors, and board-mounted electrical components wired on the load side of line filters or similar voltage peak
reduction networks and components, may be 0.58 mm (0.0230 in) plus 0.005 mm (0.0002 in) per V peak.

(3) Encapsulated parts, inherent spacings of discrete components, along with other conductive parts at their point of
connection to these discrete components, and circuits supplied by a Class 2 or LVLE source are to be exempt from
spacing requirements.

(4) Compliance with the dielectric withstand test specified in Clause 9.4 is to be accepted as an alternative means to
determine compliance of spacings between any uninsulated live part and any dead metal part.

8.8.4
Enameled and similar film-coated wire shall be identified as an uninsulated live part.

8.8.5
The spacings between output circuitry and dead metal for a ground-referenced circuit shall be based on
the maximum open-circuit voltage to ground.

8.8.6
Parts subject to movement relative to other parts shall be positioned in their most severe orientation
before spacings are measured, unless reliably held in place.

8.9 Circuit components

8.9.1
A fixed resistor, semiconductor, thermistor, positive temperature coefficient (PTC) or negative temperature
coefficient (NTC) resistor, or the like (relied upon to limit the output of a unit or otherwise achieve
acceptable performance) shall have permanence and stability that do not decrease its limiting capabilities
over time and use. Among the factors considered when evaluating a limiting component are
(a) the cumulative effects of temperature;
(b) electrical transients;
(c) moisture; and
(d) other environmental conditions.

8.9.2
A component that bridges two circuits that are otherwise required to be isolated from one another shall be
one of the following types:
(a) A Y1 capacitor or two Y2 capacitors in series, complying with the antenna coupling requirements

specified in CAN/CSA-E60384-1 and CAN/CSA-E60384-14;
(b) Two capacitors connected in series. Each capacitor shall comply with the dielectric voltage withstand

test specified in Clause 9.4;
(c) Isolation provided by a transformer that complies with the dielectric voltage withstand test specified

in Clause 9.4 and the transformer construction requirements specified in this Standard; or
(d) Isolation provided by a transformer that complies with the dielectric voltage withstand test specified

in Clause 9.4 and the transformer construction requirements for Class 2 specified in CAN/CSA-C22.2
No. 223.

8.10 Protective devices

8.10.1
A protective device used for compliance with this Standard shall meet the requirements applicable to that
component. Protective devices include
(a) eutectic material;
(b) fuses;
(c) over temperature and over current protectors;
(d) thermal protectors; and
(e) similar devices intended to interrupt or limit the flow of current as a result of overload.

8.10.2
A protective device in a primary circuit shall not be connected in the neutral (grounded) conductor unless
the device simultaneously interrupts the grounded and ungrounded supply conductors.

8.10.3
An overcurrent protective device used for construction or performance requirements shall be inaccessible
to tampering, or it shall not be interchangeable with a device having a higher current rating.

8.10.4
The fuse type identification and ampere rating shall be marked in accordance with Clause 10.3.2 on or
adjacent to a user serviceable fuse or fuse holder.
