Add the following after the second paragraph: 

In Australia (this variation does not apply in New 
Zealand), the a.c. test voltage is: 

for 6.2.1 a): 3 kV; and 

for 6.2.1 b) and 6.2.1 c): 1.5 kV. 

NOTE 201 – Where there are capacitors across 
the insulation under test, it is recommended that 
d.c. test voltages are used. 

NOTE 202 – The 3 kV and 1.5 kV values have 
been determined considering the low frequency 
induced voltages from the power supply 
distribution system.

Canada and the United States of America have 
adopted a single, bi-national standard, CAN/CSA- 
C22.2 No. 60950-1/UL 60950-1, 

First Edition, which is based on IEC 60950-1, 
First Edition. Effective April 1, 2003, this standard 
may be used for product certification immediately, 
however, the previous version of the standard 
may also be used until April 1, 2005. 

Note: The previous version is CAN/CSA-C22.2 
No.60950-00/UL 60950 Third Edition, based on 
IEC 60950, 3rd Edition. Refer to the 

“IEC 60950, 3rd Edition, CA” section of this CB 
bulletin for the national differences in this version 
of the standard. 

This bi-national standard should be consulted for 
further details on the Special National Conditions 
and Other Differences summarized below. 

 P 

 

SPECIAL NATIONAL CONDITIONS 

 

 

Those requirements are identified as Special 
National Conditions since they are directly related 
to the Canadian Electrical Code (CEC), Part 1 
and the Canadian Building Code, which are 
referenced in legislation and which form the basis 
for the rules and practices followed in electrical 
and other building installations in Canada. 

Notes: 

- “CEC” denotes Canadian Electrical Code. 

- “NEC” denotes US National Electrical Code. 

- Due to common Canadian and US national 
differences, products that are in compliance with 
the Canadian national differences are also 
considered in compliance with the US national 
differences.

1.1.1 

All equipment is to be designed to allow 
installation in accordance with the National 
Electrical Code (NEC), ANSI/NFPA 70, the 
Canadian Electrical Code (CEC), Part I, 
CAN/CSA-C22.1, and when applicable, the 
National Electrical Safety Code, IEEE C2. Also, 
unless marked or otherwise identified, installation 
is allowed per the Standard for the Protection of 
Electronic Computer/Data-Processing Equipment, 
ANSI/NFPA 75. 

 P 

1.4.14 

For Pluggable Equipment Type A, the protection 
in the installation is assumed to be 20 A. 

 P 

1.5.5 

For lengths exceeding 3.05 m, external 
interconnecting flexible cord and cable 
assemblies are required to be a suitable cable 
type (e.g. DP, CL2) specified in the NEC. 

For lengths 3.05 m or less, external 
interconnecting flexible cord and cable 
assemblies that are not types specified in the 
NEC are required to have special construction 
features and identification markings. 

 P 

1.7.1 

Equipment for use on a.c. mains supply systems 
with a neutral and more than one phase 
conductor (e.g. 120/240 V, 3-wire) require a 
special marking format for electrical ratings. 

A voltage rating that exceeds an attachment plug 
cap rating is only permitted if it does not exceed 
the extreme operating conditions in Table 2 of 
CAN/CSA C22.2 No. 235, and if it is part of a 
range that extends into the Table 2 "Normal 
Operating Conditions." Likewise, a voltage rating 
shall not be lower than the specified "Normal 
Operating Conditions," unless it is part of a range 
that extends into the "Normal Operating 
Conditions." 

 N/A 

2.5 

Where a fuse is used to provide Class 2, Limited 
Power Source, or TNV current limiting, it shall not 
be operator-accessible unless it is not 
interchangeable.
