The United States of America and Canada have adopted a single, bi-
national standard, CAN/CSA C22.2 No. 60950-1/UL60950-1, First Edition,
which is based on IEC 60950-1, First Edition. This bi-national standard
should be consulted for further details on the national conditions and
differences summarized below.
national standard, CAN/CSA C22.2 No. 60950-1/UL60950-1, First Edition,
which is based on IEC 60950-1, First Edition. This bi-national standard
should be consulted for further details on the national conditions and
differences summarized below.
The following is a summary of the key national differences based on
national regulatory requirements, such as the National Electrical Code
(NEC) ANSI/ NFPA 70-2002, which are referenced in legislation and
which form the basis for the rules and practices followed in the
electrical and building installations.

1.1.1
All equipment is to be designed to allow
installations in accordance with the National
Electrical Code (NEC), ANSI/NFPA 70, the
Canadian Electrical Code (CEC), Part 1,
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.

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

1.7.1
Equipment for use on 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”.
