Verdict
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 
electrical and building installations. The bi-national standard (CAN/CSA C22.2 No. 60950-1/UL

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,

1.5.1 
Components of equipment must be suitable for 
the application, and must comply with the 
requirements of the equipment standard and the 
applicable national (Canadian and/or U.S.) 
component or material standards, as far as they 
may apply. 
The acceptance will be based on the following: 
I) A component Certified by a Canadian or U.S. 
National Certification Body (NCB) to a Canadian 
or U.S. component standard will be checked for 
correct application and use in accordance with its 
specified rating. Where necessary, it will also be 
subject to the applicable tests of the equipment 
standard. 
J) A component, which has a CB Test Certificate 
for compliance with a relevant IEC component 
standard, will be checked for correct application 
and use in accordance with its specified ratings. 
Where necessary, it will also be subject to the 
applicable tests of the equipment standard, and 
to the applicable tests of the Canadian and/or 
U.S. component or material standard, under the 
conditions occurring in the equipment. 
K) A component, which has no approval as in A) 
or B) above or which is used not in accordance 
with its specified ratings, will be subject to the 
applicable tests of the equipment standard, and 
to the applicable tests of the Canadian and/or 
U.S. component or material standard, under the 
conditions occurring in the equipment. 
L) Some components may require annual re-
testing, which may be carried out by the 
manufacturer, CSA International or another 
laboratory 
Critical components are IEC 
certified. See list of critical 
components in main CB report 
(§1.5.01). There may be 
additional requirements for 
components in Canada.

For TNV-2 and TNV-3 circuits with other than 
ringing signals and with voltages exceeding 42.4 
Vp or 60 Vdc, the maximum acceptable current 
through a 2000 ohm resistor (or greater) 
connected across the voltage source with other 
loads disconnected is 7.1 mA peak or 30 mA dc 
under normal operating conditions. 
No TNV circuitry. 
N/A 
2.3.2 
In the event of a single fault, the limits of 2.2.3 
apply to SELV Circuits and accessible conductive
