1.5.1
Some components and materials associated with
the risk of fire, electric shock, or personal injury
are required to
have component or material ratings in accordance
with the applicable national (U.S. and Canadian)
component or material requirements. These
components include: attachment plugs, battery
packs (rechargeable type, used with transportable
equipment), cathode ray tubes, circuit breakers,
communication circuit accessories, connectors
(used for current interruption of non-LPS circuits),
cord sets and power supply cords, direct plug-in
equipment, electrochemical capacitor modules
(energy storage modules with ultracapacitors),
enclosures (outdoor), flexible cords and cables,
fuses (branch circuit), fuseholders, ground-fault
current interrupters, industrial control equipment,
insulating tape, interconnecting cables,
lampholders, limit controls, printed wiring,
protectors for communications circuits,
receptacles, solid state controls, supplementary
protectors, switches (including interlock
switches), thermal cutoffs, thermostats, (multi-
layer) transformer winding wire, surge protective
devices, tubing, vehicle battery adapters, wire
connectors, and wire and cables.

1.6.1.2
A circuit for connection to the DC Mains Supply is
classified as a SELV Circuit, a TNV-2 Circuit or a
Hazardous Voltage Circuit depending on the
maximum operating voltage of the supply. This
maximum operating voltage shall include
consideration of the battery charging “float
voltage” associated with the intended supply
system, regardless of the marked power rating of
the equipment.
N/A
2.3.1
For TNV-2 and TNV-3 circuits with other than
ringing signals and with voltages exceeding 42.4
Vpeak or 60 Vd.c., 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 d.c.
under normal operating conditions.
N/A
2.3.2.1
In the event of a single fault between TNV and
SELV circuits, the limits of 2.2.3 apply to SELV
Circuits and accessible conductive parts.
N/A
2.6.2
Equipment with functional earthing is required to
be marked with the functional earthing symbol
(IEC 60417-6092).
N/A
2.6.3.4
Protective bonding conductors of non-standard
protective bonding constructions (e.g., printed
circuit traces) may be subjected to the additional
limited short circuit test conditions specified.
