The following key national differences are based on requirements other than
national regulatory requirements.
national regulatory requirements.
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, 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, surge suppressors,
switches (including interlock switches), thermal
cutoffs, thermostats, multi-layer transformer
winding wire, tubing, wire connectors and wire
and cables

2.3.1
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.
