DEFINITIONS FOR ARTICLE 725 |
| |
| Class
1 Circuit: |
The
portion of the wiring system between the load side of the overcurrent
device or power-limited supply and the connected equipment.
The voltage and power limitations of the source are in accordance
with NEC Section 725-21.
|
|
| Class
2 Circuit: |
The
portion of the wiring system between
the load side of a Class 2 power source and the connected equipment.
Due to its power limitation, a Class 2 circuit considers safety
from a fire initiation standpoint and provides acceptable protection
from electric shock.
|
|
| Class
3 Circuit: |
| The
portion of the wiring system between the load side of a Class
3 power source and the connected equipment. Due to its power
limitations, a Class 3 circuit considers safety from a fire
initiation standpoint. Since higher levels of voltage and current
than Class 2 are permitted, additional safeguards are specifed
to provide protection from an electric shock hazard that could
be encountered. |
