Installation NEC Power-limited (Class 2) Wiring Requirements
2.4 NEC Power-limited (Class 2) Wiring Requirements
Power-limited (Class 2) and nonpower-limited circuit wiring must remain separated in the cabinet.
All power-limited (Class 2) circuit wiring must remain at least 0.25” away from any nonpower-lim-
ited circuit wiring. Furthermore, all power-limited (Class 2) circuit wiring and nonpower-limited
circuit wiring must enter and exit the cabinet through different conduits. One such example of this
is shown below. Your specific application may require different conduit knockouts to be used. Any
conduit knockouts may be used. For power-limited (Class 2) applications, use of conduit is
optional.
