NEC Power-limited Wiring Requirements

2.4 NEC Power-limited Wiring Requirements
Power-limited and nonpower-limited circuit wiring must remain separated in the cabinet. All
power-limited circuit wiring must remain at least 0.25" away from any nonpower-limited circuit
wiring. Furthermore, all power-limited 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 applications, use of conduit is optional.
