NEC Power-limited Wiring Requirements Installation 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. AC Power Nonpower-limited Output Circuits Power-limited Circuits Relay Contacts Nonpower-limited Circuit Input Circuits Power-limited Circuit Specific Application Power & SLC are Power-limited Circuits *If the SLC device does not match the one in this figure, refer to the SLC manual appendix, which contains wiring conversion charts for type V and type H modules.
